Abstract

An object of the present invention is to provide an evaluation information collecting system in which evaluation information for an article on the consumer side can be utilized more effectively on the article providing side.
A retailer-side management system 2 acquires evaluation information for each individual product for a product from the consumer-side system 1 and aggregates the acquired evaluation information for each category related to the product. Evaluation aggregation information for each category is obtained, and the evaluation aggregation information for each category is transmitted to the processor side management system 3 specified from the category. The processor-side management system 3 distributes the evaluation aggregate information received from the retailer-side management system 2 to each material category based on the reflection rate for each material category of the article related to the evaluation aggregate information. The evaluated evaluation information is transmitted to the producer-side management system 4 related to each material category.

Description

  The present invention relates to an evaluation information collection system, an evaluation information collection method, and a program for collecting evaluation information for an article.

  Conventional traceability systems are known that attempt to provide information about products to consumers and the like. In this case, a unique product identifier is assigned to each product, and a database holding information about the product is prepared for each product identifier. The database is based on the product identifier attached to the product at a store or the like. And presenting information related to the product, or assigning a unique information identifier to each piece of information, and preparing a database holding information for each information identifier. In some cases, the database is searched based on the information identifier attached to, and information related to the product is presented. As a typical example of such a traceability system, for example, there is one for foodstuffs, and a public experiment or the like is actually performed.

  By the way, there is a concept of not only providing information to consumers and the like by a traceability system but also trying to use information obtained about the product on the product providing side.

For example, there is a conventional technique in which information obtained in the distribution process is used for quality control on the producer side (see, for example, Patent Document 1). The distribution product temperature management device disclosed in Patent Document 1 distributes a sensor-equipped data carrier together with products, collects environmental information on the route flowing from upstream to downstream of the distribution route, and accumulates the information in the data carrier. Quality control is performed based on the environmental information.
JP 2002-87523 A

  Consumers who consume various products have evaluation information for each product. Consumer evaluation information includes information about quality and other matters, and not only information related to the quality of the product, but also related to abnormalities such as poor quality and accidents (eg food poisoning, etc.) Information is also included.

  Such consumer evaluation information is considered to be very useful for consumers who provide products to consumers. For example, it is a product that processes and sells raw materials, and the quality changes depending on how each supplier handles the materials and products from the production of raw materials to the manufacture and sale of products. In such cases (for example, products such as foods), it is possible to improve quality control accuracy by collecting and propagating quality assessments for final products and using them on the upstream side of distribution. Expected.

  However, a method for effectively using evaluation information on the consumer side on the product provider side has not been known. For example, the distribution product temperature management device disclosed in Patent Document 1 collects environmental information on a route that flows from upstream to downstream of the distribution route, and does not collect evaluation information that the consumer has. There is a drawback that it is necessary to prepare a large number of data carriers according to the products actually distributed.

  An object of the present invention is to provide an evaluation information collection system, an evaluation information collection method, and a program capable of more effectively utilizing evaluation information for an article on the consumer side on the article providing side.

  According to the present invention, evaluation information for an article on the consumer side can be used more effectively on the article providing side.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  In the following description, an article (for example, sold or gifted) manufactured based on one or more materials (for example, a product or processed product) and transferred to a user (for example, a consumer, a purchaser, or a customer). An example in which consumer evaluations (e.g., evaluations related to quality) of products, products, premiums, etc.) are collected and propagated on the article providing side will be described. In the following, for the sake of convenience, the user is assumed to be a consumer, the transfer is assumed to be a sale, and the article is assumed to be a product. However, other words such as a purchaser, customer, gift, product, giveaway, etc.・ The operation is the same.

  FIG. 1 shows a configuration example of an evaluation information collection system according to an embodiment of the present invention.

  In the following explanation, companies that are located at each stage of the distribution channel from the production, manufacture and supply of materials to the processing / manufacturing of the product, retail, etc. are simply referred to as “traders”. "

  Here, a manufacturer (producer) that performs production or the like located at the starting point of the distribution channel, a manufacturer (processor) that performs processing or the like that is positioned in the middle of the distribution channel, and is positioned in the middle of the distribution channel (but immediately before the consumer) Consider retailers (retailers), etc., which are retailers.

  The producer is located at one end of the distribution channel and aims to sell the product. Here, a case where one or a plurality of types of products (for example, rice, meat, vegetables, etc.) is shipped to one or a plurality of processors is considered. In addition, although this product is a material when it sees from the goods (for example, lunch box etc.) which a processor ships, it is itself a goods in the transaction between a producer and a processor.

  The purpose of the processor is to purchase materials, process and manufacture products based on the materials, and sell them. Here, one or more ingredients (for example, rice, meat, vegetables, etc.) are purchased from one or more producers and processed to produce one or more types of new products (for example, lunch boxes). Consider the case where these are shipped to one or more retailers.

  The retailer is located immediately before the consumer at the other end of the distribution channel, and aims to sell a product (for example, a lunch box) to the consumer. Here, a case where one or a plurality of types of goods (for example, a lunch box) is purchased from one or a plurality of processors and sold to consumers is considered.

  As shown in FIG. 1, in this evaluation information collection system, each producer is provided with a producer-side management system 4, each processor is provided with a processor-side management system 3, and each retailer Each merchant is provided with a retailer-side management system 2. The producer side management system 4, the processor side management system 3, and the retailer side management system 2 are collectively referred to as a management system. It is assumed that management systems installed at the merchants can communicate with each other via a network at least between merchants with product exchanges (all management systems may be communicable or need to communicate). Only management systems may communicate with each other).

  In addition, although one contractor here assumes units, such as one factory, one store, and one establishment, for example, install one management system by making several stores etc. into one contractor. It is also possible to manage and process information, or to manage and process information by installing one management system, for example, by dividing each store into a plurality of businesses.

  Moreover, as FIG. 1 shows, the consumer side system 1 for inputting the information (evaluation information) regarding the evaluation with respect to each consumer's goods is provided. The consumer side system 1 may be, for example, one using a PC or the like of a consumer house (for example, a case where the consumer inputs evaluation information from a home PC) or a retailer who sells a product to the consumer. It may be provided in a store (for example, a case where a consumer (or a store clerk or the like instead) inputs evaluation information from a terminal in the store). The consumer side system 1 can communicate via a network with a retailer side management system 2 (that is, a retailer side management system 2 installed in a trader who sells the product) that should transmit evaluation information for a certain product. Suppose that

  In addition, the consumer side system 1, the retailer side management system 2, the processor side management system 3, and the producer side management system 4 in FIG. Various connection relationships may occur except that 1 is located on the most downstream side and the retailer side management system 2 is immediately before the consumer side system 1.

  For example, when a processor that manufactures a lunch box purchases rice and meat from the producer and other side dishes from other producers, other items are distributed between the producer and the processor in the distribution channel. A processor may enter. In this case, for example, as shown in FIG. 2 (a), another processor side management system 3 may enter before the processor side management system 3.

  In addition, when one supplier makes and sells lunch boxes, or when one supplier makes and sells lunch boxes, and also sells lunch boxes purchased from other vendors, one supplier is a processor and retailer. Sometimes it is a trader. In this case, for example, as shown in FIG. 2B, the retailer side management system 2 and the processor side management system 3 (or a management system integrating them) are installed in one trader.

  In addition, for example, when a retailer purchases and sells a product directly from a producer, or purchases and sells a product directly from a producer and also purchases and sells a bento from a processor, the distribution channel. In some cases, there may be no processor between the producer and the retailer. In this case, for example, as shown in FIG. 2C, the retailer side management system 2 may enter immediately after the producer side system 4.

  In addition to the above suppliers, for example, one or more products are purchased from one or more suppliers, and they are processed without processing (however, processing for maintaining quality (for example, temperature / humidity control, etc.) ) May be implemented), and it is also possible to handle distributors whose purpose is to ship to one or more suppliers. In this case, for example, as shown in FIG. 2 (d), the distributor is installed between the management system related to the distributor located in the preceding stage of the distributor and the management system of the dealer located in the subsequent stage. The distributor side management system 5 may enter.

  In addition to these, various variations are possible.

  Here, various information used in the following description will be described.

  It is assumed that identification information (trader ID) unique to each trader is given to each trader.

  Each product (for example, rice, meat, vegetables, hamburger, lunch box, etc.) is given identification information (individual product ID) unique to the product (individual product). It is assumed that an individual product ID unique to a product can be recognized by some means. For example, a holding unit that holds an individual product ID of the product (for example, an item printed with an individual ID, or a device that requires a reading device such as an electronic tag or a barcode) ) May be given. Further, for example, it may be written on a receipt, a receipt or a purchase statement issued by a retailer. In addition, for example, the transaction number (such as written on a receipt issued by a retailer) is used as a key, or the transaction date and time (such as recorded on a receipt issued by a retailer) It may be possible to search from a retailer's server or the like by using a combination with a customer ID (issued to the consumer) as a key.

  Here, the individual product ID has a three-level structure and is given by (producer ID, type ID, individual product identification data).

  The producer ID is a trader ID of a trader (for example, a producer or a processor) that produces or manufactures the product (individual product). Note that the producer ID may be special identification information provided separately from the supplier ID, and the other may be specified from one to the other between the producer ID and the supplier ID.

  The type ID is identification information indicating the type of the product. The type ID of a certain type of product is assigned so as to be unique within the range of the producer ID to which the product belongs.

  The classification of types may be appropriately defined for each producer ID according to the purpose. Specifically, for example, at a level such as lunch box, rice ball, sandwich, etc., or more subdivided, lunch box A, lunch box B, lunch box C, ..., rice ball E, rice ball F, ..., sandwich H, Various methods such as classification at the level of sandwich I,.

  The individual product identification data is data for identifying individual products (individual products). The individual product identification data of each product is assigned so as to be unique within the range of the set of the producer ID and the type ID to which the product belongs. The individual product identification data only needs to be able to identify individual products within the range of the same producer ID and type ID. For example, a serial number or other information may be used. May be.

  This individual item ID is the same as the individual item ID used in the traceability system when there is a traceability system (a system that provides a function for retrieving information related to the item from the individual item ID of the item). Although it is preferable to use a single product ID, it may be provided separately from the individual product ID used in the traceability system.

  Assume that consumer evaluation information for a product is given by (evaluator ID, individual product ID, evaluation data).

  The evaluator ID is identification information for identifying the evaluator related to the evaluation information, that is, the consumer, and at least the retailer-side management system 2 that should transmit the evaluation information can identify the consumer. That's fine. For example, a retailer related to the retailer-side management system 2 may use a customer ID issued to the consumer.

  The evaluation data is data indicating the evaluation made by the evaluator, that is, the consumer, on the individual product. As will be described in detail later, it is preferable that the evaluation data be handled in a normalized manner in order to correct the deflection and weight of each consumer (evaluator).

  The merchandise category is a unit for collecting evaluation information, and is given here by (upstream vendor ID, producer ID, type ID).

  The part of the product category (producer ID, type ID) corresponds to the product ID obtained by removing the product identification data from the product ID.

  In the product category, the upstream trader ID is a trader ID of a trader located in the preceding stage in the distribution channel as viewed from the trader related to the management system for processing the evaluation information, and is usually a trader ID of the trader who delivered the product. .

  For example, in the retailer-side management system 2 related to the retailer S1 that retails the lunch A, when processing the evaluation information for the lunch A, the upstream trader ID is the trader of the processor C1 who delivered the lunch A to the retailer S1. It is an ID, and the producer ID is also the vendor ID of the processor C1 who manufactured the lunch.

  Also, for example, in the above case, if the distributor F1 is considered between the processor C1 and the retailer S1, the upstream distributor ID is the distributor ID of the distributor F1 who has delivered the lunch A to the retailer S1. The producer ID is the trader ID of the producer P1 who produced the lunch box A.

  Also, for example, when the processing side management system 3 relating to the processor C1 that manufactures the lunch A, when the rice R that is the material of the lunch A is viewed as a product, the upstream supplier ID delivers the rice R to the processor C1. The producer ID of the producer P1 is also the producer ID of the producer P1 that produced the rice R.

  Each management system can know the upstream contractor ID by some means. For example, for each unit of a company including a unit of a supplier or a plurality of suppliers, or for all target individual items, an individual product ID and a supplier ID of a supplier that delivered the product (or One or more servers are provided on the network for managing the individual product ID, the trader ID of the trader who delivered the product, and the trader ID of the trader who received the product on the network. However, by making an inquiry to a predetermined server on the network based on the individual item ID of the item (or the individual item ID of the item and the vendor ID of the vendor who received the item), The supplier ID of the supplier that has been delivered may be acquired as the upstream supplier ID. Also, for example, each management system has a database having a function of managing the individual product ID and the supplier ID of the supplier that delivered the product (this is the upstream supplier ID) in association with each other, The management system may be able to acquire the upstream supplier ID by searching the database using the individual product ID as a key.

  Each management system, when processing the evaluation information (evaluator ID, individual product ID, evaluation data), obtains the upstream supplier ID from the individual product ID as described above, so that the product is obtained from the individual product ID and the upstream supplier ID. A category can be obtained.

  Next, a configuration example of each management system will be described.

  In FIG. 3, the example of a structure of the retailer side management system 2 is shown. FIG. 4 shows an example of the processing procedure of the retailer side management system 2.

  As shown in FIG. 3, the retailer-side management system 2 of this configuration example includes an evaluation information collection unit 21, an evaluation processing unit 22, a totalization processing unit 23, and a transmission unit 24. The retailer-side management system 2 may include a customer management database (or a database having an equivalent function such as a sales record database) 28 connected to the POS terminal 29 in the store.

  The evaluation information collection unit 21 collects evaluation information (evaluator ID, individual product ID, evaluation data) including evaluation data by consumers for individual products via the consumer side system 1 (step S21).

  The evaluation processing unit 22 confirms the validity of the collected evaluation information (step S22). The evaluation information is preferably handled after normalization.

  The tabulation processing unit 23 tabulates the evaluation information whose validity has been confirmed for each product category (step S23).

  As already described, the product category is a group of products that can be identified by (upstream vendor ID, producer ID, type ID). That is, the totalization processing unit 23 treats the same type of products (products belonging to the same producer ID and type ID) delivered from the same supplier as a group.

  The transmission unit 24 transmits the evaluation aggregation information aggregated for each product category to the management system related to the upstream vendor (the management system related to the upstream vendor ID included in the product category) (step S24).

  FIG. 5 shows a configuration example of the processor side management system 3. FIG. 6 shows an example of the processing procedure of the processor side management system 3.

  As shown in FIG. 5, the processor side management system 3 of this configuration example includes a reception unit 31, a redistribution processing unit 33, and a transmission unit 34.

  The receiving unit 31 receives the evaluation aggregation information totaled for each product category from the management system related to the downstream merchant (step S31).

  The redistribution processing unit 33 redistributes the evaluation aggregation information totaled for each product category with respect to each material (or each material and processing by itself) that is the basis of the product (step S32). The redistribution processing unit 33 is a derivative type of the aggregation processing unit 23 of the retailer side management system 2.

  The transmitter 34 transmits the redistributed evaluation aggregate information to the management system related to the upstream contractor (step S33).

  In FIG. 7, the example of a structure of the producer side system 4 is shown. FIG. 8 shows an example of a processing procedure of the producer side system 4.

  As shown in FIG. 7, the producer side system 4 of this configuration example includes a receiving unit 41.

  The receiving unit 41 receives the redistributed evaluation aggregation information from the management system related to the downstream vendor (step S41).

  The distributor side management system may be provided with a receiving unit, a redistribution processing unit, and a transmission unit as in the case of the processor side management system 3 (the same product may be exchanged with different vendors). In order to reflect the procedure, a redistribution processing unit is provided).

  Hereinafter, each management system will be described in more detail.

  First, the retailer-side management system 2 (and exchanges with other systems) will be described.

  An evaluator (consumer, etc.) inputs evaluation information (evaluator ID, individual item ID, evaluation data) for a product (individual item) from the consumer side system 1 and collects evaluation information of the retailer side management system 2 The unit 21 acquires and accumulates this evaluation information.

  For example, the evaluation information collection unit 3 provides a homepage on the WWW (World Wide Web), and the evaluator accesses the homepage from the consumer side system 1 and writes the evaluation information so as to acquire the evaluation information. Alternatively, the evaluator may acquire the evaluation information by transmitting an e-mail including the evaluation information from the consumer system 1 to the e-mail address of the evaluation information collection unit 3. The evaluation information may be acquired by the evaluation person writing the evaluation information from a terminal installed in the store (for example, the consumer side system 1 connected to the evaluation information collecting unit 3 via the LAN), You may use them together.

  The evaluation processing unit 22 determines whether or not the collected evaluation information for each individual item / evaluator is legitimate information for the actually sold individual item (or is actually sold to the evaluator). Whether it is legitimate information for the individual product.

  This confirmation is performed by specifying a transaction such as a customer ID and a transaction number, a customer ID and a date, a customer ID and a transaction number and a date, or a transaction number and a date from a POS terminal in the store (see 29 in FIG. 3). The first authentication data to be enabled and the POS data such as the individual item ID of the product (see 20 in FIG. 3) related to the transaction are sent to the customer management database (see 28 in FIG. 3) and accumulated. In addition, the evaluator inputs the second authentication data such as the transaction number or the customer ID described in the receipt or the like when inputting the evaluation information, and the evaluation processing unit 22 The contents and the second authentication data acquired together are compared with the POS data stored in the customer management database 28 and the first authentication data, and if there is a match, it is actually sold. Correct for individual item ID Information (or whether or not it is legitimate information for the individual item ID of the individual item sold to the consumer of the evaluator ID = customer ID). .

  The evaluation processing unit 22 removes the evaluator ID from the evaluation information only for the evaluation information confirmed to be legitimate, and forms the evaluation information (individual item ID, evaluation data) for each individual item. The evaluation processing unit 22 preferably normalizes the evaluation information for each evaluator ID, for example.

  In this embodiment, the case where the customer ID is used as the evaluator ID of the evaluation information is mainly described. However, in this case, the evaluation information can be collected from consumers who do not have the customer ID. Also good. For example, for a consumer who does not have a customer ID, an ID prepared for a consumer who does not have a customer ID may be used as the evaluator ID. In addition, for example, as an ID prepared for a consumer who does not have a customer ID, a plurality of types may be prepared for each consumer's age, sex, and the like.

  In this embodiment, the case where the evaluator ID is essential for the evaluation information is mainly described, but it is also possible to handle the evaluation information without specifying the evaluator. In this case, the evaluator ID may be omitted.

  In cases where there is another mechanism for ensuring the validity of evaluation information, or cases where all evaluation information is treated as being valid, confirmation of the validity of the evaluation information described above can be omitted. .

  Now, evaluation information (individual product ID, evaluation data) for each individual product is given from the evaluation processing unit 22 to the aggregation processing unit 23.

  The aggregation processing unit 23 obtains the upstream supplier ID from the individual product ID for the given evaluation information (individual product ID, evaluation data), and then aggregates by product category (upstream supplier ID, producer ID, type ID). To do.

  Note that the evaluation information aggregated for each product category is referred to as “evaluation aggregation information”. Further, the evaluation data aggregated for each product category is referred to as “evaluation aggregate value”.

  For example, an integer of several stages can be used as the value used for the evaluation data. For example, various methods such as a binary value of 0 or 1, a five-stage integer of 1 to 5, and a five-stage integer of −2 to +2 are possible. In the following description, a case where a method using an integer value of −2 to +2 is used is described as an example, but any method may be used as long as it is unified in the entire system.

Here, various methods for collecting evaluation information are conceivable. For example, you may select suitably regarding the value used for evaluation data. As a simple example, for example, an arithmetic average (evaluation aggregate value = sum of evaluation data / total number of evaluation data) or a weighted average (E _{t + 1} = α · E _t + β · e) is used. Can do. In the weighted average, E _t is an evaluation aggregate value at the time of the t-th evaluation, e is a value of newly obtained evaluation data, α and β are parameters that are arbitrarily determined, and are larger than 0 where α + β = 1. A number less than one. Further, as the evaluation aggregate value, data of a table indicating the number of detected pieces of each evaluation data (for example, when the evaluation data is an integer value in five stages of −1 to +2, −1 is 3 and −2 is 4) For example, data indicating that 10 is 0, 20 is +1, and 4 is +2).

  Evaluation aggregate information for each product category is given by (evaluation aggregate value, auxiliary information).

  The evaluation aggregate value is data such as a value or a table obtained as described above.

  The auxiliary information includes at least an evaluation weight. As the evaluation weight, for example, the number of evaluation data (that is, the number of evaluation information) that is the basis of the evaluation aggregate value can be considered.

  In addition, it is preferable that the auxiliary information includes a list of individual product IDs of individual products related to (all or a part of) the evaluation information that is the basis of the evaluation aggregate value. In the list of individual IDs, instead of using all the bits of the individual ID, a method that uses only a part of the bits of the individual ID according to the purpose (for example, from a part of the bits of the individual ID When a lot of individual items can be specified, a method using only a part of bits of the individual item ID) is also possible. In the following, a case where the auxiliary information includes a list of individual product IDs will be described as an example.

  In addition, the auxiliary information includes, for example, the variance or standard deviation when the evaluation aggregate value is an average value, and the period during which the evaluation information for each individual product / evaluator that is the basis of this evaluation aggregation information is collected. Various information such as information indicating the date and time when the evaluation aggregation information immediately before the evaluation aggregation information is passed to the transmission unit 24 may be included.

  The evaluation aggregation information is passed to the transmission unit 24 together with the product category, that is, in the form of (product category, evaluation aggregation information). Here, the timing to be passed to the transmission unit 24 is determined by the following mechanism. Shall be.

  FIG. 9 shows an internal configuration example of the aggregation processing unit 23. In this case, the aggregation processing unit 23, for each product category, in addition to the aggregation unit 231 that performs the process of calculating the evaluation information for each product category described so far, (Evaluation aggregated information aggregated from transmission to present), transmission date and time of the previous evaluation aggregated information (or a fixed time at which the evaluation aggregated information should be transmitted), previous evaluation aggregated information, and threshold of fluctuation of evaluation aggregated value It includes an information holding unit 232 to hold, and a timing control unit 233 that controls the timing of passing the current evaluation aggregate information to the transmission unit 24 (or the timing of sending the current evaluation aggregation information from the transmission unit 24). The timing determination unit has two types of mechanisms for determining timing: a timer mechanism and an abnormality detection mechanism.

  First, the aggregation processing unit 23 of the aggregation processing unit 23 uses the timer mechanism of the timing control 233 to determine that a predetermined time has passed since the previous evaluation aggregation information was sent (or that a predetermined time has been reached). Is recognized, the currently collected total (product category, evaluation aggregation information) is passed to the transmission unit 24.

  In addition to the above, the aggregation processing unit 23 of the aggregation processing unit 23 uses the abnormality detection mechanism of the timing control unit 233 to change the evaluation aggregate value (the evaluation aggregate value included in the current evaluation aggregation information and the previous evaluation). Even when the difference from the evaluation aggregate value included in the aggregate information exceeds a predetermined threshold value, (product category, evaluation aggregate information) is passed to the transmission unit 24. In addition, when an abnormality is detected by this abnormality detection mechanism (a change in the evaluation aggregate value exceeds a predetermined threshold), an e-mail or the like is sent to the manager of the merchant related to the retailer-side management system 2 The information regarding the content of the detected abnormality may be notified using the means.

  When the transmission unit 24 receives (product category, evaluation aggregation information) from the aggregation processing unit 23, the distribution channel to which this (product category, evaluation aggregation information) should be transmitted from the upstream supplier ID included in the product category. The communication method to the management system (the processing company side management system 3 in FIG. 1) related to the former stage in FIG. For example, the receiving unit of the management system as the transmission destination can be specified by a URL uniquely determined from the vendor ID (upstream vendor ID). For this specification, ONS defined by EPCglobal or a similar directory service may be used.

  The transmission unit 24 adds the merchant ID related to the management system to which the transmission unit 24 belongs to the received (product category, evaluation aggregation information) as a transmission side vendor ID, and (transmission side vendor ID, product category, evaluation aggregation information). ) = (Transmission side vendor ID, (upstream vendor ID, producer ID, type ID), (evaluation aggregated value, auxiliary information such as a list of evaluation weights and individual product IDs))) Send to system receiver.

  The transmission unit 24 of the retailer-side management system 2 and the reception unit of the management system on the reception side communicate with each other in accordance with a communication method defined by a convention such as XML RPC or HTTP. It should be noted that communication between the transmission unit and the reception unit is performed securely using public key cryptography corresponding to the trader ID related to the management system to which they belong, PKI, or a similar mechanism. desirable.

  Next, the processor side management system 3 (and exchanges with other systems) will be described.

  The reception unit 31 of the processor side management system 3 is as described above as the reception unit of the management system on the reception side.

  Upon receiving (transmission side vendor ID, product category, evaluation aggregation information), the receiving unit 31 deletes this (transmission side vendor ID, product category, evaluation aggregation information) or transmission side vendor ID (product category, evaluation aggregation) Information) to the redistribution processing unit 33. Prior to this, the receiving unit 31 receives the received information and a sales record database (or a database having an equivalent function), for example, as in the evaluation information collecting unit 21 of the retailer-side management system 2. It is preferable to verify the legitimacy of the received information (which is certainly a product shipped to the merchant associated with the transmitting merchant ID) by collating the data.

  Here, the redistribution processing unit 33 performs the redistribution processing immediately after receiving (transmission side vendor ID, product category, evaluation aggregation information) or (product category, evaluation aggregation information) from the reception unit 31. To do.

  Various variations can be considered for this redistribution processing.

  A specific example of the redistribution process will be described later. The redistribution process basically uses the given (product category, evaluation aggregated information) as (first product category, evaluation aggregated information). In addition, one or a plurality of (second product category, evaluation aggregation information) is generated.

  Here, the second product category includes a processor (for example, a lunch box) based on the processor related to the processor-side management system 3 and a product (for example, a lunch box) related to the first product category. , Rice, hamburg) in a transaction with a supplier (for example, a producer of a product such as rice as a material or a processor that manufactured a processed product such as a hamburger as a material) This is the product category of the product (for example, rice, hamburger) when the material itself that is the product of the product is considered as a product, and (upstream supplier ID, production) as in the first product category (Person ID, type ID).

  That is, the upstream supplier ID in the second product category (upstream supplier ID, producer ID, type ID) is the supplier ID of the supplier who delivered the product related to the second product category, and the producer ID is the second It is a trader ID of a trader who produced a product related to the product category. Further, (producer ID, type ID) is obtained by deleting individual product identification data from the individual product ID of the product related to the second product category.

  However, when considering the distribution of the processor to the processing technology of the processor, the second product category (upstream supplier ID, producer ID, type related to the distribution of the processor to the processing technology of the processor As for (ID), for example, the upstream supplier ID and the producer ID are used as the supplier ID of the processor, and the type ID is used as the type ID indicating the processing related to the product of the first product category, or the upstream supplier ID is null. Various forms such as a producer ID as a supplier ID of the processor and a type ID as a type ID related to the first product category or a type ID indicating processing related to a product in the first product category. Is possible.

  The evaluation aggregate information related to the second product category relates to the result of distributing the evaluation aggregate information related to the first product category. For example, the result of allocating the evaluation weight included in the auxiliary information included in the evaluation aggregate information related to the first product category to the evaluation weight included in the auxiliary information included in the evaluation aggregate information related to the second product category , A form in which information indicating a distribution method is added to auxiliary information included in the evaluation aggregate information related to the second product category, or an evaluation aggregate value included in the evaluation aggregate information related to the second product category Various forms such as a form in which the evaluation aggregate value included in the evaluation aggregate information related to the first product category is allocated are possible.

  Hereinafter, an example of the reallocation process will be described.

  For example, in the case of a processor, one or more materials are purchased from one or more suppliers, and are produced and shipped as one or more types of products. At this time, looking at each produced product, it can be seen that it is manufactured from a plurality of materials.

  Here, for example, if a product is manufactured from three types of materials, the weight of evaluation for the product is the quality of each material (or the processing technology of the processor added to this) ).

  Therefore, when the processing technology of the processor is not considered, the evaluation weight (for example, the number of evaluation data based on the evaluation aggregate value) m included in the given evaluation aggregate information is set to the first Is multiplied by r1, the second material is multiplied by r2, and the third material is multiplied by r3 (where 0 <r1, r2, r3 <1, and r1 + r2 + r3 = 1), m · A method is conceivable in which r1, m · r2, and m · r3 are transmitted to and reflected in upstream contractors (first to third material suppliers), respectively.

  Instead of the above transmission method, E · r1, E · r2, and E · r3 obtained by multiplying the evaluation aggregate value E by m, r1, r2, and r3, respectively, are transmitted to upstream contractors. It is also possible to reflect and reflect the values of r1, r2, and r3 to upstream contractors without reflecting or calculating the distribution itself.

  Here, a value indicating a ratio reflected upstream such as r1, r2, and r3 is referred to as a reflection rate. The reflection rate may be changed according to the ratio of the amount of material used from the supplier in each processor, the ratio of the price of the material, or the like.

  When there is only one material, the evaluation aggregate value included in the given evaluation aggregation information is transmitted and reflected as it is to the upstream contractor.

  Also, redistribute by a plurality of methods and process the results (for example, when redistributing evaluation weights, average the evaluation weights distributed by each distribution method for each writing material, etc.) Such a method is also possible.

  By the way, it is considered that the contribution of the processing technology of the processor to the weight of evaluation varies depending on the degree of processing. For example, in the case of producing daikon salad as a product from daikon as a material and the case of producing pickles as a product from radish as a material, the latter is considered to have a higher rate of evaluation for processing. . Therefore, in the latter case, the processor itself can be included in the distribution of the evaluation aggregate information. In this case, for example, a predetermined ratio (for example, 50%) r0 is set as a reflection rate to the processing, and 1-r0 (for example, 50%) is multiplied by distribution ratios r1, r2, r3,. R1 ′, r2 ′, r3 ′... Obtained in this manner may be used as the reflection rate for each material.

  In addition, even if it is the same kind of material at the time of a process, what was delivered from several suppliers can be used. In such a case, for example, assuming that the auxiliary information included in the evaluation aggregation information includes a list of individual product IDs, the individual product IDs indicated by the individual product ID list and the processing for the individual product IDs are performed. By collating records of detailed information about the materials used at times, it is possible to estimate the supplier corresponding to the obtained evaluation.

  As described above, one or a plurality of (commodity category, evaluation aggregate information) redistributed is transferred from the redistribution processing unit 33 to the transmission unit 34.

  In the above description, the redistribution processing unit 33 performs the redistribution processing immediately after receiving (transmission side vendor ID, product category, evaluation aggregation information) or (product category, evaluation aggregation information) from the reception unit 31. Although described as a thing, like the totalization processing unit 23 of the retailer-side management system 2, the materials may be totalized and then redistributed.

  In this case, as with the aggregation processing unit 23 of the retailer-side management system 2, one or a plurality of (first product category, evaluation aggregation information) are aggregated by two types of mechanisms, a timer mechanism and an abnormality detection mechanism. What is necessary is just to redistribute to (2nd merchandise category, evaluation aggregation information), and to determine the timing which passes this to the transmission part 34. FIG.

  When the redistribution processing unit 33 receives one or a plurality of (distributed product categories and evaluation aggregate information) from the redistribution processing unit 33, the transmission unit 34 uses the (commodity category and evaluation) from the upstream vendor ID included in the product category. The communication method to the management system (the producer-side management system 4 in FIG. 1) related to the upstream supplier in the distribution channel to which the aggregate information) should be transmitted is acquired. For example, the receiving unit of the management system as the transmission destination can be specified by a URL uniquely determined from the vendor ID (upstream vendor ID). For this specification, ONS defined by EPCglobal or a similar directory service may be used.

  The transmission unit 34 adds a merchant ID related to the management system to which the transmission unit 34 belongs to the received one or more (distributed product category, evaluation aggregation information) as a transmission side vendor ID, (ID, product category, evaluation aggregate information) in the form of a transmission destination to the receiving unit of the management system.

  The transmission unit 34 of the processor side management system 3 and the reception unit of the management system on the reception side communicate with each other in accordance with a communication method defined by a protocol such as XML RPC or HTTP. It should be noted that communication between the transmission unit and the reception unit is performed securely using public key cryptography corresponding to the trader ID related to the management system to which they belong, PKI, or a similar mechanism. desirable.

  Next, the producer side management system 4 (and exchanges with other systems) will be described.

  As described above, the receiving unit 41 of the producer-side management system 4 receives (transmission side supplier ID, product category, evaluation aggregation information) as the receiving unit of the management system on the receiving side. In addition, it is preferable that the receiving unit 41 verifies the validity of the received information (which is certainly a product shipped to the supplier related to the transmission side supplier ID), as in the case of the receiving unit so far.

  In the end, the processor or producer evaluates the evaluation value, particularly the part directed to the supplier itself (when evaluating toward the supplier itself) or the evaluation aggregate information in the receiving unit. It is also possible to perform abnormality detection and quality control.

  In the following, a specific example of a food distribution network will be described.

  The food distribution network includes, for example, beef, pork, tomatoes, lettuce, peppers, bread, rice, etc. as ingredients, and there are multiple producers, material processors, wholesalers (distribution), and final processing for each. It consists of traders (final products), retail distributors, dealers, etc. The primary processor purchases a collective amount of ingredients from one or more producers and sells them as a food product with stable quality. In particular, in meat, not only carcass is cut into meat of a size that can be used as a product, but processing such as mince can be considered. Here, as the secondary processing company, for example, a company that purchases food and makes a lunch box is assumed. In some cases, the store also serves as a secondary processor (eg, a hamburger store). In addition, not all products are handled by all traders. Some products may be lined up in stores without processing.

  Here, with reference to FIGS. 10 and 11, the present embodiment will be described with a specific example of a distribution network related to a simplified lunch box.

  First, C1 and C2, which are lunch box manufacturers, are considered as processors. The processor C1 manufactures a specification lunch box A and sells it to a plurality of retailers, and the processor C2 manufactures a specification lunch box B and sells it to a plurality of retailers (see FIG. 10 shows only retailers S1 and S2 and omits other retailers).

  Further, the processors C1 and C2 purchase ingredients. Producers that supply food do not necessarily overlap all about the processors C1 and C2, but some overlap, some use their own vendors, or all are different Is also possible. That is, as the producer, there are a producer who delivers only to the processor C1, a producer who delivers only to the processor C2, and a producer who delivers both. There may be producers who have not delivered, but such producers are irrelevant to the system).

  FIG. 10 illustrates a producer P1 delivering rice to the processor C1, a producer P2 delivering water, a producer P3 delivering pork, and a producer P4 delivering onions. The other producers who deliver other materials to the processor C1 and the producers who deliver to other processors are omitted.

  In this specific example, the distributor is not considered, but it is desirable that each distributor also participates in the distribution network in order to take into account quality control during goods transportation.

  Now, it is assumed that the retailers S1, S2, etc. each manage a customer, issue a customer ID to each customer, and issue a corresponding customer management card. Further, the customer ID is assumed to be managed by each retailer, and is not used for exchange between the merchants.

  Hereinafter, the description will be given focusing on the retailer S1, but the same applies to other retailers.

  The consumer (customer) a makes a purchase such as lunch A at the retailer S1. At the time of shopping, the product (individual item) and the customer management card are detected at the POS terminal (register) at the same time. At this time, the POS terminal generates a set of (evaluator ID, individual product ID) as evaluator ID = customer ID for each product purchased by the consumer, and the customer management database (or sales) Registered in a database having equivalent functions such as a recording database). Each registration data in this database may be discarded with reference to the expiration date of the product.

  Similarly, the consumer (customer) b purchases the lunch A etc. at the retailer S1, the consumer (customer) c buys the lunch A etc. at the retailer S2, and the consumer (customer) d , Shopping for lunch A etc. at retailer S2. In addition, in FIG. 10, other shopping of consumers ad and shopping of consumers other than consumers ad are omitted.

  Assume that the retailer S1 wants to know the degree of satisfaction regarding a product bought by a consumer together with some incentive. This is called evaluation information for a product. In this example, the evaluation information is assigned an evaluation related to quality (for example, -2 to +2 is a five-level evaluation, +2 is the best). For example, other types of information may be used.

  The evaluation information collection unit 21 of the retailer-side management system 2 of the retailer S1 uses means such as WWW, for example, to collect evaluation information. The consumers a and b input the customer ID written on the customer management card received from the retailer S1 and the individual item ID such as lunch A written on the receipt or the like to the WWW server of the retailer S1. Similarly, the consumers c and d also input the customer ID written on the customer management card received from the retailer S2 and the individual item ID such as the lunch A written on the receipt or the like to the WWW server of the retailer S2. . The same applies to other purchases of consumers a to d and purchases of other consumers.

  In addition, by describing the URL including customer ID information on the customer management card using means such as a two-dimensional code, the labor of the consumer can be reduced or the customer can be confirmed by using a secret such as a password. Alternatively, an ID may be issued for each receipt, a receipt ID may be input instead of an individual product ID, and a product to be evaluated may be selected from the corresponding transaction.

  Evaluation information for the lunch box A given by the consumers a, b, etc. is obtained in the form of (evaluator ID, individual product ID, evaluation data). However, here, the evaluator ID is equal to the customer management ID in the retailer S1.

  For example, as illustrated in FIG. 10, the evaluation information for the lunch box A given from the consumer a to the retailer S1 is (evaluator ID, individual item ID, evaluation data) = (a, (C1, A, n1). ), E11), and the evaluation information for the lunch box A given from the customer b to the retailer S1 is (evaluator ID, individual item ID, evaluation data) = (b, (C1, A, n2), E12), etc. Become.

  In order to confirm that this evaluation information is certainly the evaluation information associated with the purchase of the product, the evaluation processing unit 22 responds by checking with a sales record database or the like (evaluator ID, individual product ID). Only when it is confirmed that the information set of () exists, the evaluation information is handled in a reliable manner. If there is no corresponding set of information, the evaluation information is discarded because there is no purchase record.

  Here, the evaluation information given from the customers a, b, etc. includes a deviation for each customer. There are differences in mean values (positive customers and negative customers) and standard deviations (customers who speak less and customers who speak less). In addition, there are cases where simple customer preferences (such as reciting a specific producer) are included.

  In order to exchange evaluation information (actually aggregated information) between stores (between management systems), it is desirable to use information having as little bias as possible between stores (between management systems). For example, by taking a history of evaluation information for each customer and performing normalization such that the average value of the evaluation information is 0 and the variance is 1, it is possible to exchange evaluation information between vendors.

  Next, the evaluation processing unit 22 deletes the evaluator ID (= customer ID) from the normalized (evaluator ID, individual product ID, evaluation information), and the combination of (individual product ID, evaluation information) Is passed to the aggregation processing unit 23.

  The aggregation processing unit 23 aggregates the given (individual product ID, evaluation information) for each product category as described above.

  The merchandise category is given by a trader ID and type ID included in the individual product ID, and a trader ID of a trader who delivered the individual product to the retailer (upstream trader ID, producer ID, type ID).

  For example, the product category of the lunch box A manufactured by the processor C1 and delivered to the retailer S1 is (upstream supplier ID, producer ID, type ID) = (C1, C1, A) and the like.

  The aggregation processing unit 23 evaluates for each product category including, for example, the aggregation start date and time, the final aggregation date and time, the previous evaluation information transmission date and time, the number of evaluation information given from the previous evaluation value transmission time to the present, and the like. Aggregate information.

  The aggregation processing unit 23 is driven by the two mechanisms of the timer mechanism and the abnormality detection mechanism as described above, and sends the evaluation aggregation information to the transmission unit 24. This sending mechanism operates for each product category. For example, the timer mechanism in the retailer S1 is set to operate at 1 am, and the abnormality detection mechanism has a fluctuation of the evaluation aggregate value from the previous transmission exceeding 50%, and the aggregation processing unit 23 When the number of given evaluation information exceeds a steady value (average value of the history so far), it shall be transmitted. For example, when there is an accident in the product and the number of claims increases rapidly, it is considered that a large number of negative evaluation information arrives than normal and the abnormality detection mechanism operates. Note that the abnormality detection mechanism may issue a warning to a store manager or the like by means of e-mail or the like.

  The transmission unit 24 receives a set of (product category, evaluation aggregation information) from the aggregation processing unit 23.

  The merchandise category includes the ID of the merchant who delivered the merchandise to the retailer S1. From this supplier ID, using the ONS defined by EPCglobal, other directory services, or a pre-defined table, etc., the receiving unit of the management system related to the supplier (for example, the processor of the processor C1) The receiving unit 31 of the side management system 3).

  Here, it is assumed that the transmission unit 24 of the retailer-side management system 2 of the retailer S1 and the reception unit of the management system related to the supplier communicate with each other by HTTP on the Internet (TCP / IP). The transmitting unit 24 can transmit the HTTP request to the receiving unit of the management system related to the supplier by finding the URL corresponding to the receiving unit of the management system related to the supplier from the supplier ID of the supplier. At this time, communication safety may be ensured between the transmitting unit and the receiving unit using TLS, SSL, IPSec, PKI, or the like.

  Here, since the retailer S1 purchases lunch from the processors (lunch manufacturers) C1, C2, etc., the transmitter 24 manages the processor side management system related to the processors C1, C2, etc. for each product category. 3 receivers 31 are found, and a set of information of (transmission side supplier ID, product category, evaluation aggregation information) is transmitted.

  For example, as illustrated in FIG. 10, evaluation aggregation information obtained by aggregating evaluation information for the lunch box A given to the retailer S1 from the consumers a, b, etc. is transmitted to the processor side management system 3 related to the processor C1. In this case, data to be transmitted (transmission side supplier ID, product category, evaluation aggregation information) = (S1, (C1, C1, A), (E, m, list)). Here, E represents an evaluation aggregate value, m represents an evaluation weight, and list represents a list of individual product IDs.

  Hereinafter, the description will be given focusing on the processor C1, but the same applies to other processors.

  The receiving unit 31 of the processor side management system 3 related to the processor C1 surely receives the individual item ID list included in the evaluation aggregation information received as necessary to the processor side management system 3 to which the receiving unit 31 belongs. After confirming whether the processing company C1 has been shipped from the processing company C1 to the management system to which the transmission unit belongs (in the case of this specific example, the retailer S1 according to the retailer side management system 2 to which the transmission unit 24 belongs), The received evaluation aggregation information is passed to the redistribution processing unit 33.

  The following description focuses on the redistribution of evaluation aggregation information for the lunch box A manufactured by the processor (lunch manufacturer) C1 and delivered to the retailer S1, but the same applies to other products.

  The redistribution processing unit 33 of the processor C1 has a mechanism for determining the distribution of the evaluation aggregate information according to the ratio of the material of the lunch box A. For example, it is possible to calculate a list of used materials (individual product units at the stage of purchase) from the individual product ID list included in the evaluation aggregation information.

  For example, for the sake of simplicity, it is assumed that lunch box A is made from 10 kg of rice, 20 kg of water, 7 kg of pork, and 13 kg of onion. Ratings can be allocated to categories). Since the allocation is performed according to the product category, for example, if there are two suppliers who deliver pork, the redistribution may be determined by the distribution of the weight of the deliverables by each supplier. Here, it is assumed that the evaluation for the processor C1 itself is half, and the other half is distributed at 10: 20: 7: 13. That is, in this case, the reflection rate r_C1 = 0.5 for the processing of the processor C1 itself, the reflection rate r_P1 = 0.5 × 10/50 = 0.1 for the rice delivered by the producer P1, and the delivery of the producer P2 Reflection rate for water r_P2 = 0.5 × 20/50 = 0.2, Reflection rate for pork delivered by producer P3 r_P3 = 0.5 × 7/50 = 0.07, for onion delivered by producer P4 The reflection rate r_P4 = 0.5 × 13/50 = 0.13.

  Note that the redistribution method may be an average value distribution in addition to the above-described evaluation weight method. The distribution by the average value is, for example, an evaluation aggregation value (0 is a standard value) that is 1.2 after normalization according to the above reflection rate. For example, the evaluation aggregation value for the product category of 10 kg of rice is 1 .2 × 0.1 = 0.12 and the evaluation aggregation information with the evaluation aggregation value corrected to 0.12 is passed to the product category. On the other hand, the allocation by the evaluation amount is to distribute the evaluation weight in the evaluation aggregation information according to the above reflection rate. For example, the evaluation amount of 10 kg of rice in the lunch A for the evaluation aggregation information consisting of 200 evaluation information is 200 × 0.1 = 20. Further, as described above, it is possible to transmit the reflection rate as it is without calculating the redistribution.

  The redistributed evaluation aggregate information is passed to the transmission unit 34 in the form of (commodity category, evaluation aggregate information) for each product category in each material. Here, the individual product ID list (list) included in the evaluation aggregation information is, for example, a list of individual product IDs belonging to the product category among the materials used for the calculation at the time of redistribution.

  The transmission unit 34 displays a list of (product category, evaluation aggregation information) given to each supplier such as rice, water, pork, onion, etc. (transmission side supplier ID, product category, evaluation aggregation information) Send in the form.

  For example, as shown in FIG. 10, it is assumed that the evaluation weight m of the evaluation aggregate information is redistributed at the reflection rates r_C1, r_P1, r_P2, r_P3, and r_P4, respectively. When the evaluation aggregation information for the lunch A given from the retailer S1 is redistributed and transmitted to the rice H as the material of the lunch A to the producer side management system 4 related to the producer P1 The transmission data is (transmission side supplier ID, product category, evaluation aggregation information) = (C1, (P1, P1, H), (E, m · r_P1, list)), and the like. Similarly, for producers P2-P4, (C1, (P2, P2, I), (E, m · r_P2, list)), (C1, (P3, P3, J), (E, m · r_P3) , List)), (C1, (P4, P4, K), (E, m · r_P4, list)). The processing of the processor C1 itself is, for example, ((C1, C1, p_A), (E, m · r_S1, list)) (where p_A is the processing of the product with the type ID = A) ).

  Each of the producers P1 to P4 receives the information as described above from the receiving unit 41 of the producer-side management system 4 related to the product (for example, rice, It is possible to know what kind of evaluation is made by consumers for retail goods (for example, lunch box A) including water, pork and onion. In this way, for example, the correlation with the improvement of the production method is investigated, or the price, quality, and delivery amount are adjusted to the one with a particularly bad evaluation value among some of the processors that have been delivered. Can do.

  Next, an example of the effect obtained by the present embodiment will be described with reference to FIG.

  First, a case where an accident occurs at a specific retailer S1, a case where an accident occurs at a specific processor C2, and a case where an accident occurs at the producer P3 will be described. Here, accidents are assumed to be quality accidents such as the occurrence of food poisoning, but are not limited to these.

  For example, when there is an accident due to poor handling of a specific product (for example, lunch box A) of the retailer S1, the evaluation information notified from consumers a, b, etc., who purchased the specific product, The evaluation aggregate value of the evaluation aggregate information of the product category handled by the retailer S1 decreases. Here, when the abnormality detection mechanism of the aggregation processing unit 23 of the retailer-side management system 2 related to the retailer S1 detects the abnormality, for example, the processor C1 who is a supplier of the product of the product category has reduced the evaluation. The aggregate value is notified. At the same time, information can be transmitted to the manager of the retailer C1.

  In the above case, in the retailer-side management system 2 related to the other retailers S and the like, since the evaluation aggregate value does not vary greatly, the retailer-side management system 2 related to the other retailers S2 and the like. Since there is no accident report to the processor side management system 3 related to the processor C1, there is no significant fluctuation in the evaluation aggregate value observed in the processor side management system 3 related to the processor C1 on the delivery side. become.

  Next, for example, when the processor C2 has a cause of an accident, this has spread to all downstream (retailers S3, S4, etc. and consumers e to h, etc.), and the processor C2 has finally delivered. It is considered that the evaluation aggregate values related to all or some of the commodities notified from the retailers S3, S4, etc. are all reduced. In this case, an abnormality can be detected in the redistribution processing unit 33, the receiving unit 31 and the like of the processor side management system 3 related to the processor C2, and a prompt action can be taken.

  For example, the retailer S1 in FIG. 12 makes an inquiry to the upstream processor C1, the downstream retailer S2, and the like, and that no abnormality is detected by them (that is, the retailer S1 is the most upstream of abnormality detection). By knowing that there is something), it can be recognized or estimated that there is a cause of the abnormality. Further, for example, the retailers S3 and S4 in FIG. 12 make an inquiry to the upstream processor C2 and the downstream retailer S4 and the like, and that an abnormality is detected by them (that is, the retailer S3 and S4 in FIG. By knowing that it is not upstream, it is possible to recognize or presume that there is a cause of abnormality in the other person.

  Next, for example, consider a case where there is an accident at the producer P3. The producer P4 delivers to a plurality of suppliers including the processors C1 and C2. This spills over all downstream (processors c1, c2, etc., retailers S1-S4, etc. and consumers ah, etc.) and is eventually notified by the processors C1, C2, etc. delivered by the producer P3. It is thought that the evaluation aggregate value concerning all or a part of the products decreases all at once. In this case, an abnormality can be detected in the receiving unit 41 of the producer-side management system 4 related to the producer P3, and prompt action can be taken. Further, in the processor side management system 3 related to the processors C1 and C2, when the fluctuation of the evaluation aggregate value notified from the downstream is detected, the processors C1 and C2 may have a cause in themselves. By taking into account how each supplier P1, P3, etc. may change the evaluation aggregate value, taking into account cases that may cause the cause, It is also possible to identify the material that caused the accident.

  Next, an internal configuration example of the redistribution processing unit 33 of the processor side management system 3 will be described.

  FIG. 13 shows an internal configuration example of the redistribution processing unit 33.

  As shown in FIG. 13, the reallocation processing unit 33 includes a reallocation calculation unit 331 and a reallocation table 332.

  The redistribution table 332 is a table that records the correspondence between products and materials.

  The redistribution calculation unit 331 redistributes the evaluation aggregated information from the contents of the redistribution table 332 and the evaluation aggregated information received by the receiving unit 31 according to a predetermined method, and the evaluation aggregated information for each used material Is generated.

  As the redistribution table 332, for example, the following two forms or a mixed form thereof can be considered.

  FIG. 14A shows a first configuration example of the redistribution table 332.

  In this example, the redistribution table 332 is a table composed of two columns, and records one product in one row.

  In the first column, the individual product ID of the manufactured product is recorded alone.

  In the second column, a list of material IDs of the materials used for the product with the individual product ID is recorded. For example, this form is used when materials can be identified one by one (for example, industrial products). For example, taking a notebook personal computer as an example, a list of material IDs is (hard disk ID, liquid crystal panel ID, keyboard ID,...) And the like.

  FIG. 14B shows a second configuration example of the redistribution table 332.

  In this example, as in the first configuration example, the redistribution table 332 is a table composed of two columns, and records one product in one row.

  Further, as in the first configuration example, in the first column, the individual product ID of the manufactured product is recorded alone.

  The difference from the first configuration example is that a list of data sets of (material ID, usage ratio) is recorded in the second column. Here, the usage ratio is equal to usage / total amount. For example, this form is used for materials that may be partially used, such as paints and foods. In this case, the “total amount” of the material corresponding to the “material ID” is recorded and managed separately. Further, the first configuration example can be expressed by the second configuration example. For example, in the second configuration example, if the usage ratio in (material ID, usage ratio) is 1, it has the same meaning as the first configuration example.

  The redistribution calculation unit 331 checks the redistribution table 332 using the individual product ID included in the evaluation aggregate information obtained from the reception unit 31 as a key, and obtains a list of materials and a ratio of usage for each individual product ID. . Here, the evaluation aggregate information is redistributed to each material by using the ratio of the usage amount and the ratio bias described below.

  For the ratio bias, for example, one or more averages of the following forms are used according to the purpose. The form of ratio bias includes, for example, manual bias setting by an administrator (for example, in the case of a bento, increase the ratio of raw materials such as sugar beet that characterizes the bento), cost equivalent amount (use ratio, cost), weight Ratio (use ratio, total amount).

  For example, it is assumed that there is a lunch box made of 100 g of rice, 400 g of water (including those used in the process), 140 g of pork, and 65 g of onion. At this time, the calculation procedure using the ratio bias of the weight ratio and the manual bias setting will be described below. For manual bias setting, for example, rice: water: pork: 0: 5: 3. An example in which the evaluation aggregate value is 1.2 and the evaluation weight is 140 and the evaluation weight is distributed will be described.

  100 g of rice has a usage ratio of 0.01 when the incoming quantity is 10 kg. 400 g of water has a usage ratio of 0.02 when the incoming quantity is 20 kg. When 140 g of pork is received in 7 kg, the usage ratio is 0.02. When the amount of onion 65 g is 13 kg, the usage ratio is 0.005.

  This lunch box is entered in the redistribution table 332 as shown in FIG.

  From the reallocation calculation unit 331, the reallocation table 332, the individual item ID of the lunch box, and the total amount at the time of arrival regarding each material are known. From the material ID and usage ratio of each material, the weight ratio of each material used in the lunch box can be obtained as 100: 400: 140: 65. If the evaluation weight 140 is distributed according to this ratio, it becomes approximately 20: 79: 28: 13. Further, according to the manual bias setting, it becomes 28: 0: 70: 42. Due to the average of the two biases, the distribution of the evaluation weight for this lunch is approximately 24: 39.5: 49: 27.5.

  Actually, there may be a plurality of individual product IDs corresponding to certain evaluation aggregate information. In that case, the redistribution calculation unit 331 may be operated for each individual product ID, and redistribution may be performed by taking the average. Further, regarding the total amount of inspection, if it is difficult or wasteful from the viewpoint of calculation amount, an average may be taken after sampling a certain amount of products.

  Next, when the line for each product is clearly divided to some extent, such as in a factory (for example, when two types of products are rarely produced at the same facility at the same time), input to the redistribution table 332 The following means can also be used as the part.

  RFID readers, barcode readers, etc. are installed at the entrance and exit of the line, and other processes as necessary, and the correspondence between raw materials and products is recorded. At this time, the ID read (or given in some cases) at the line exit becomes the individual product ID of the product, and the ID read at the entrance or process is the material used for producing the individual product. Product ID. In addition, when it is difficult to determine how much each material is used by dividing a plurality of materials, the redistribution table 332 is assumed assuming that the materials are used equally for all the products. It may be generated.

  As described above, according to the present embodiment, evaluation information for an article on the consumer side can be used more effectively on the article providing side.

  In addition, evaluation information including defects and accidents on the consumer side can be reliably and quickly transmitted to contractors on the distribution channel for faster response to accidents, investigation of the cause of accidents, more detailed quality control, quality It is expected to contribute to improvement.
