Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a specification creation device and a specification creation method effective when planning a new product.

[0002]

2. Description of the Related Art Conventionally, products are produced and sold to satisfy the price, quality, time and the like requested by customers through stages of basic research, product planning, development, design, trial manufacture, evaluation, and the like. . In recent years, shorter product cycles, more sophisticated product functions,
In particular, the demand for cost reduction suggests the importance of studying up to the design stage together with the improvement of production technology.

[0003] Design is performed based on product specifications, and the product specifications are created in accordance with the planning of a new product. FIG. 8 is a flowchart showing a flow up to the design stage in a general production system when a new product is produced.

In step S1, a concept for product planning is formulated. In other words, the person in charge of product planning envisions the functions required for a new product, and details specific product characteristics (hereinafter referred to as product specifications) indicating the characteristics of the product necessary to satisfy the functions and quality. Envision).

In the next step S2, the person in charge of product planning prepares a product specification based on the concept in step S1. Next, a system is designed based on the created product specification. In the system design in step S3, the product design is divided into an electrical system and a mechanical system, and the product design is distributed to the electrical design department and the like for the electrical system and to the mechanical design department and the like for the mechanical system. ing.

Steps S4 to S6 show the design of the mechanical system, and steps S7 to S8 show the design of the electric system. The person in charge of each design department performs mechanical design or electric design in steps S4 and S7, respectively, with reference to the product specification of the part in charge. Next, in steps S5 and S8, each section manager performs a trial production based on the design values.
The product characteristics of the prototype are evaluated in steps S6 and S9. If it is determined that the evaluation result of the prototype does not satisfy the characteristics required by the product specification in charge, the process returns to steps S4 and S7 to correct the mechanical design and electrical design.

[0007] In this way, the evaluation result is fed back to the next design, and the design is repeated for each design department until the requirements of the assigned product specification are satisfied.

When the result of the evaluation of each design department satisfies the requirement of the product specification in the part in charge, the whole product is evaluated in the next step S10. If it is determined that the evaluation result of the entire product with respect to the prototype does not satisfy the characteristics required in the product specification, the processing is performed in step S3.
And modify the system design.

Thus, the evaluation result of step S10 is fed back to the next system design, and the processing of steps S3 to S10 is repeated until the requirements of the product specification are satisfied.

When the evaluation result of the entire product satisfies the requirements of the product specification, in the next step S11, a production design for producing the product is performed.

As described above, in the design stage, not only a design is made for each department, but also a prototype and an evaluation of the prototype are performed based on the design values. If the evaluation result does not satisfy the requirements based on the product specification, it is necessary to redesign. Furthermore, even during redesign, it is necessary to perform trial manufacture and evaluation, and the time and cost spent on design and development are extremely likely to be enormous.

In addition, with the diversification and complexity of products,
Since the design is performed separately for each section, it is necessary to evaluate the entire product after the evaluation for each section. Therefore, even after a prototype that satisfies the requirements for each department is created, if the evaluation of the entire product does not satisfy the requirements, it is necessary to correct the entire system design again. In this case, the design of each department is also revised again, and the design period and cost are remarkably increased.

[0013]

As described above, conventionally, in the development of a new product, there has been a problem that the time and cost required for the design stage become enormous. There is also a problem that a product that does not satisfy the customer's request may be developed.

[0024]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a flowchart showing one embodiment of a specification creating method according to the present invention.

In the present embodiment, the information relating to the product characteristic items and the product specifications is automated by making a database of necessary information at the stage of the product planning concept. By creating a database for determining product specifications using information on existing products, the basis of the product specifications is clarified, and the target value is set to an appropriate value.

Further, using a predicted value of a product specification based on a design proposal, it is determined whether or not a design satisfying a target product specification is possible, and a product specification is prepared.

That is, first, in step S21 of FIG. 1, a list of product qualities and functions according to customer requirements is created. The customer required quality list 2 is collected and created for the quality of the product, and is expressed in customer terms such as "the image is beautiful" and "portable". The product function list 3 is collected and created for the functions of the product, and is provided in accordance with the basic functions required for the product, such as "playable video" and "playable TV", and according to customer requirements. It contains information about the product request function to be added.

In the next step S22, an input operation for inputting the contents of these lists 2 and 3 as customer request information is performed. The input customer request information is stored in a RAM (not shown).

In the next step S23, a search is made for a product characteristic item indicating the characteristic of the product necessary to satisfy the quality and function of the product indicated by the customer request information. The product characteristic items are stored, for example, on a hard disk or the like, and are searched by step S24, which is an access process for the product characteristic files A, B, and C. FIG. 1 shows only three types of product characteristic files A, B, and C to simplify the description.

FIG. 2 is an explanatory diagram for explaining the product characteristic file in FIG.

The product characteristic file A contains the items of the product characteristic for the quality requirement of “easy to carry”, and the product characteristic file B contains the product characteristics for the quality of “clean image”. The item has contents, and the product characteristic file C is “good sound”.
Each item of product characteristics for quality is the content.

For example, as shown in FIG. 2, the content of the product characteristic file A can be a weight, a size, a reproduction time and the like, and the content of the product characteristic file B can be a resolution and a screen size. For example, information indicating whether an average product specification (quality), a sufficiently high product specification, or a low product specification is expected for each characteristic item is also added to the product characteristic file. . The information to be added to the product characteristic item is not limited to three levels, and may be classified in a predetermined numerical range in a stepwise manner, or may be non-stepwise information such as expecting a high product specification as much as possible. It may be. The hard disk or the like stores product characteristic files corresponding to customer request information in various possible expressions.

In step S23, a search for the product characteristic files A, B, and C is performed by inputting customer request information as a keyword. For example, when the operator inputs a keyword “image is beautiful” using a keyboard or the like (not shown),
The product characteristic items such as the resolution and the screen size, which are the contents of the product characteristic file B, are obtained as search results together with information indicating expected product specifications.

In FIG. 2, the product characteristic files A,
B and C correspond to the types of customer request information, respectively. For example, as shown in FIG. 3, only two product characteristic files A and B are provided. The indicated keywords may be stored in association with the numbers, and the product characteristic file B may store the product characteristic items corresponding to the numbers of the respective keywords. In this case, by using these numbers and performing mapping in accordance with the search condition, it is possible to obtain information indicating product characteristic items and expected product specifications.

In step S24, a product characteristic item is displayed as a search result. The product characteristic items of the target product are
For example, it can be displayed by an output device such as a monitor. Instead of using all the retrieved product characteristic items, for example, the product characteristic items are arranged in an order according to importance, and the product characteristic items are automatically selected according to the number of items from the top. Alternatively, if the number of items is less than the specified value, the search for the product characteristic items may be repeated again.

In the next step S26, it is determined whether or not a product characteristic item exists as a search result. Step S26
If it is determined that the product characteristic item has not been searched, the process proceeds to step S27, and a warning display is displayed. In this case, the operator operates a keyboard or the like (not shown) to add new product characteristic items to the product characteristic files A, B,
By adding to C, the database may be updated.

If it is determined in step S26 that the product characteristic item exists, the process proceeds to step S28. Step S28 is a procedure for creating data of the final product characteristic item of the target product after the selection and addition processing. For example, according to this procedure, it is also possible to add weights according to the importance to the retrieved product characteristic items.

As described above, the product characteristic items are made into a database as a product characteristic file in correspondence with the customer request information, and a search is performed by using a keyword that specifically expresses the customer request, thereby almost automatically generating the expectation of the target product. It is possible to extract a product characteristic item including information on a product specification to be performed.

The next step S29 is a procedure for searching for product information. This step S29 searches for product information by step S30, which is a process for accessing the product information file.

FIG. 4 is an explanatory diagram showing the specific contents of the product information file 4 in FIG. As shown in FIG. 4, the product information file 4 stores a product name (T500) of a ready-made product, a product characteristic item of the product, and specific product specifications as product information. The product information file includes product information on a large number of ready-made products.

In step S29, a product information file is searched by inputting a target item characteristic item including expected product specification information as a keyword. For example, in step S29, a search is automatically performed based on the data created in step S28. In this case, a similar product characteristic item of a similar product or a product having a similar part based on the product function list 3 created for the target product is to be searched. In step S29, the product specifications of such corresponding product characteristic items are extracted within the range of expected product specifications.
Obtain as search results.

For example, if product information is to be searched for a video-incorporated television receiver which is a composite product, video and television receivers are considered as similar products, and the corresponding product characteristic items of these ready-made products are considered. The product specification is obtained as a search result.

In step S31, a target product specification which is a target value of the product specification to be set is determined based on the search result obtained in step S29. Step S32
Is a procedure for creating product specification target data indicating the target value of the product specification. To create the product specification target data, the product function list 3, product characteristic items, and target product specifications are used. The contents of the created product specification target data can be displayed on a monitor or the like.

As described above, a large number of ready-made product specifications are made into a database as a product information file corresponding to the product characteristic items, and a search is performed using the product characteristic items. Obtainable.

In the next step S33, one of a plurality of design plans is selected. Step S34 is processing for accessing a predicted value file storing predicted values of various product specifications for each design plan. A plurality of design plans (three design plans A, B, and C in FIG. 1) are created by existing parts or existing design methods, and are obtained when the design is performed for each design plan. Predicted values of product specifications are expected.

In step S33, the predicted value file is read out, and the target product specification of each item given by the product specification target data obtained in step S32 is sequentially compared with the predicted value of each design plan, thereby obtaining the target product specification. The design plan having the closest product specification is selected as the optimum design plan. In this case, using the importance evaluation result of the product characteristic item, the higher the importance of the product characteristic item,
A method of selecting a design plan that is close to the target product specification may be used.

In the next step S35, it is determined whether or not each predicted value of the selected design plan satisfies the product specification target data. If all the predicted values satisfy the target product specifications given by the product specification target data, the process shifts to step S36; otherwise, the process returns to step S33.

In step S35, if the predicted values of all items satisfy the target product specifications, the target product specifications are set as the product specifications. Step S36,
This is the procedure for creating a product specification. In step S36,
Create a product specification using the product specification target data.

If it is determined in step S35 that all the predicted values do not satisfy the target product specifications, a design plan is selected again in step S33. Step S35 is executed again on the selected design plan, and the selection process of step S33 is repeated until the condition in step S35 is satisfied.

The product specification created in step S36 can be displayed and output on a monitor or a printer, for example.

FIG. 5 is a block diagram showing a hardware configuration for realizing the product specification creating method of FIG.

The user interface 11 includes a keyboard, a monitor, and the like (not shown), and functions as an interface between a microcomputer (hereinafter, referred to as a microcomputer) 12 and a user. The user interface 11 enables input of customer request information in step S22 of FIG. 1, display of product characteristic items in step S24, display based on product specification target data, and the like.

The microcomputer 12 includes an input data judgment unit 13, a calculation unit 14, and a control unit 15. The input data determination unit 13 receives data from the user interface 11 and determines the content of the user's input processing.
The judgment result of the input data judgment unit 13 is supplied to the control unit 15.

The control unit 15 has a work RAM 16 and controls the arithmetic unit 14 to perform a series of processes shown in FIG. That is, the control unit 15 controls the reading and writing of the product characteristic items with respect to the customer request information, and also controls the reading of the design proposal. Further, the control unit 15 determines a target product specification in step S31. .

The calculation unit 14 performs various calculations under the control of the control unit 15. For example, the calculation unit 14 can perform a comparison operation between the predicted value of the selected design plan and the target product specification, that is, a comparison calculation for executing the processing in step S35.

The control unit 15 sends and receives data to and from an external storage device such as a hard disk via the external storage control unit 17. The external storage control unit 17 is configured to be able to access the product characteristic file 18, the product information file 19, and the predicted value file 20. That is, the external storage control unit 17 can realize the access processing of steps S24, S30, and S34 in FIG.

Next, the operation of the embodiment configured as described above will be described.

Now, for a new product, it is assumed that the customer specifies that image projection and sound output are possible as basic product functions, and that it is required to be easily portable and have a high quality of beautiful images. These requirements are put together in a customer required quality list 2 and a product function list 3 in step S21 of FIG.

In the next step S22, the operator enters the state shown in FIG.
For example, the user operates the keyboard of the user interface 11 to input customer request information based on the lists 2 and 3.
This customer request information is input to the input data determination unit 13 of the microcomputer 12.
Supplied to The input data determination unit 13 determines that the input is customer input information, and supplies the input customer request information to the control unit 15 in order to search for a product characteristic item. The customer request information is stored in the RAM 16.

The control unit 15 searches for a product characteristic item in step S23. That is, the control unit 15 is an external storage control unit.
17 is controlled to access the product characteristic file 18 (step S24). As customer request information, keywords such as "images and sounds appear", "portable", and "images are beautiful" are input. From the product characteristic file 18,
For example, weight (g) (small), size (inch)
Product characteristic items such as (small), reproduction time (medium), resolution (high), and audio output power (medium) are read.

In step S 24, the control unit creates display data of the retrieved product characteristic item and outputs it to the user interface 11. Thereby, the product characteristic items including the expected product specifications are displayed on the monitor.

Next, the process moves from step S26 to step S28. In step S28, the control unit 15 creates data of the product characteristic item of the target product. In this case, for example, sorting may be performed in order of importance.

In step S29, the control unit 15 controls the external storage control unit 17 to search the product information file 19 by using a product characteristic item including an expected product specification as a keyword. In this case, the control unit 15 searches for a product having a similar part of a similar product, and extracts a product characteristic item corresponding to a product which is within an expected product specification range. Thus, the product specification of the product characteristic item of the ready-made product is obtained as a search result.

In the next step S31, the control unit 15 selects the product specifications of a large number of products by considering the importance of the components, the importance of the parts to be used, the time required for production, and the like. To determine the target product specification of the product.

In step S32, the control unit 15 creates product specification target data, which is target data of a product specification, using the product function list 3, product characteristic items, and target product specifications. The control unit 15 can also create display data based on the product specification target data and supply it to the user interface 11 to display the data on a monitor or the like.

As described above, the product characteristic items corresponding to the customer request information are stored in a database, and the product information of the existing products corresponding to the product characteristic items is stored in the database, so that the product specification of the new product corresponding to the customer request can be obtained. Target data can be easily obtained.

In the next step S33, the control section 15 controls the external storage control section 17 to search for a predicted value file (step S34). The predicted value file has a plurality of design plans, and each design plan includes information on predicted values of product specifications. The control unit 15 selects a design plan that satisfies the target product specification by sequentially comparing the predicted value of each design plan with the target product specification.

In step S35, the control section 15
Using 14, it is determined whether or not all of the predicted values of the selected design plan satisfy the target product specification. If all of the predicted values do not satisfy the target product specifications, the process returns to step S33, and the control unit 15 selects a design plan again.

If it is determined in step S35 that all the predicted values satisfy the target product specifications, the process proceeds to step S36, where the control unit 15 completes the product specification target data as a product specification. . The display data of the created product specification is supplied to the user interface 11 by the control unit 15, and is displayed on the screen.

As described above, in the present embodiment, a database of the product characteristic items and product information makes it possible to easily create a target product specification for a customer request. In addition, a file is prepared in which a plurality of design plans and predicted values of product specifications that will be obtained when the design plans are used are prepared in advance, and when the selected design plan is used, the predicted values correspond to the target product specifications. After confirming that they are satisfied, they create product specifications. Therefore, when designing based on the created product specifications, it is possible to prevent the evaluation of the prototype from being bad and prevent the design from being changed, and to significantly reduce the period and cost at the design stage. it can.

FIG. 6 is a flowchart showing another embodiment of the present invention. 6, the same steps as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.

This embodiment differs from the embodiment of FIG. 1 in that a procedure of step S37 is added. Step S37 is a procedure for correcting the selected design plan. If it is determined in step S35 that all the predicted values do not satisfy the target product specifications, the design plan selected in step S37 is corrected. In this case, automatic correction is performed for the product characteristic items that do not satisfy the target product specifications.

For the revised design plan, a predicted value of the product specification is obtained. When the process in step S37 ends, step S35 is executed again, and the process in step S37 is repeated until the condition in step S35 is satisfied.

In the embodiment configured as described above, the control unit 15 determines that all the predicted values do not satisfy the target product specifications by the comparison operation in step S35 using the operation unit 14. In step S,
Move to 37. In step S37, the control unit 15 corrects a design related to a product characteristic item that does not satisfy the target product specification using a predetermined method. The control unit 15 obtains a predicted value of the product specification that can be obtained also for the modified design plan.

Next, the process of step S35 is executed again. The design modification in step S37 is repeated until all the predicted values satisfy the target product specifications in step S35.

Other functions are the same as those of the embodiment shown in FIG.

FIG. 7 is a flowchart showing another embodiment of the present invention. In FIG. 7, the same steps as those in FIG.

This embodiment is different from the embodiment shown in FIG. 1 in that steps S41 to S45 are added. In step S41, not only a customer required quality list and a product function list are created, but also an importance evaluation result is created. The importance evaluation result is obtained by performing the importance evaluation on the customer request information by a questionnaire method, an AHP (analysis hierarchy process) method, a conjoint analysis method, or the like.

A step S42 is provided next to the creation of the product characteristic item data in the step S28. In step S42, the importance evaluation result of the customer request information is converted into the importance of the product characteristic item by a known quality development method or the like.

Step S for Determining Target Product Specifications
Subsequent to 31, a step S43 is provided. Step S43 is
This is a procedure for correcting the target product specification, in which the target product specification is corrected according to the level of the importance evaluation result of the product characteristic item. For example, in step S43, the target product specifications are redefined such that the target product specifications are set high for the product characteristic items with high importance.

Step S44 and step S45 are provided as one branch of the judgment in step S35. Step S44 is a procedure for determining whether or not correction of the target product specification is possible when all of the predicted values do not satisfy the target product specification. Whether or not the correction is possible is determined according to the importance of the corresponding product characteristic item. If the correction is possible, the process proceeds to step S45; otherwise, the process proceeds to step S33. Transition.

Step S45 is a procedure for correcting the target product specification. After this procedure, the process shifts to step S35 again.

It is apparent that step S37 of FIG. 6 may be provided after step S44, and the process may return from step S37 to step S33.

Next, the operation of the embodiment configured as described above will be described.

In step S41, a customer required quality list, a product function list, and an importance evaluation result are created.
By entering customer request information as a keyword,
The search and display of product characteristic items are performed in steps S22 to S27, and the product characteristic item data of the target product is created in step S28, as in the embodiment of FIG.

In the present embodiment, the next step S
At 42, the product characteristic items of the target product are ranked according to their importance. In step S29, a search for product information is performed using the product characteristic item as a keyword. In the next step S31, a target product specification is determined. Next, in step S43, the target product specification is corrected according to the importance of the product characteristic item.

In this series of processing, step S42
The target product specifications are determined in accordance with the importance of the target product characteristic item determined in. For example, for a product characteristic item with high importance, the product specification of a product that was a popular product among existing products is obtained as a search result at the time of product information search, and for a product characteristic item with low importance, the product characteristic Obtain product specifications of products whose items are not important as search results.

Thus, by steps S31 and S43,
A target product specification corresponding to the importance of the product characteristic item is determined and corrected. As a result, the target product specifications
It will be more responsive to customer requirements.

At steps S32 and S33, similarly to the embodiment of FIG. 1, target data of product specifications is created based on target product specifications, and a design plan is selected. In the present embodiment, if it is determined in step S35 that all of the target values do not satisfy the target product specifications, the process proceeds to step S44.
In step S44, it is determined whether the target product specification can be corrected.

For example, if the predicted value that does not satisfy the target product specification is for a product characteristic item of relatively low importance, the target product specification may be corrected. In this case, the target product specification is corrected to be low in the next step S45. The predicted value and the target product specification are compared again in step S35 using the corrected target product specification.

If it is determined in step S44 that the target product specification cannot be corrected,
The process returns to step S33 and the selection of the design plan is repeated as in the embodiment of FIG.

As described above, in the present embodiment, the same effects as those of the embodiment of FIG. 1 can be obtained, and a product specification in accordance with a customer's request can be created. It is possible to prevent the design from becoming difficult by setting the product specifications more than necessary.
