Description

2890764 1

  Process of expertise of the completeness, the efficiency and the reliability of the system of traceability set up on an industrial site, in particular of the agro-alimentary sector.

  FIELD OF THE DISCLOSURE The field of the invention is that of the automatic monitoring, or traceability, of the products of the industrial sector and in particular the agri-food sector. More specifically, the invention relates to a process for assessing the completeness, efficiency and reliability of the traceability system set up on an industrial production site.

  2. Solutions of the Prior Art Traceability is a management tool that is now unavoidable in the supply chain, risks and quality in a company. The traceability system, which is based on a chain of hierarchical information, obviously contributes to the logistics organization and the quality approach of the company but also more and more to its forward-looking and commercial strategy.

  The list of products, mainly of industrial origin, whose life path monitoring is made mandatory by legal or normative provisions is constantly increasing in the world, especially in Europe and North America. This list of products still includes a majority of products from the pharmaceutical or agri-food sector. Other sensitive products, however, are referenced as, inter alia, car seats and boosters, blood derivatives or tires mounted on a motor vehicle, to which a unique identifier, issued in consultation between all the tire manufacturers, must be attributed, according to a recent legislative decision in the USA.

  In the agri-food sector, many food crises, particularly in France and Europe, triggered by listeriosis, the presence of salmonella or dioxins, have shown the difficulty for operators in the agri-food sector to control all the risks associated with food. way of life of a food product.

  It has also been found that it is very difficult, when a defective or at risk product is detected at any stage of its life path, to succeed in identifying, quickly and efficiently, all of the other products which have undergone, at least partially, the same treatment as the defective product, and which are therefore likely to have the same defect. However, in the case, for example, of a product contaminated with listeria, it is particularly important to be able to quickly remove from sale all other potentially contaminated products, so that they do not reach the product. consumer's plate. This safety issue also concerns the automotive industry in the event of failures of master mechanical parts of the braking or steering systems of a series of motor vehicles, the processing and storage of radioactive waste or the pharmaceutical sector. .

  The introduction of genetically modified organisms (GMOs) into the market, especially the cases of bovine spongiform encephalitis (BSE) that decimated European cattle farms, as well as the epidemic of bird flu in Europe. Asia, heighten consumer anxiety and heightened awareness among all stakeholders in the agri-food sector of the absolute need to put in place an effective system of complete traceability of food products, bringing together all the information related to the life of this product (creation, transformation, storage, etc ...) and which is completed at each passage of the product in a link in the production and distribution chain.

  A growing number of new regulatory requirements also reflect the demand on the part of companies and their economic fabric (customers, shareholders, bankers, suppliers, insurers, etc.) to secure process risks. traceability in the company. These laws, regulations, standards, or precautionary principles are mostly related to food safety (eg European Regulation 178/2002 or the Bioterrorism preparedness Act & Country-of-origin Labeling law), or to financial management (eg the Financial Security Act or Sarbanes Oxley Act).

  However, to date, there is no effective and reliable evaluation method for qualifying the traceability performance of an industrial production site, in particular food products, from supplier supply to distribution. manufactured products, whatever the industrial sector (agri-food, automobile, chemistry, pharmaceuticals, telecommunications, ...) 3. Objectives of the invention The invention aims in particular to provide an effective solution to the problem of the management of the traceability system of industrial products on a production site.

  More specifically, an objective of the invention is to provide a technique of expertise of the completeness, efficiency and reliability of the traceability system of an industrial site that is efficient and simple to implement.

  Another objective of the invention is to propose such a technique that can be used on any production site.

  The invention also aims to provide such a technique to eliminate or at least greatly reduce the risk of a deficiency in terms of delay in the process of identification, and withdrawal of all products deemed defective, or susceptible to present a risk to the safety or health of users.

  Yet another object of the invention is to propose such a technique which can enable the site management company to restructure and improve its traceability system while controlling the corresponding investment costs.

  Another objective of the invention is to enable the establishment of a recognized certification attesting to the quality of the organization of the traceability pole for an industrial production site.

  4. Essential features of the invention 2890764 4 These objectives, as well as others which will become apparent later, are achieved by means of a process for the control of the quality of products delivered by a production system, by monitoring the completeness, efficiency and reliability of a traceability system associated with the production system.

  According to the invention, such a control method comprises the following steps: determining a plurality of domains of said traceability system to be checked; determination for each of said domains of a plurality of criteria to be monitored, said criteria of a domain being correlated with each other; for each of said criteria, assigning a digital data representative of a quality value by measurement via at least one sensor and / or by evaluation; for each of said domains, multiplying all of said digital data of each of said criteria of said domain and applying a mathematical regression function to the resulting product to obtain a digital datum representative of a quality value of said domain; comparing, for each of said domains, said digital datum to at least one predetermined threshold; - issuing an alert and / or a stop command of said production system if at least one of said digital data of one of said domains is less than said predetermined threshold.

  Thus, the invention is based on a completely new and inventive approach to controlling the completeness and quality of traceability information on an industrial site. Indeed, the technique of the invention is based on a thorough technical expertise of the reliability, efficiency and completeness of the traceability system implemented on this site, which had never been considered in the past . Such a technique is based in particular on a division of the traceability system into a set of domains to be controlled, which are complementary to each other, and, within each of these domains, on the determination of a plurality of criteria to be met. monitor which are correlated to each other. This correlation allows the simple and precise attribution of a numerical data to each of the domains, representative of the quality level of this aspect of the traceability system, by multiplying notes assigned to each of the criteria of this domain.

  This provides an effective tool for evaluating the quality of the traceability system, which, in the event of a fault, makes it possible to directly control the shutdown of the production system, which constitutes a significant improvement over previous systems, in which the time elapsed between the detection of a defect on a product from the industrial site and the repatriation of all the lots likely to present the same defect could be particularly long. Thus the responsiveness of the company in case of anomaly is guaranteed by the implementation of the invention, through a regular update of the traceability information.

  Moreover, this tool makes it possible to reduce the number and the range of the products to be recalled in the event of an incident, in particular food, in the case where information relating to the lot numbers would not have been correctly recorded and / or preserved. Indeed, the invention makes possible a targeted identification of the products concerned.

  Advantageously, such a control method also comprises a step of generating a graphical representation of said digital data of each of said domains in the form of a rosette.

  Preferably, said regression function is chosen so that said predetermined threshold coincides with the midpoint of a corresponding branch of said rosette.

  Thus the company has a tool to directly visualize the performance of its traceability system.

  According to an advantageous technique of the invention, such a control method further comprises a step of comparing said generated rosette with a predetermined minimum rosette, and, depending on the result of said comparison, a step of issuing a label of certification of said traceability system or a step of issuing said alert or said stop command of said production system.

  It is thus possible to envisage a generalization of the certification label to a set of sites or companies and an updated communication of the sites referenced to the public by various media (web, ...) for a better information of the consumer.

  On the other hand, the company has a retroactive control tool for its industrial site. Indeed, the actors of the site, having read the alert, can then take the necessary steps to restore the performance of the traceability system.

  Preferably, said domains of said traceability system belong to the group comprising: - quality of information necessary to establish a complete map of activity of said production system; - completeness of the information related to the traceability system; - adequacy of said traceability system and operating processes of said production system; - evaluation of the reliability of the traceability system; - coding of said products in accordance with at least one coding standard applicable to said production system; - availability of information and products; adequacy of said traceability system and at least one risk management use relating to a sector of activity of said production system; extending said traceability system out of said production system into a chain perimeter; - Implementation in said production system of at least one traceability procedure and at least one staff training plan of said production system to said procedure.

  2890764 7 Thus, all the information necessary for evaluating the performance of the traceability system of an industrial site is exhaustively gathered.

  According to an advantageous characteristic of the invention, said step of assigning a digital data item to each of said criteria is performed after a matrix analysis of said traceability system, and said numerical data item assigned to each of said criteria is value in a set of four predetermined numerical constants according to whether said criterion is: - in accordance with a predetermined reference criterion; - not in accordance with said predetermined and high-level reference criterion; - not in accordance with the said predetermined and moderate reference criterion; - not in accordance with said predetermined and low-importance reference criterion.

  Thus, the manager of the company responsible for improving the traceability system has a hierarchical analysis of the potential actions to be undertaken as part of the traceability activity. The application of the invention thus constitutes an appreciable aid in the decision-making process.

  Preferably, said digital constants belong to the set (1; 0.01; 0.7; 0.9).

  According to an advantageous technique of the invention, for a domain, said predetermined threshold S is defined by S = fp, q ((3Pyq), where p is the number of criteria of moderate importance of said domain, q is the number of criteria of low importance of said domain, fp, q is said mathematical regression function, (3 is the value of the numerical data assigned to a criterion of moderate importance and y is the value of the numerical data assigned to a criterion of importance Advantageously, where a is the value of the numerical data assigned to a criterion of high importance, the largest numerical value such that 0 <a <(3 <y <1 and a <(3Pyq for all values) is given to a. (3 and y.

  In an advantageous embodiment of the invention, the application of said mathematical regression function fp, q to 1, respectively to (3Pyq, corresponds to a predetermined scale factor, to one half of said factor of ladder.

  Preferably, said scale factor is substantially equal to 100.

  Advantageously, in said step of comparing said rosette generated to a predetermined minimum rosette, only the criteria of high importance are taken into account.

  In fact, the expectations and constraints of the various industrial players will differ according to their sectors of activity and the size of the site. It is therefore important that they have a reliable, immediately available indicator that respects their specificities.

  The invention also relates to a system for controlling the quality of products delivered by a production system, by monitoring the completeness, efficiency and reliability of a traceability system associated with said production system, comprising means for: - determining a plurality of domains of said traceability system to be checked; determination for each of said domains of a plurality of criteria to be monitored, said criteria of a domain being correlated with each other; for each of said criteria, assigning a digital data representative of a quality value by measurement via at least one sensor and / or by evaluation; for each of said domains, multiplying all of said digital data of each of said criteria of said domain and applying a mathematical regression function to the resulting product to obtain a digital datum representative of a quality value of said domain; comparing, for each of said domains, said digital datum with at least one predetermined threshold; - issuing an alert and / or a stop command of said production system if at least one of said digital data of one of said domains is less than said predetermined threshold.

  Similarly, the invention covers a computer program product downloadable from a communication network and / or stored on a computer readable medium and / or executable by a microprocessor, comprising program code instructions for the implementation of process steps of quality control of products.

  6. DESCRIPTION OF AN EMBODIMENT OF THE INVENTION The general principle of the invention rests on the implementation of an expert method for efficient and reliable measurement of completeness, efficiency and reliability. a traceability system adapted to any industrial site.

  This original method is based on a matrix analysis of the site traceability activity, taking into account the tracing interventions associated with the elementary production subprocesses, the quality control procedure, and the logistics follow-up.

  In order to be able to apply the method according to the invention to any type of industrial site, the inventors have defined the characteristics of a standard referencing tool or standard site. Such a standard site has all the general characteristics of a production site, without exception, and has a traceability system that is ideally organized and is therefore flawless at all levels.

  A traceability system is ideally organized around four main operational axes: The management of information unlikely to evolve in the short or medium term in relation to the flow of products or by-products, the organization of production , the tracing of materials, the system put in place for the identification of products and the tracing of information, the system for managing links between the identifiers of the products; - the management of traceability operations that must be coordinated over time with production and which concerns the data entry, the dynamic capture of links, the archiving of information, their security and the control of access to information; Management of the information system; - The management of identified risks.

  In addition, such a traceability system can adapt to a rapid evolution of production patterns.

  The measurement of the completeness and the performances of the traceability system is elaborated by means of a grid of criteria organized around nine themes, also called domains. For a satisfactory implementation of the method, a preliminary survey, in the form of a questionnaire, must be conducted with qualified staff of the site, in order to collect unambiguous answers validating or not validating or partially validating the criteria.

  A specific algorithm for processing all the criteria makes it possible to quantify the quality of the traceability system, set up on the site to be evaluated, by comparison with the standard site.

  The segmentation into nine themes makes it possible to identify the most critical measures to implement, to forecast the cost of interventions and to plan a schedule. In this sense the invention is a technical decision tool. According to this problem, a natural evolution of the invention may be to become the tool for awarding a label.

  In addition, the invention can make it possible to prioritize the site on a network scale, in order to participate in the estimation of the economic profitability of the site and in the reduction of operating costs.

  Furthermore, an application of the invention consists in installing on the site an indicator screen for displaying and monitoring the daily evolution of the performance of the traceability system from the evaluation parameters defined according to the invention.

  The criteria are formed on a single model and belong to the group of questions aiming at answering the two questions of the form: Is there on the industrial site an action, a procedure, a document, information on the document, information? following a precise format on the document? - Has the company set up a procedure, a systematic action? The answers to these questions are analyzed to determine whether the criterion is fully compliant or not. In the case where the question relates to a countable set of processes, procedures or actions, a criterion verified only by a part of this set is considered as non-compliant. On the other hand, according to the technique of the invention, each criterion is assigned a degree of importance, more generally called importance, which can be considered as high, moderate or low.

  Thus, the invention is based on a completely new and complete approach to managing traceability procedures. The invention provides professionals with an expertise tool of the traceability system that is efficient because it is simple to implement. In relation with FIG. 1, a synoptic diagram of the characteristics and organization of the physical flows and the traceability system of a reference industrial site in its environment is presented.

  The upstream organization of the site includes the suppliers of raw material 101 and processed materials 102 as well as consumables (maintenance and maintenance products ...) 103 as well as the logistics transport 104 of these products to the production site. On the site, the physical flows 105a to 105f of the materials (displacement from one station to another, transformation or assimilation of a material) are directed according to the order of the manufacturing steps 106a to 106e and interfere with the recycling steps. or scrapping 108. Analyzes are performed from the samples of materials taken from the production line on site or in laboratories 109. The finished product 110 is packaged and / or conditioned by a dedicated unit 111 before it leaves the production line. site to be transported (carrier 112) to customers' distribution or production sites 113. The returned products 114 or the unsold inventory 115 are managed by the logistics unit 116.

  The traceability system is deployed at all levels and relies on information carriers such as vouchers or cards 117, labels 118, the traceability-quality file 119 which groups all the information concerning the chain of custody and quality analyzes carried out on raw materials, semi-finished products or finished products and computer resources 120 for managing and archiving data related to traceability.

  For a standard site, all the interventions on the products (change of place, unusual events (breakdowns, ...) or malfunctions) are recorded on these supports so as to constitute a complete and secure information system. One-to-one links 121, represented by double arrows, designate the self-checking operations on the critical points, which are represented by flags 122. These operations, combined with a systematized procedure for preserving documents on different supports, and adapted security, ensure a reliable reliability of the traceability system.

  FIG. 2 shows the organization of the characteristic criteria of the invention around the nine themes constituting domains of the traceability system that should be monitored.

  Theme 21 includes the criteria relating to all the information needed to establish a complete map of the site's activity: criterion 211 aims to verify whether there is a cartography (synoptic, complete and functional representation) manufacturing and including at least the steps of the procedures and their duration, the food and non-food raw materials, the intermediate products and the finished product, the recycled products, the waste, the consumer units, the packaging and shipping units; - criterion 212 aims to determine whether there is a mapping of the traceability system both upstream of the production site (relations with the supplier), on the production site and downstream of the site (delivery to the customer) which include at least a description of the functional steps and the lots including the definition of all the products concerned, the step or steps preceding their creation, the link of descent of a lot with parent and child lots, and specifying the identifiers, the codifications and the material support and the corresponding location; the purpose of criterion 213 is to determine whether there is a description of the content of the traceabilityquality dossiers by type of finished product, including all the physico-chemical and microbiological analyzes carried out on the finished product and the materials used in the manufacture of the finished product; the purpose of criterion 214 is to verify whether there is a document explaining the operation of the reconstitution of all the lots associated with the production of a finished product; Criterion 215 aims to verify whether there is a cartography of computer tools, and marking or reading devices used; criterion 216 aims to verify whether there are specifications on the functioning of traceability in computer systems; criterion 217 is intended to verify whether there is a description of the traceability device in terms of subprocesses for each step which includes at least the information concerning: - the batch number generation inputs and outputs; the means for capturing batch numbers (bar code, radio frequency identification (RFID), paper capture, label, electronic data interchange protocol or EDI, electronic mail, fax, telephone, etc.); - computer applications or paper documents containing the information; - treatments and controls; - data transmissions; - the profiles of the persons authorized to seize; - authorization means (access rights); - the place of seizure; - the place of storage; - the moment of storage; - the moment of use in the return of the information (request traceability); - the person responsible for the storage; the authorization means (access rights, physical security, locking mechanism); - the event triggering the seizure.

  Theme 22 groups together the criteria relating to the comprehensiveness of the information related to the traceability process: the criterion 221 aims to check if the receipt / delivery notes of the suppliers (/ addressed to the customers) contain the information relating to the identification of the supplier / customer, the nature of the products, the date of transaction / delivery that the competent authorities must have; the purpose of criterion 222 is to determine whether the supplier's (/ customer's) receipt / delivery receipt contains information on more detailed product information, quantities and lot numbers to be retained; criterion 223 aims to verify whether the receipt / delivery notes of the suppliers (/ addressed to the customers) contain the information relating to the carriers; Criterion 224 aims to determine whether there is at the manufacturing level a record of information relating to raw materials, primary or incorporated raw materials (ME), and products in process, manufacturing stages, manufacturing; - criterion 225 aims to verify whether the company ensures the traceability of recycled products; criterion 226 aims to verify whether the company ensures traceability of co-products, and repackaging; criterion 227 aims to determine if the company ensures the recording of the information relating to the shipment: date, customer, address, name of the product, code, deadline of optimal use of the products (DLIU), date of conservation (DLC), quantity, date of manufacture, batch number of pallets, carriers, truck number.

  Theme 23 gathers the criteria concerning the adequacy of the traceability system with the operational process. In fact, the company must check the consistency between the traceability information returned by the traceability system and the manufacturing or process procedure, and in particular: criterion 231 aims to verify whether the traceability system put in place takes into account the uncertainties of manufacture (breakdown, resumption of production), the recycling of material during the process, the dates of cleaning of the apparatus and the machines for the delimitation of the perimeter of return of batch, the units of expedition reconstituted, the interventions of replacement of cartons on pallets, unsold returns, by-products, reintroduction of products into the process due to a lack of bagging; the criterion 232 aims to verify if the traceability-quality file contains the certificates of analysis on the raw materials and the finished or semi-finished products, the certificates of analysis of the water, the sheets of control, the documents of maintenance and cleaning; criterion 233 aims to determine whether there is a synchronization of the information flow with the physical flow of the products; criterion 234 is intended to determine whether the enterprise ensures the consistency of the traceability system and in particular that the uniqueness of the identifiers or batch numbers is effective, that the identification of the parent or child batches is one-to-one, that there is a one-to-one correspondence between the documents in the traceability-quality dossier and the adjoining entity via the lot number or other information, that the entities or lots drawn consist of products whose production and / or transport conditions are identical, that the uniqueness of the sequential parcel number (SSCC) is guaranteed as well as the registration of the one-to-one descent of the shipping units in case of multiple supply points in a just-in-time (picking) or sets consisting of heterogeneous units.

  Theme 24 groups together the criteria involved in the evaluation of the reliability of traceability procedures. Criterion 241 aims to determine whether there are efficient procedures concerning the self-checking established for the critical points related to the capture, the modification and the return of batch numbers and links between batch numbers, in particular concerning the management of incidents, errors in data entry and retrieval by computer interfacing batch numbers of raw material, and the absence of a lot number to receipt of the raw material; - criterion 242 aims to verify whether there are efficient labeling procedures and in particular whether the logistic labels and in particular the labels developed following the standards of the associations EAN (international association of article numbering) and UCC (advice for the standardization of codes) are correctly set and the labels pre-printed on the raw material are in conformity; Criterion 243 seeks to determine whether there are procedures for defining and controlling rights of access to documents and computer systems; Criterion 244 aims to determine whether the specifications specifying the conversion and data transfer protection procedures between software packages include a description of the technical standards in force, the reciprocal responsibilities of the software in terms of data loss, the protection device data and in particular the locking system for sensitive information and special controls (cryptographic keys ...).

  Theme 25 groups together the criteria relating to the codification of products according to the respect of the standards and in particular: criterion 251 aims at checking if the standards EAN and EAN UCC are used relative to the labeling of the logistic units (pallets, cardboard), l identification of the main functional locations, and the coding of raw materials and inputs to be plotted.

  Theme 26 groups together the criteria relating to the availability of information and products: - criterion 261 aims to determine whether the company carries out a test of computer media by simulation of an operation (restoration, criterion 262 aims to check whether the company is carrying out a double measurement of the time required for the collection or identification of finished products in the chronological order of product development, by carrying out a search operation of a set of products packaged on pallet from their batch number and the internal batch numbers of finished products from a batch number of raw material or batch number of packaging material, the purpose of criterion 263 is to determine whether the The company performs a double measurement of the time required to collect or identify finished products in the reverse chronological order of the product development process. an identification or recovery operation for the raw materials used from a batch number of the finished product, all the information in the document map and all the batch supplier numbers and internal batches of raw material concerned from a batch number of raw material; criterion 264 aims to determine whether the company ensures that the shelf life of each type of information is greater than the shelf life or the best-before date of the products, in accordance with the legislation or legal recommendations.

  Theme 27 groups together the criteria relating to the adequacy of the traceability system with the risk management practices relating to the sector of activity of the site, and in particular: criterion 271 aims to determine whether the company has assessed withdrawal costs following a problem detected on a lot of raw material from a supplier or internal; criterion 272 aims to verify whether there is a match between the fineness of the traceability procedure and the food risks at each traceability node; criterion 273 is to determine whether the company has taken into account the allergenic risk and the risk associated with the presence of GMOs.

  Criteria 272 and 273 are obviously only relevant for the agri-food sector. 1.0

  Theme 28 groups the criteria for extending the off-site traceability system in the chain of custody: criterion 281 aims to determine whether the company ensures that suppliers comply with a quality assurance plan that it has approved by ordering an annual audit by means of a spot check or inspection of the logistic traceability parameters, ensuring that the contracts of the suppliers of the materials involved in the product and service development contain the information specifying: - the name of the raw material; - the lot number (training procedure, codification) and its location on the product and the accompanying documents; - definition of the batch (content, quantities); - the conditions of archiving and access to the accompanying document; - the periodicity of the traceability tests.

  criterion 282 is to determine whether the material supplier's contract includes the manufacturing process diagram and the accompanying document.

  Theme 29 groups together the criteria relating to the establishment of traceability procedures and personnel training plan for these procedures, and in particular: criterion 291 aims to verify whether there is a traceability action at each stage of the procedure manufacturing or packaging; criterion 292 aims to determine whether there are self-checking procedures for each critical point and in particular for: i. the labeling of raw / processed materials and logistic relabelling EAN UCC in the event of an incident; ii. the use of raw materials in bulk; iii. recycling of products during manufacture; iv. the reporting of a malfunction and incident management (the error recovery and recovery procedure in the manufacture of the product) and / or in the event of software failure; v. the management of the product recall; vi. management of batch purposes, unsold returns, waste, unsold and withdrawals; vii. the appointment, appointment or feedback of staff and / or external stakeholders (audit) and / or suppliers and / or customers in the quality traceability activity; viii. archiving.

  criterion 293 aims to determine whether there is a training plan for all site staff when introducing new software or marking and / or reading material and a plan for others novelties for handling or logistics personnel.

  It is noted that the degree of importance, or the importance, attributed to all of the preceding characteristic criteria relating to themes 21 to 29 is high. FIG. 3A illustrates the calculation algorithm assigning, for each theme, a global value 301 which makes it possible to assess the degree of perfection or imperfection of the traceability system. For each corresponding criterion 310, the algorithm assigns the constant 320 and vice versa, if the criterion 310 is not in conformity, a constant at 330, 340 or y 350 if the degree of importance of the criterion is respectively high, moderate or low. . The value of the constants at 330, R 340 or y 350 is attached to each of the themes and can thus vary between two different themes. It should be noted that in most situations in which the invention is implemented, the value of the constants at 330, (3,340 and 350) remains unchanged for all the topics.

  For each theme, a plurality of additional criteria may be added to the characteristic criteria described in the invention, on the express condition that these criteria have an incidence correlated with that of the characteristic criteria within this theme.

  In a preferred embodiment of the invention, the constant 320 is equal to one, and the results of studies have shown that the constants at 330, (3 340 and y 350 must take the values one hundredth, seven tenths and nine tenths respectively. More generally, the technique of the invention recommends choosing the constants a 330, 13 340 and y 350 for a thematic so that: the constants at 330, (3 340 and y 350 are strictly between zero and one and that the constant y 350 is strictly greater than the constant (3340, itself strictly greater than the constant a 330.

  the constant a 330 remains lower than the product of any constant (3,340 brought to the power p with any constant y 350 raised to the power q with p and q respectively the total number of criteria of moderate and low importance for this topic .

  The global value 301 is the digital image by a mathematical function fp, q of the value obtained by forming the product of all the constants (320 or 330 or 340 or 350) allocated to each criterion. The mathematical function fp, q, depending on the pair (p, q) for each theme, can be a linear, polynomial, logarithmic or exponential regression, defined such that the application of fp, q to 1 and to (3Pyq respectively corresponds to a value 360, also called scale factor, and half of this value 360. In this preferred embodiment of the invention, the value 360 is equal to one hundred.

  In a second embodiment of the invention, the criteria 221, 222, and 223 (renamed respectively 2213, 2223, 2233) relate exclusively to the receipt vouchers, an additional criterion 228 groups together the characteristics of these same criteria for the vouchers only. and criterion 224 is broken down into four separate criteria for registration: information on raw materials and primary manufactured materials (criterion 2240, - information on products in process (criterion 2242); manufacturing (criterion 2243), manufacturing hazards (criterion 2244).

  In this same embodiment, the criterion 226 is replaced by two criteria 226, and 2262 such that the criterion 226 relates exclusively to the traceability of the by-products and the criterion 2262 relates exclusively to the traceability of the repackings.

  In this second embodiment, the degree of importance of the criteria 2213, 2241, 2242, 2243, 2244, 2261 and 228 is high, the degree of importance of the criteria 2223 and 2262 is moderate and that of the criteria 2233 is low.

  In a third embodiment, the criterion 241 is declined according to four new criteria 241 ,, 2412, 2413 and 2414 aiming at determining whether there are self-monitoring procedures, relating to risk management, effective and reliable for each number. batch allocated during the manufacturing procedure in a unique way. These criteria concern, respectively, the risks associated with the capture of information (criterion 2411), the risks related to the return of information (criterion 2412), the risks associated with the modification and / or the deletion of information. (criterion 2413) and the risks attached to identifying links between two lots. In this third embodiment, the criteria 2411, 2412 and 2414 are of high importance and the criterion 2413 is of moderate importance.

  Naturally, the invention also relates to any other embodiment implementing a decomposition of the criteria stated for the preferential embodiment into subcriteria, the degree of importance of which can be weighted with respect to the initial criterion to take account of the specificities site, industry, customers or suppliers.

  In a fourth embodiment of the invention, a second value 302 justifies the attribution of the traceability certificate and the consumer label, if it 2890764 24 reaches a threshold value 303 for each theme. This value 302, whose allocation method is illustrated in FIG. 3B, is calculated on the basis of only the criteria having a high degree of importance. It is obtained by forming the image by the function fp, q of the numerical result of the multiplication with each other of the values of the set of constants (320 or 330), obtained for each of the criteria of degree of importance. high.

  The value 303 also corresponds, according to the technique of the invention, to the image by the function fp, q of the product of ((3) p with (y) q, where p and q respectively denote the total number of criteria of moderate and low importance for the subject concerned.

  An application of the invention is now presented to an industrial bakery site for the manufacture of breads for making sandwiches for fast-food restaurants.

  FIG. 4A illustrates a decomposition into subprocesses of the upstream stages of preparation of the raw materials, called milling steps, from the receipt of wheat to the delivery of the flour to the mill for an industrial bakery product production site, under Synoptic diagram form. It is recalled that this operation is necessary to accurately determine the performance of the traceability system relating to themes 21 to 24.

  It is also recalled that, in a general sense, a process is defined as a sequence of tasks, manual, semi-automatic, automatic, contributing to the elaboration, production or processing of information, products or services. In the sense of the invention, of course we consider the only processes contributing directly or indirectly to the production of logistical or qualitative traceability information. In practice, a sub-process is associated with each manufacturing step (intervention on the material, change of batch number).

  In a first step, the wheat is delivered by five farmers on the receiving platform of the site and stored in five specific silos. The reception and storage operations of each of these sources of raw material are referenced respectively by the sub-processes 401a to 401e and 402a to 403e.

  After receiving an ordering instruction, the wheat is transferred to secondary transit silos. The contents of the silos 402a, 402b, as well as a part of the silo 403c, are grouped in a first secondary silo according to the sub-process 403a, the other part of the silo 403c is transferred to a second secondary silo according to the sub-process 403b and the contents of silos 402d and 402e are combined in a third secondary silo during subprocess 403c. The wheat from the secondary silos is then spread over four cars, following the processes 404a to 404d and conveyed to the mill during the subprocess 405a. In a second step, the wheat is unloaded to a silo according to subprocess 406a. Other quantities of wheat from other sources of supply follow a process identical to that of the first stage and are stored in other silos near the mill in subprocess 406b at 406m before moving to a mill. central mixer (subprocess 407) fed by all silos. The mixture precedes the wheat milling operation or subprocess 408. The resulting flour is then distributed to two storage silos during subprocesses 408a and 408b. A co-product, called bran, is obtained at the end of this process and is packaged to be sold as a food supplement for livestock. Next are the subprocesses of receiving a 409 command and transporting to the factory 410.

  The following steps concern the processes, not detailed, of manufacturing in the plant: incorporation of raw materials in bulk and pallet to form the leaven 411, kneading 412, pointing step 413 during which the leaven rests, shaping 414, cooking 415 , primer or lining 416, bagging 417, palletized 418.

  Figures 4B to 4E illustrate the details of the organization of the collection and processing of traceability information within subprocesses 411, 412, 416 and 418.

  Within subprocess 411 (FIG. 4B), three pieces of information 420, 421, 422 are entered at the raw material management application level 423 before being exported to the database management application 424. traceability (traceability-quality file and corresponding computer application).

  Information 420 and 421 correspond respectively to the wheat flour lot number entered on the supplier's delivery order which will be used for inventory management, and to the same batch number which will be transmitted at the level of the kneading sub-process 412 , detailed figure 4C. Information 422 concerns the absence of GMOs on the certificate of analysis for soya flour.

  A control operation 425 of the batch number of wheat flour entered at the kneading level with respect to the list of lot numbers entered at the logistics level is carried out by the application 423. This last operation constitutes the critical point attached to the Subprocess 411, for which a self-check procedure has been set up, by the management software, the uniqueness of the assigned lot number and the conformity of the lot number entered at the kneading.

  In sub-process 412 (FIG. 4C), three pieces of information 430, 431 and 432 are entered at the level of the traceability management application 433. The item 430 relates to the start time of the kneading operation read. on the clock of the kneader and the information 431 and 432 respectively correspond to the recording of the numbers of the silos (431) containing the wheat flour, the soya flour and the sugar read on a screen automaton, and the number of the tanks (432) containing yeast and oil, read on a second PLC screen. The information 430 is processed and is validated by software dedicated to the application 433. The critical point attached to this sub-process is the control of the chronology of the hours 430 indicated for each kneading sequence in relation to the numbering of the batches. concerned and overall timing control of the site clocks, attached to the manufacturing process or internal to the hardware. The company has set up a 434 self-monitoring procedure related to this critical point.

  Subprocess 416 (Fig. 4D) which is attached to the bread surface lining with sesame seeds has two input operations 440 and 441, a control operation 442 and two validation operations 443 and 444 as illustrated. Figure 4D. The information 440 relates to the batch number of the sesame bags on the supplier's delivery note and the information 441 corresponds to the time of use of a lot of sesame, which is read on a specific clock. Operation 442 for checking the correspondence between the sesame batch numbers entered on the delivery note of the supplier and the bakery receipt form on which the batch number of sesame is entered by a bakery operator has been identified as a point critical for this sub-process. At the level of the accounting department, a first automatic control procedure makes it possible to ensure the conformity of each sesame lot number, by comparison of the supplier delivery note with the bakery receipt form, and a second automatic control procedure allows to to verify the uniqueness of the number of each lot, by analyzing the accounting information concerning the relationship of the lot of sesame with the previous and following lot numbers. The information 440 and 441 are then validated and recorded on a computer support in the operations 443 and 444. The information entered 450, processed 451 or exported to the database 452 in the subprocess 418 is shown schematically in FIG. 4E.

  The information 450 relates to the pallet number assigned automatically when creating a new pallet, and transmitted to the computer database dedicated to the management of the pallets 452, to be exported to the database (the computer management of the pallet). traceability 453. An analysis of the error logs published during the export procedure of the database 451 is carried out systematically to detect the non-unique lot numbers, and on the other hand, a self-checking procedure is validated at the installation of the software for the management of the databases 452 and 453. This procedure consists in verifying that the event corresponding to the generation of two labels with the same batch number can not occur and that test data export correctly between the 452 pallet management computer database and the 453 traceability computer management database.

  FIG. 5 illustrates the second embodiment from the theme relating to the criteria for evaluating the completeness of the information for the industrial bakery site.

  On the site, the management responsible for the traceability activities sent a questionnaire to the competent staff who collected information concerning the contents of the 501 receipt, the 502 delivery note, the documents relating to the follow-up of the production 503 and recycled products 504, cards carrying the co-products 505 and the repackaging of the products 506, and documents relating to the shipment of the products 507. This department will then be able to evaluate the performance of its traceability system concerning the completeness of the products. information. For this it applies the criteria 221 to 228 of the invention. The latter notes that the 501 receipt forms do not mention the lot number of the suppliers who delivered their bulk production without specifying the origin of the growing areas. Management therefore maintains that Criteria 2213 and 2233 are in conformity and that Criterion 2223 is inconsistent and associates values 521, 522 and 523 respectively with 320, 340 and 320, since Criterion 2223 is of degree of moderate importance. Management then notes from the questionnaire that all

  The information available on the delivery notes 502 and in relation to criterion 228 is compliant, and therefore allocates the value 320 to the result 528. It also notes that the information relating to the batch numbers used in the kneading step 412 does not appear. 503. The values 320, 330, 320 and 320 are assigned to the numerical data 5241, 5242, 5243 and 5244, and thus the product of the four preceding values to the overall value 524 corresponding to the criterion 224. In addition, the replies to the questionnaire indicate that the layout of the recycled products is ensured and therefore the value 320 is assigned to the numerical value 525 in accordance with criterion 225.

  The questionnaire allows the management to validate that the layout of the reconditioned products is ensured, and that, on the other hand, during the shaping and cutting stage, the excess dough remained stuck to the vat is not reincorporated to the dough. but are used to make co-products. The values 330 and 320 are thus assigned to the data 5261 and 5262. On the other hand, the shipping documents containing all the information required by the criterion 227, the value 320 is thus given to the data 527.

  It will be recalled that in the preferred embodiment the coefficients one hundredth, seven tenths and nine tenths are assigned to the values a 330, (3,340 and y 350, and that the coefficient 360 has a value of 100. The result of the evaluation is ten and a half (or 10.5) for the information completeness theme, with reference to a standard site for which the result is worth one hundred, which is therefore unsatisfactory. decision making process towards the most appropriate measures to improve the collection of traceability information.

  It is now presented, in connection with Figure 6, a graphical representation of the result of the expertise of the traceability system according to the invention in the form of a rosette. The rose window has nine branches corresponding to characteristic themes 21 to 29, and graduated on a scale of zero to one hundred.

  This presentation advantageously makes it possible to monitor the traceability system in a syncretic manner. For the sake of readability, the condition of attribution of the label corresponds to half of the value 360 for each theme, so that this condition coincides with a regular enneagon. The values 302, results of the evaluation of the performance of each theme, are carried on each branch of the rosette and are connected by a broken curve in dashed lines. For the embodiment of FIG. 6, the function fpq, associated with a branch of the rosette, is a linear regression that associates with any variable x the result fp, q (x) = (value 360) (x / (2 (1- (3pyq)) + ((3pyq-1/2) / (13pyq-1)).
