The supplier submits sample parts, inspection data of the parts, and manufacturing process condition data to the purchasing company in order to undergo the certification test of the purchasing company. The purchasing company confirms the submission from the supplier and makes a certification decision. Regarding part specifications, part samples are inspected and tested, and it is determined whether part functions and performances satisfy the standards specified by the purchasing company for them. In addition, regarding the manufacturing process of parts, manufacturing process conditions (ie,
Confirm the conditions of the process for manufacturing the part sample that satisfies the part specification qualification standard, and determine whether or not the process is controlled so as to always ensure the quality that satisfies the qualification standard. If the certification test is passed (that is, “certified”), the parts, that is, the product can be traded between the purchasing company and the supplier.

[0006] In a small-scale production, a maker or the like who mainly orders custom products to suppliers, regularly certifies the manufacturing process of suppliers who have already passed the certification, and renews the certification. There are many manufacturers. This regular certification renewal method is
After receiving the manufacturing process condition data from the supplier, the person in charge of procurement goes to the manufacturing process of the supplier to evaluate the manufacturing process condition, performs the certification examination based on the evaluation result data, and notifies the supplier of the certification result. To do.

A method for evaluating and estimating the quality of a product such as a work defect rate of a product manufactured by a series of manufacturing operations in a manufacturing workplace related to the present invention is disclosed in Japanese Patent Laid-Open No. 2001-2001.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a system and method for certifying a factory using a network according to the present invention will be specifically described with reference to the drawings.

The system for certifying a factory using the network according to the present invention is a specification of a part, a product or a material (a part, a product or a material is hereinafter referred to as a product) necessary for the qualification provided by a procurement company. Also, through a network from suppliers (certified plants), we obtain manufacturing process condition information consisting of "quality", "technology", "price", "delivery date", "points pointed out at the time of the last certification", and factory level actual data regarding manufacturing. It automatically performs the certification examination and sends the certification judgment result to the supplier through the network.

The system for performing factory certification according to the present invention is
In particular, the procurement company is to re-certify the supplier (certified factory) and check the results on the network. Perhaps for the first factory certification, the procurement company needs to go to the supplier and investigate the correspondence between the supplier-supplied evaluation data for factory certification and the actual on-site evaluation value. , I think it is difficult to do everything on the network. Therefore, the system for performing factory certification according to the present invention on a network includes periodic re-certification, re-certification due to changes in manufacturing process conditions on the supplier side, and re-certification due to product specification changes on the procurement side, and Applies to the performance checks needed to recertify.

As described above, according to the factory certification on the network, the procurement side company can eliminate the necessity of going to the supplier for the factory certification evaluation, and when the supplier changes the manufacturing process condition, for example, It is possible to do this by performing only the factory certification evaluation corresponding to the changed part.

Further, when the supplier voluntarily updates the manufacturing process conditions or changes the manufacturing process management system, the supplier exchanges information with the certification system 11 on the procurement side to update the certification and update the certification history information. There is a need to.

FIG. 2 shows the outline of the configuration of the procurement system (buyer) authorization system 11 according to the present invention. The certification system 11 of the procurement company has the following configuration. (1) By providing at least a storage device (a server for storing the last certification condition information and the last achievement check condition information on the procurement side) 111 for storing the last certification condition information and the last achievement check condition information (certification history information) of the supplier. To be realized. The information stored in the storage device 111 is preferably information that can be shared with the supplier. (2) The storage device 111 that stores the certification standard information and the workplace standard actual value judgment standard information stores the certification standard information and the workplace standard actual value judgment standard information when the buyer carries out the certification and performance check examination / judgment. is doing. The contents store items common to each supplier and certification standard items for each supplier or for each manufacturing process of the supplier. Basically, it is necessary to save at least the certification standard information used at the previous certification and the factory level actual value judgment standard information used at the previous performance check. However, regarding the process change in the supplier that occurred after the last certification update, the approval of the buyer is approved every time the change occurs, and the certification standard information and factory level actual value judgment standard information are updated each time, and the certification and performance check history is updated. Store as information.

That is, as the certification information database 30 stored in the storage device 111, the certification standard 41 arranged by the procurement company (buyer) after agreement with the supplier, the certification result 44 certified last time, and the certification result last time At this time, the supplier submitted (recorded) the factory evaluation results (answers for each question item (certified evaluation item) shown in Fig. 6) and the factory-level actual value judgment criteria (Fig. 6) agreed upon by the supplier.
Is a criterion that is determined by determining the answer level for each question item, and is specifically indicated by using the in-process total defective rate calculated from the quality comprehensive index obtained from each of the above answer levels. For example, the calculated in-process total defect rate is 200p
In pm, if the factory level actual value check is OK up to a range of 10% before and after that, the factory level actual value determination criterion is
200 ± 20 ppm) and the result check result checked at the time of the previous result check (whether the total defective rate in the manufacturing process satisfies the factory level actual value judgment standard),
Factory level performance value submitted by the supplier at the time of the performance check (in-process total defective rate indicating the factory level calculated based on the data related to the quality of the product inspected or measured by an actual inspection device or measurement device), It will consist of the voluntary factory improvement record submitted by the supplier. (3) When the certification is updated, the manufacturing information (information necessary for certifying the factory evaluation result such as the manufacturing specifications and management contents) that is stored in the storage device 121 of the supplier system 12 and that includes the certification evaluation items is stored in the network 15 An input unit (information communication unit) 1 that is obtained via the Internet and stored in the storage unit 111f
Have twelve. Further, at the time of performance check, manufacturing information stored in the storage device 121 of the supplier's system 12 (information necessary for performance check such as factory level performance value including manufacturing specification and manufacturing management content, and voluntary factory improvement performance)
Is obtained via the network 15 and is stored in the storage unit 111e.
And an input unit (information communication means) 112 for storing the data. (4) The evaluation calculation unit 113a including the evaluation program for evaluating the manufacturing information consisting of the supplier's accredited evaluation items received at the time of recertification and at the time of performance check is compared with the accreditation criteria of the supplier and the evaluation result to determine whether or not the accreditation is successful. It has an accreditation and performance check examination / judgment unit 113 composed of a computer having an accreditation pass / fail judgment unit 113b.

Here, in the qualification and performance check examination / judgment unit 113, it is important that the answer to the qualification evaluation item provided by the supplier is credible or not. It is necessary to evaluate by referring to the certification information or the actual result data when the actual result is checked before or the actual delivery data of the product delivered to the buyer (for example, defective delivery rate). In short, if the answer to the certified evaluation item provided by the supplier can be relied upon, the evaluation should be made based on the answer. (5) It has a material system 114 for instructing suppliers to carry out transaction suspension processing and factory improvement when the certification judgment result and the performance check judgment in the certification pass / fail judgment unit 113b are unsuccessful.

The supplier system 12 collects information from the manufacturing line 123 and information from the purchased products 124, and based on the collected information, manufacturing process specifications and manufacturing process management contents. It is configured by a computer that creates (information necessary for certification such as evaluation result at the time of previous factory certification, and information necessary for performance check such as factory level actual value and voluntary factory improvement result) and stores it in the database 121. The manufacturing information processing unit 122 is included.

Next, a schematic processing flow in the buyer authorization system 11 according to the present invention will be described with reference to FIG.

First, the communication unit 116 shown in FIG. 4 obtains the submission data for the certification renewal inspection from the supplier, that is, the manufacturing process condition information (the level of each certification and performance check / judgment item described above) ( Step S31). Then, the evaluation calculation unit 113a of the qualification and performance check examination / judgment unit 113 evaluates and certifies the following items by the evaluation calculation program based on the input manufacturing process condition information (step S32). (A) Factory certification is possible by evaluating the ability of the manufacturing factory. As the ability of this manufacturing plant,
As described in 001-100838, "defect occurrence suppression power (defect build-up prevention power)" x "defect detection power" x "defect occurrence coping power" as the difficulty of causing defects in manufacturing plants. Can be expressed as “Defective occurrence suppression power” is the power of a manufacturing factory (supplier) that does not manufacture defective products. "Defective detection power" is a manufacturing factory (supplier) that can detect (extract) defective products so that they will not be sent from the manufacturing factory (supplier) to subsequent buyers.
Power of. The "defect handling capability" is the power of a manufacturing factory (supplier) that shortens the defect handling time as much as possible to prevent defective products when defective products occur.

Therefore, as shown in FIG. 6, based on the response from the supplier for each horizontal item, "defective occurrence suppressing power" x "defective detection power" x "defect handling in the vertical manufacturing standard work" By calculating "power" and performing comprehensive quality evaluation, it is possible to evaluate the ability of the manufacturing plant.

Therefore, the evaluation calculation unit 113a indicates that the supplier's A: quality, particularly, the manufacturing process management (manufacturing process management (A
-1: Manufacturing process control)), A-2: Quality improvement plan, A-
3: Evaluate the level of in-manufacturing process / delivery quality status, etc. That is, A-1: manufacturing process control is performed by the supplier,
Whether the product has been manufactured and inspected and delivered under the same manufacturing process conditions (including inspection conditions) as when the product or material specifications were certified ("A-1-
"1: Manufacturing process management status", "A-1-2: Manufacturing process worker, jig and tool management status", "A-1-3: Manufacturing physical environment", "A-1-4: Manufacturing history management ”,“ A
"1-5: Inventory management of parts (including components and finished products)", "A-
1-6: Management of prevention of mixture of foreign substances, "A-1-7: Confirmation of effects after process improvement", "A-1-8: Grasp of process capability and its utilization", "A-1-9: Shipping inspection ”). Specifically, as shown in FIG. 6, the manufacturing process management (A-1: manufacturing) in which the supplier is manufactured and inspected under the same manufacturing process conditions as the manufacturing process conditions (including inspection conditions) at the time of approval. The level of (process control) will be evaluated based on the response from the supplier (step S321).

By the way, in FIG. 6, the evaluation calculation count / constant database 4 shown in FIG. 4 is defined as follows.
It is assumed that 0 is stored in the storage unit 111c. (1) The questions regarding the quality of 21 items are each given a maximum of 5 points. This is the case where the relative weighting factors are the same for each question item (each certification evaluation item), and in reality,
A relative weighting coefficient may be set for each question item. (2) For an ideal factory, all items shall be answered with 5 points. In practice, the five points may be multiplied by the relative weighting factor. Of course, even in the case of an ideal factory, if the products are multiplied by the relative weighting factors, all the items will not be full marks. (3) For the worst factory, all items shall be answered with 0 point. In practice, the zero point may be multiplied by the relative weighting coefficient. (4) The weight of each force is “×”, “△”, “○”,
"◎" means "x" = 0 points, "△" = 1 point, "○" = 2
Points, “⊚” = 3 points.

By the way, for each question item (each certified evaluation item) which is a horizontal item shown in FIG. 6, the points of "defective defect prevention power", "defective detection power", and "defect occurrence coping power" are as follows: It is assumed to be predetermined.

That is, "manufacturing process control status (process abnormality,
"A product abnormality can be detected, and the processing rules are clearly defined)" is "defective detection power" and "defect occurrence coping power"
By assigning the most influence to, the score was set to “⊚” = 3 points, and the influence to the “defect build-up prevention power” was hardly affected, and the score was set to “x” = 0 point.

"Manufacturing process workers, jigs and tools, and measuring instrument management (management by qualified personnel is sufficient)" has the greatest effect on "defective in-building prevention power", and "◎" = 3 points. By assigning a score of 2 and influencing the "defect detection power" second, "○" = 2 points, and by affecting the "defect occurrence coping power" third, "△" = The score is 1 point.

The "manufacturing physical environment (physical environment in which it is easy to manufacture)" has the greatest effect on the "defect making prevention power".
By assigning a second effect to, "○" = 2 points, and by affecting the "defect occurrence coping ability" third, "△" = 1 point.

"Manufacturing history management (manufacturing history is systematized and traceable)" gives the most influence on "defect occurrence coping power", so that "◎" = 3 points, and "defect detection""○" = 2 by secondly affecting "power"
By assigning points as points and having almost no effect on the "ability to prevent defect creation," we assigned points as "x" = 0 points.

Further, as shown in FIG. 6, points are assigned according to the degree of influence on each small item or middle item.

Next, a method of calculating the quality score of the "defect making prevention power", the "defect detection power quality score" and the "defect occurrence coping power" will be described. The method of calculating the quality score of the “defect making prevention power” is to multiply by the number of answer points of each question item (actually, the product is multiplied by the relative weighting coefficient) and total the results over all items. In the case of the table shown in FIG. 6, "defective build-up prevention power" has a perfect score of 1
There are a total of 141 points for 80 points (ideal factory). The calculation method of the quality score of "Quality score of defect detection power" is also
Similarly, the answer points of each question item (actually multiplied by the relative weighting coefficient) are multiplied and summed over all items. In the case of the table shown in FIG. 6, the "defective detection power" is a total of 112 points with respect to a maximum of 140 points (ideal factory). Similarly, in the method of calculating the quality score of the "defect occurrence coping ability", the answer score of each question item (actually, a relative weighting coefficient is multiplied) is multiplied and summed over all items.
In the case of the table shown in FIG. 6, the “defect occurrence coping power” is 84 points in total with respect to 100 points (ideal factory).

As described above, the quality scores for the three capabilities are 141 points for, 112 points for, and 84 points for.

The total quality score is 337 points, which is the sum of the above points, and 420 points (perfect factory).

From the above, the certification pass judging section 113b is
It is judged whether the management level of the manufacturing process evaluated as a comprehensive quality score satisfies the standard value set by the accredited company. If it is satisfied, the management level (quality) of the manufacturing process is certified. If it is judged as acceptable, and if it is not satisfied, it is judged as unacceptable with respect to the management level (quality) of the manufacturing process.
(Step S322). (B) In addition to the above, the evaluation calculation unit 113a estimates a defect rate (per manufacturing process / total) that occurs in the manufacturing process of the supplier (step S321). Specifically, the “defective rate (total) in the manufacturing process” that is provided as an inspection result of the manufacturing process conditions of parts, products or materials from the supplier may be estimated and evaluated based on the above comprehensive quality score. It will be possible. That is, as shown in FIG. 6, the total quality score is 42, which is a total of 42
When 0 point is set to 100 points, it becomes 80 points, and it becomes possible to estimate and evaluate the defective rate (total) in the manufacturing process at the factory to be 23.8 ppm. Of course, by calculating the quality score for each manufacturing process, it is possible to estimate and evaluate the "in-process defect rate for each manufacturing process".

Further, the evaluation calculation section 113a can estimate and evaluate the "delivery defect rate" as a part, product or material when delivered to the buyer in the manufacturing factory as follows. That is, if the ratio of the past actual value in the manufacturing plant and the estimated in-process defect rate (total) at that time is obtained in advance, the estimated estimated in-process defect rate (total) It is possible to estimate and evaluate the delivery defect rate by multiplying the ratio obtained in advance at the manufacturing plant. Further, the evaluation calculation unit 113a compares the estimated delivery failure rate with the actual delivery failure rate, which is the result of actual delivery to the buyer and inspection, and if a significant difference is observed, the estimation delivery failure rate is estimated. It is necessary to multiply the formula for calculating the delivery defect rate by a correction so as to match the actual defect rate as much as possible. By doing so, it is possible to ensure the delivery failure rate estimated based on the failure rate in the manufacturing process step provided by the supplier. As for the defective delivery rate, the defective rate in the manufacturing process step received from the supplier may be associated with the defective delivery rate as a result of actual delivery to the buyer and inspection.

As described above, it becomes possible to estimate and evaluate the defect rate in the supplier.

Then, the certification pass judging unit 113b judges whether or not the estimated delivery defect rate satisfies the reference value set by the certified company, and when it is satisfied, the delivery failure rate is certified pass. If it is not satisfied, it is determined that the defective delivery rate is unacceptable (step S
322). (C) Furthermore, as an index calculated by the evaluation calculation unit 113a for evaluating the ability of the manufacturing factory for factory certification, as shown in FIG. 6, the response from the supplier (as a major item, "A: Quality, B: technology, C: price, D: delivery date, etc.). In “A: Quality” which is a major item, the score as the level of the manufacturing process management (manufacturing process management) is, for example, the middle item “A-1: Manufacturing process management” in the horizontal items shown in FIG.
"30 points" will be obtained by aggregating the answers from the suppliers. Furthermore, in "A: Quality", a score of "5" was obtained as the level of "A-2: Quality improvement plan", and as a level of "A-3: Manufacturing process / delivery quality status""11points" is obtained,
......, "A-9: Responsiveness at the time of failure occurrence and investigation request"
A score of "5" will be obtained as the standard of.

Next, with regard to "B: Technology", which is a major item, the score is "8 points" by evaluating product development ability, production technology ability, document management such as drawing management, management of parts purchase specifications, and the like. Is obtained.

The major item "C: Price" is evaluated by price competitiveness (price level, degree of achievement of required price, presentation of future price), VEC proposal ability, response responsiveness, etc. You get 8 points.

Regarding "D: delivery date", which is a major item, a score of "10 points" is obtained by evaluating delivery date response responsiveness, inquiry response, delivery date change response, production capacity, and the like.

By summing up these scores, "112 points" is obtained as the total score in the manufacturing plant.
In practice, the response from the supplier may be multiplied by the relative weighting coefficient not only for each small item but also for each medium item. In this way, by multiplying by the relative weighting coefficient, it means that even an ideal factory does not have a maximum of 5 points depending on the item.

Then, the certification pass judging section 113b judges whether or not the calculated total score satisfies the reference value set by the certified company, and when it is satisfied, the total score is judged to be certified pass. However, if they are not satisfied, it is determined that the overall score is unacceptable (step S32).
2). (D) Furthermore, the certification pass / fail judgment unit 113b simply calculates the total score based on the answers from the suppliers, the “defect occurrence suppression power (defect creation prevention power)”, the “defect detection power”,
A comprehensive evaluation of quality and an estimated total failure rate, which are expressed in "Countermeasures when defects occur," are used to quantitatively evaluate the ability of the manufacturing plant, and if they meet the respective standard values set by the buyer, they are judged to have passed the certification. If not satisfied, it is determined that the certification has failed (step S322). In particular, the certification pass / fail judgment unit 1
13b is a comprehensive score for each large item, each middle item, or each manufacturing process, and "defective occurrence suppressing power (defective built-in preventing power)" x "defective detecting power" x "defective occurrence coping power" It is possible to evaluate the defect rate based on the quality evaluation represented by “”, and when the standard value is not satisfied, the buyer can make an improvement proposal to the supplier.

Then, if the total score and the total quality evaluation and the estimated total defective rate satisfy the respective reference values set by the buyer, it is judged as certified pass, and if they are not satisfied, it is judged as certified fail (( Step S322).

As described above, the buyer system 1
The No. 1 accreditation and performance check examination / judgment unit 113 transmits the accreditation pass / fail judgment result and the performance check judgment result determined by the certification pass judgment unit 113b to the supplier via the network 15 via the material system 114 (step S33). .

Next, the quality calculation program in which the buyer system 11 evaluates the manufacturing process management (manufacturing process management) level of the supplier will be specifically described.

The quality / technology / price / delivery date calculation program according to the present invention is installed and used in a computer which is a buyer certification system 11. When the quality / technology / price / delivery date calculation program according to the present invention is installed, the quality / technology / price / delivery date calculation program has an apparatus configuration as shown in FIG. 4 as an evaluation apparatus (certification system 11). . That is, the certification system 11
Is a storage unit that stores a communication unit 116 that transmits / receives manufacturing process condition information, qualification determination result information, and the like to the supplier's system 12 via the Internet 15, a computer 113 that constitutes the qualification examination / determination unit, and a qualification standard information database. A storage unit 111 including a unit 111a, a storage unit 111b that stores an evaluation calculation program and a determination program, and a storage unit 111c that stores a database of evaluation calculation coefficients / constant data, and a computer 11
Various data in 3 (specification data of procurement parts, products, etc.)
And an input unit 112 for inputting information (certification standard information, etc.),
Output device (display device) 11 for displaying and outputting coefficient / constant data for evaluation calculation, various evaluation results, authorization judgment results, etc.
5 and. The computer 113 has a CPU 32 and R
OM31, RAM33, interface 34,
It is composed of a bus 35 connecting these.

The quality / technology / price / delivery calculation program according to the present invention is a “factory quality calculation program” for evaluating the ability level of a supplier (supply side company) with regard to achievement of quality of supplies, and parts, products or objects to be traded. There is a "product quality calculation program" that estimates the manufacturing quality of materials. The product quality calculation program is a program for calculating the product quality (defective rate) in consideration of the transaction target parts, the complexity of the structure of the product or material, the processing difficulty, and the like. However, since the present invention is incorporated into the factory quality calculation program for the product quality calculation program, the description thereof will be omitted.

First, an example of evaluation in the "factory quality calculation program" will be described with reference to the drawings.

In the system 11 of the procuring company according to the present invention, even if the supplier does not provide the defective performance data, the manufacturing factory level level (see FIG. 6) for each of the certifications and the performance check / judgment items corresponding to the above mentioned from the supplier. It is possible to estimate the susceptibility of the supplier to failure (failure occurrence rate: failure occurrence rate) by quantitatively evaluating using the evaluation method of the manufacturing factory only by obtaining the answer from the supplier). That is, the present invention has found that, in the system 11 of the procuring company, if quantitative evaluation is performed using the evaluation method of the manufacturing factory, it substantially agrees with the actual result data of the defect.

Therefore, the factors that cannot maintain the quality at the supplier are [defective occurrence suppressing power], [defective detecting power],
It is necessary to sub-classify the certification and performance check / judgment items (shown as middle items and small items in FIG. 6) so as to be able to correspond to [defect occurrence coping power].

By setting the subdivided evaluation items, [defective occurrence suppressing power], [defective occurrence coping power],
It becomes possible to correlate with [defect occurrence coping power], and in advance, for each of these items, defect creation which is a defect occurrence degree coefficient at a reference level (for example, a high level that does not cause the most defects) for a reference manufacturing operation. By preparing an evaluation calculation coefficient / constant database 40 that includes an inclusion coefficient, a defect extraction degree coefficient, a defect coping time coefficient, and a relative weight coefficient (a score for a response level from a supplier) for each item, a manufacturing factory It is possible to estimate the susceptibility to failure (degree of occurrence of failure), that is, the ability of the manufacturing factory. In addition, regarding the above-mentioned coefficients other than the above-mentioned relative weighting coefficient, in FIG.
The second most influential one is "○" = 2 points, the third most influential one is "△" = 1 point, and the most insignificant one is "x" = 0 point. Further, the relative weighting coefficient can be included in the failure occurrence degree coefficient.

The calculation coefficient / constant database 40
As a method of manufacturing, the standard manufacturing according to the level of each item that is actually measured by the supplier at the time of the first certification at the time of the previous certification or at the time of the previous certification or on a regular basis as actual performance data (result check results, factory level actual values, etc.). Defect creation factor, defect extraction factor, defect handling time, which is the defect occurrence factor at the reference level for each item, based on the defect creation level, defect extraction level, and defect handling time level, which are the defect occurrence levels for the work. The coefficient and the relative weight coefficient may be calculated. Naturally, the susceptibility to failure (defective occurrence rate) at the supplier, that is, the total defective occurrence rate in the manufacturing process, which indicates the ability, and the defective rate in the manufacturing process are also measured.

As described above, by preparing and preparing the calculation coefficient / constant database 40 based on the actual measurement value at the supplier, only the level for each item (reply from the supplier) is input at the time of re-certification. Thus, it is possible to evaluate and estimate the ability of the supplier (total defect occurrence rate in manufacturing process, defect rate in manufacturing process, and delivery defect rate). This is also because the inventors have confirmed that the actual measured value and the estimated value at the supplier are almost the same.

As described above, by simply inputting the level for each item in various suppliers, the ability (total defect occurrence rate in manufacturing process, defect rate in manufacturing process and delivery defect rate) of the supplier is evaluated and estimated. It becomes possible to judge whether or not re-certification is possible. Further, when re-certification is not possible, it is possible to present the improvement measure (medium item and / or small item increasing the defect rate in the manufacturing process) to the supplier.

Next, by inputting the level (response) for each item in various suppliers according to the present invention, the ability (supplement defect rate in manufacturing process total, defect rate in manufacturing process and delivery defect rate) of the supplier is obtained. , And an example of estimating the overall score and recertifying the factory will be further described.

FIG. 4 shows a system configuration for realizing factory recertification and collection of performance data according to the present invention. The certification system 11 provided in the buyer includes an input unit 112 including a keyboard, a mouse, a pen input tablet, a storage medium, a network, and an output device 115 including a display unit such as a display monitor and a printing unit. ,
The computer (computer) 113 that executes the factory recertification process and the process of collecting the actual data, the storage unit 111a that stores the certification standard information 41, the evaluation calculation program 42 that evaluates the certification, and the result and the certification standard are compared. A storage unit 111b that stores a determination program 43 that performs the certification pass / fail determination, a storage unit 111c that stores the evaluation calculation coefficient / constant data 40 used in the evaluation calculation, and a data (information) 44 that was certified at the time of the first certification. Storage unit 111
d, and actual data provided by the supplier at any time (results of actual results, factory-level actual values, etc.) 45
A storage device 111 having a storage unit 111e for storing
It is composed of a communication unit 116 that inputs and outputs information to and from another system through a network such as the Internet. The computer 113 includes a CPU 32, a ROM 31 that stores a predetermined program, a RAM 33 that temporarily stores various data, an input / output interface unit 34, a bus line 35, and the like.

Next, the recognition method according to the present invention will be described with reference to FIGS. 4 and 5. FIG. 5 shows a factory certification processing flow. First, the buyer's computer 113
Factory certification evaluation items (question items) as shown in FIG. 6, evaluation calculation coefficient / constant data 4 for the factory certification evaluation items
0 and the factory certification standard information 41 are created and stored in the storage units 111c and 111a, respectively.

Next, in step S51, in order to receive the first certification, the information certified at the time of the first certification or the previous certification (the data submitted by the supplier (the document with the answers from the supplier shown in FIG. Data and management data), which is sent from the supplier's system (computer) 12 to the buyer's computer 113 via the network, and the data 4 at the time of initial certification
4 is stored in the storage unit 111d. As the data 44 at the time of first certification, it is assumed that the actual data on manufacturing at the time of first certification is also stored. Of course,
The actual data on manufacturing at the time of initial certification is stored in the storage unit 1
It may be stored in 11e.

The supplier, in step S52,
Actual data on manufacturing history from time to time, based on requests from buyers or buyers (manufacturing process condition data consisting of results check results with manufacturing history, factory level actual values, etc .: proof that each question item is actually performed Data and management data) to be created, and step S5
In step 5, the created performance data relating to the manufacturing history is transmitted to the buyer's computer 113 and saved as the performance data 45 in the storage unit 111e at any time. As the actual result data 45 regarding the manufacturing history, it is assumed that the manufacturing history such as the product specification change from the buyer and the manufacturing process condition change on the supplier side is also stored. Basically, it is assumed that the storage unit 111e stores information regarding the manufacturing history including the actual result data after the first certification.

When the supplier wants to change the manufacturing process condition, first, in step S53, the buyer is notified of the request, and after approval, the actual data regarding the manufacturing history is accompanied. The created and changed data is transmitted to the buyer's computer 113 in step S55 and is sent to the buyer's computer 113, and is saved in the storage unit 111e as the actual data associated with the manufacturing process condition change.

In step S52, if the buyer wants to change the product specifications, he / she notifies the supplier,
In step S54, the supplier changes the manufacturing process condition in accordance with the change in the product specification, creates and modifies the actual result data regarding the manufacturing history associated with the modification in the manufacturing process condition, and in step S55, the supplier records the actual result regarding the created and modified manufacturing history. The data is transmitted to the buyer's computer 113 and stored in the storage unit 111e as actual data associated with the manufacturing process condition change in association with the product specification change.

Further, since the buyer can grasp the delivery failure rate, price, delivery date, etc., which are shown as quality indicators, the buyer can input them using the input unit 112 and store them in the storage unit 111e as actual data regarding the manufacturing history. Store.

Next, when it is necessary to correct the evaluation calculation coefficient / constant data 40 in accordance with changes in product specifications and manufacturing process conditions, the buyer computer 113 stores the storage section 111d in step S56. Based on the previously certified data 44 stored in the above and the actual data 45 regarding the manufacturing history stored in the storage unit 111e, the evaluation calculation coefficient / constant data 40 as described above is corrected and updated in the storage unit 111c. Store. That is, the computer 113 outputs the previously certified data 44 and the actual result data 45 regarding manufacturing shown in FIG. 6 to the display device 11 as an output device.
5, the evaluation calculation coefficient / constant data 40 may be corrected while viewing the displayed data. As the coefficient / constant data 40 for evaluation calculation, the points (including the relative weighting coefficient) with respect to the answers from the supplier for each question item, and “the defect prevention power”, “the defect detection power”, and “the defect detection power” for each question item The points to be assigned to each of the “defect occurrence countermeasures”, and the ratio of the in-manufacturing process defect rate (total) to the delivery defect rate will be corrected.

Next, when it is necessary to correct the certification standard 41 in accordance with changes in product specifications and manufacturing process conditions, the computer 113 shows in FIG. 6 obtained at the previous certification in step S57. Based on the submitted data 44, the revised evaluation calculation coefficient / constant data 40
The total quality evaluation and estimated total failure rate (total failure rate in manufacturing process and delivery failure rate), which is the total of the quality scores for "defect creation prevention power", "defect detection power", and "defect occurrence coping power". ) And the overall score, and based on the calculated overall quality evaluation at the time of initial certification, the estimated overall defective rate and the overall score, the certification standard information (data) 41 is corrected and updated in the storage unit 111a. And save.

Next, the certification update will be described.

First, in step S58, the buyer computer 113 notifies the supplier of the certification update. Next, in step S59, the supplier
Prepare the data to be submitted for certification renewal inspection (the documents shown in Fig. 6 in which the response from the supplier is filled out and the materials and management data to prove it), and in step S60, the supplier prepares the prepared certification renewal inspection. To the buyer's computer 113, and in step S61, the buyer's computer 113 accepts the supplier's sent submission data for acceptance of certification renewal.

Next, in step S61, the computer 113 refers to the record data relating to the manufacturing history that can be grasped by the buyer, which is stored in the storage section 111e,
By comparing the submission data stored in the storage unit 111d submitted by the supplier at the time of initial certification with the submission data submitted by the supplier at the time of this certification renewal, the question items with changes are extracted, and at least the major items are extracted. Conduct separate evaluations (“Quality”, “Technology”, “Price”, “Delivery time”). In particular, in terms of quality, the delivery defect rate that correlates with the overall in-manufacturing defect rate can be grasped by the buyer, so by estimating the in-manufacturing overall defect rate based on the submitted data submitted by the above supplier. , It becomes possible to evaluate the reliability of the submitted data (answers for each question item). Also, in the extracted question items with changes,
By referring to the attached performance data, it becomes possible to evaluate the reliability of the answer of the question item (certification evaluation item). In addition, it is possible to evaluate the reliability of the submitted data by comparing the evaluation value for each major item, for example, at the time of the previous accreditation, for the first time. Further, the reliability of the submitted data can be evaluated by referring to the delivery record data delivered to the buyer (for example, delivery failure rate). In this case, it may be necessary to estimate the total defective rate based on the submitted data.

In this way, if the submitted data shown in FIG. 6 at the time of this certification update is judged to be reliable, then the computer 113 uses the evaluation calculation program 42 to update this certification. Using the evaluation calculation coefficient / constant data 40 stored in the storage unit 111c on the basis of the submitted data shown in FIG. 6 at the time, “defective defect prevention power”, “defective detection power”, and “defect occurrence coping power”. The total quality evaluation and the estimated total defective rate (total defective rate in the manufacturing process and defective delivery rate), which is the total of the quality scores, and the total score are calculated.

Next, in step S62, the computer 113 causes the certification standard data 4 of the certified supplier.
1 is retrieved from the storage unit 111a and obtained. Then, in step S63, the computer 113 uses the determination program 43 to calculate the “changed question item”, “evaluation by major item”, “total quality evaluation and estimated total defective rate”, and "Comprehensive score"
And the certification standard data are compared to evaluate / determine whether or not the certification standard is satisfied.

Next, in step S64, the computer 113 creates a certification pass / fail notification and sends it to the material departments of the supplier and the buyer. In step S65, the supplier receives the certification result information. Next, in step S66, when the computer 113 determines that the certification has failed, the output device 115 outputs the information.
Is output by the buyer, and the buyer's material department performs order suspension processing for the supplier.

As described above, as a method of checking the reliability of the data submitted by the supplier to the buyer at the time of renewal of certification, the previous factory certification data, previous actual data or delivery actual data was used. ,
In this case, it is good for a supplier with a long transaction record, but in the case of a new customer, it may not work sufficiently because the actual record data is small. In any case, it is difficult to evaluate reliability based on past results for suppliers with few transactions.

Therefore, as a method of covering it,
The computer 113 traces and evaluates the factory level performance stored in the storage unit 111e after the certification, and the application at the time of certification is false to the supplier who operates (manufacturing control) at a quality level significantly lower than the certification level. Therefore, it is decided that the order is suspended or the transaction is suspended.

Specifically, the above-mentioned factory level actual value is a quality comprehensive evaluation index calculated based on the in-process defect rate value. That is, the above factory level actual value is a comprehensive quality evaluation index of the supplier factory calculated from the actual in-process defect rate value when the supplier factory actually manufactured.

Further, since the inventor has confirmed that there is a correlation between the total quality index and the in-process defect rate, if the actual value (actual value) of the in-process defect rate is known, the overall quality index is calculated backward. It becomes possible.

Next, this procedure and method will be described. (I) Calculation of factory-level actual value at the supplier: After receiving the certification renewal, the supplier always calculates the factory-level actual value after production, evaluates it voluntarily, and sends it to the buyer. Also submit. (Ii) Judgment on whether or not to continue ordering based on the factory level actual value: The buyer should confirm that the factory level actual value submitted by the supplier is (ii-1)
If it is within a certain range (within the factory standard actual value judgment standard), the actual result check is OK, and (ii-2) If it is not within that range, the actual result check is NG, and at least the order is suspended. In particular, if it is extremely low, the certification will be canceled.

If the supplier voluntarily checks the factory level actual value and finds that the standard is not satisfied, and immediately and voluntarily improves the process so as to satisfy the standard,
It may be OK to check the results.

Next, the storage of the certification information database 30 in the storage device 111 at the time of first certification, certification renewal, and performance check will be described with reference to FIG.

At the time of initial certification, the supplier system 1
In order to receive the certification inspection, the second section obtains the certification evaluation item and the certification standard from the buyer databases 111d and 111a via the Internet 15, and voluntarily evaluates the quality level of the supplier and obtains the factory evaluation result. Regarding this factory evaluation result, after obtaining internal examination and approval,
It is transmitted to the buyer's system 11 via the Internet 15, stored in the storage device 111 as the certification information database 30, and shared by the supplier and the buyer. At the time of initial certification, the supplier's voluntary evaluation results are confirmed in advance, and the supplier's factory is visited for on-site inspection. Then, based on the result of the on-site examination (actual data), the buyer's system 11 receives the response to the certified evaluation item from the supplier, and based on the evaluation calculation coefficient / constant data 40 stored in the storage unit 111c. The factory evaluation calculation is executed by using the evaluation calculation program 42 to obtain the qualification evaluation result, and the judgment program 43 is used to compare the qualification evaluation result with the qualification standard to make a pass / fail judgment. The computer 113 that is the buyer system 11
Shows the first supplier (factory) certification result in the storage unit 11
It is stored in the database 1d as the database 44 at the time of the previous certification.

Then, in order to receive the certification renewal, the supplier evaluates the factory based on the certification evaluation items in the system 12 and submits the factory evaluation result to the buyer's system 11 via the Internet 15 to obtain the factory certification information. DB
It will be stored in 30. Buyer system 11
Acquire the information necessary for the certification from the factory certification information DB30, execute the factory certification (factory evaluation calculation and pass / fail judgment), obtain the updated certification result, store it in the factory certification information DB30, and confirm that the buyer has passed the certification. In that case, notify the supplier of the order.

The supplier carries out the production and inspection of the product based on the order notification.

Further, in order to reduce the fluctuation of the factory level from the time of certification as much as possible, in particular, in order to prevent the deterioration of quality, the buyer periodically submits a request for a performance check to the supplier. Then, the supplier's system 12 calculates the factory level actual value which is the factory level actual result data, and submits the calculated factory level actual result data to the buyer's system 11 via the Internet 15. The information required for the same check as at the time of certification is acquired from the information DB 30, the same result check as at the time of certification is executed, the check result is acquired and stored in the factory certification information DB 30, and the buyer confirms that the check result is OK. In that case, notify the supplier of the order.

The supplier carries out the production and inspection of the product based on this order notification.

Further, when the factory is to be improved if necessary, the result check is voluntarily performed, and the result check result and the improvement contents as the manufacturing history are submitted to the buyer's system 11 via the Internet 15 and the factory is submitted. It will be stored in the certification information DB 30.

According to the factory certification method of the present invention described above, the certification of the factory can be efficiently updated for the procurement maker, and high quality parts can be continuously procured. In addition, for the supplier, the man-hours and time required to prepare documents for certification renewal and respond to on-site inspections are greatly reduced, and the time and cost to work on the quality improvement of parts can be secured accordingly, and high quality is promoted. Is effective.

[0103]

According to the present invention, it is possible to significantly reduce the time and cost of operations related to factory certification for products, and it becomes possible to continuously procure and deliver high quality products. , The effect of promoting high quality as an entire industry.
