Description

  The present invention generally relates to a design support apparatus, a design support system, a design support method, a design support program, and a computer readable recording medium used for support of a designer in a product design process, and in particular, user convenience. The present invention relates to a design support apparatus, a design support system, a design support method, a design support program, and a computer-readable recording medium.

  Conventionally, in the field of product design, rather than a scene where all or part of a product is newly developed from the beginning, by utilizing design assets developed in the past and adding some changes to meet the product specifications there So-called diversion designs are being made to meet new specifications. In the diversion design, it can be said that a defect occurring in the product design / manufacturing process has a relatively high probability of occurring in a portion (design change point) where an existing (diversion source) design asset is changed. For this reason, in recent years, paying attention to design change points, considering and predicting possible problems and their causes in advance, and taking countermeasures based on the results, improve the degree of complete design at an early stage. Techniques aimed at this have been adopted.

  Recently, a system has been proposed that aims to store such design defect information electronically using a database, and output defect information that matches the search condition as a search result according to the input of the search condition. It is coming.

  On the other hand, the database that constitutes the design defect information search system has a master (for example, system level master, module level master, element level master, etc.) having a hierarchical structure for each design change point examination item. Techniques aimed at preventing leakage and oversight have been proposed (see, for example, Patent Document 1).

  In addition, design changes that do not depend on a specific product using design quality management information that has been registered as linking information in which predicted defects, effects that cause defects, and countermeasures for defects have correlations, based on design change points There has also been proposed a technique aimed at implementing a countermeasure against defects by using a point database and using this (see, for example, Patent Document 2).

JP 2005-346383 A JP-A-2005-149142

  However, in the above prior art, failure modes when a part of the structure of a product is changed are searched, or knowledge about design change points is widely used without being limited to a specific product. Although it is possible to search for these pieces of information, it is not possible to grasp simply and in detail what kind of design should be actually made using this information.

  In addition, as described in Patent Document 2, when the knowledge about the design change point is to be widely used in various products without being limited to a specific product, an actual measurement value obtained when a problem occurs is directly changed to another product. It is assumed that there will be a situation where the product cannot be used. Specifically, even if the actual measurement value or actual measurement result obtained in the event of a malfunction is a numerical value related to the length of a certain part or the material name of a certain part, the information is used for the corresponding part of another product. It is difficult to use it as it is, and to use it for another product, the numerical value related to length is expressed as a ratio based on a certain part, or the material is quantified based on properties (such as hardness), etc. It is considered necessary to generalize the actual measurement values. In addition, when applying this generalized numerical value to a product that is currently being designed, it is necessary to convert and convert it to specific numerical values and materials to correspond to the dimensions and materials of the product. Therefore, it may take time and effort to design.

  Accordingly, the present invention has been made in view of the above problems, and provides a design support apparatus, a design support system, a design support method, a design support program, and a computer-readable recording medium that improve user convenience. The main purpose is to do.

  A first aspect of the present invention for solving the above-described problem is a memory in which past information is stored in association with a combination of a pre-change state and a post-change state for each design change point generated in the product design process. Past information corresponding to the combination of the state before the change and the state after the change when the specific part is changed in response to the designation of the specific part of the product by the means and the designer from the storage means And a past information providing unit provided to a designer.

  According to the first aspect, the past information providing unit corresponds to the combination of the state before the change and the state after the change when the specific part is changed in response to the specification of the specific part of the product by the designer. Since the past information is provided to the designer, the designer can appropriately determine the changed state of the specific portion by referring to the past information. As described above, since it is possible to assist the designer in determining the state after the change of the specific part, it is possible to improve the convenience of the designer (user).

  In the first aspect, the past information may include score information of actual values related to the combination of the state before the change and the state after the change. In such a case, it is possible to improve the convenience of the designer (user) by providing the past performance value in order to determine the change content of the specific part. In this case, the score information may include the reliability of the actual value. In such a case, the convenience of the designer (user) can be further improved. Here, the “score information” is information indicating various indexes indicating the results of the combination of the state before the change and the state after the change. As an example, the “score information” indicates the state before and after the change. ”,“ Actual number of cases ”indicating how many of those changes have occurred in the past,“ Reliability ”described later,“ Total number of defects ”indicating the number of defects that occurred in the change, and the number of defects for which permanent countermeasures have already been implemented. Various information such as “Number of defects with permanent countermeasures” displayed, “Number of defects with permanent countermeasures” indicating the number of defects for which permanent countermeasures have not yet been executed, and “Latest defect occurrence date” indicating the most recent day when the defect occurred Is included. The “reliability” of the actual value is an index indicating how much the past actual value can be trusted. For example, the degree of reliability can be defined using the elapsed time from the drawing work as an index from the viewpoint that the aging of the product is progressed as the elapsed time from the drawing work is increased. In addition, since it is considered that a defect or the like is being examined as the manufacturing process progresses, it is possible to define the reliability using the progress of the manufacturing process as an index. Further, from the viewpoint that the aging of the product progresses as the number of products produced increases, the reliability can be defined using the number of products produced as an index. In addition, the reliability of products varies depending on the people and factories involved in product development, etc., so the degree of development reliability in development factories and development teams (number, system, development ability such as past development results, It is also possible to define the degree of reliability using as an index the ones classified by the corresponding area etc. (also called rank). Further, the present invention is not limited to the above, and it is also possible to define the reliability using various indexes according to the maturity of the product and the people and devices related to the product.

  In the first aspect, the past information may include case information related to a combination of the state before the change and the state after the change. In such a case, the convenience of the designer (user) can be improved by providing case information (case contents) related to the combination of the state before the change and the state after the change. Further, from the viewpoint of the convenience of the designer (user), the past information may include a plurality of types of case information for each degree of association with the combination of the state before the change and the state after the change. Further, the plurality of types of case information include first case information that matches all of the state before the change, the state after the change, and the type of change, the type of change, and the state before the change. Second case information that matches any of the state and the state after the change, and third case information that matches any one of the state before the change, the state after the change, and the type of change It is good also as including at least one of these. In this way, by distinguishing a plurality of past information according to importance or the like, it is possible to support the efficiency of browsing past information by a designer.

  In addition, as described above, when a plurality of types of case information is included in the past information, the past information providing means does not allow the designer to browse specific case information among the plurality of types of case information. In the event of a failure, a warning may be issued to the designer. For example, by notifying the designer when past information with relatively high importance has not been viewed, it is possible to suppress omission of confirmation by the designer of past information that is required at the minimum in the design. is there.

  In the first aspect, the revision information of the standard information is output based on the standard information holding means for holding the standard information regarding the change for each part of the product and the past information stored in the storage means. Revision information output means. The revision information output means outputs the revision information of the standard information based on the stored past information, so that the convenience of the revision work of the standard information by the user is improved. Here, the past information may include failure information in which a failure has occurred at the design change point and success information in which a failure has not occurred at the design change point. Based on the success information and failure information, revision information of the standard information may be output. Of these, “failure information” includes not only the number and frequency of failures, the location and content of failures, but also information such as the results of countermeasures taken (number of steps and impact). It is a concept. Further, the revision information output means includes the quantity information of failure information when the changed state is within the range of the standard information in the past information, and the changed state of the past information is the standard information. It is good also as outputting at least one of the quantity information of success information in the case of being out of the range of information as said revision information. By outputting such quantity information, the convenience of the standard information revision work by the user is improved. In addition, the revision information output means includes the quantity of failure information when the state after the change in the past information is within the range of the standard information, and the state after the change among the past information is the standard information. It may be determined whether to revise the standard information on the basis of at least one of the number of success information in the case of being out of the range.

  The second aspect of the present invention relates to information processing means used by a designer who designs a product and a combination of a state before change and a state after change for each design change point generated in the product design process. Corresponding to the combination of the state before the change and the state after the change when the specific part is changed in response to the designation of the specific part of the product in the information processing means And a past information providing unit that transmits the past information from the storage unit to the information processing unit.

  According to the second aspect, the past information providing means corresponds to the combination of the state before the change and the state after the change when the specific part is changed in response to the specification of the specific part of the product by the designer. Since the past information is provided to the information processing means, the designer who uses the information processing means can appropriately determine the changed state of the specific part by referring to the past information. As described above, since it is possible to assist the designer in determining the state after the change of the specific part, it is possible to improve the convenience of the designer (user).

  In the second aspect, the past information may include score information of actual values related to a combination of the state before the change and the state after the change, and the score information includes the actual value Can be included.

  In the second aspect, the past information may include case information related to a combination of the state before the change and the state after the change, and further, the state before the change and the change A plurality of types of case information can be included for each degree of association with a combination with a later state.

  In the second aspect, the standard information revision means for holding the standard information regarding the change for each part of the product, and the revision information of the standard information based on the past information stored in the storage means. Revision information output means for outputting. The revision information output means outputs the revision information of the standard information based on the stored past information, so that the convenience of the revision work of the standard information by the user is improved. Further, the past information includes failure information in which a failure has occurred at the design change point and success information in which a failure has not occurred at the design change point, and the revision information output means includes the success information The revision information of the standard information may be output based on the information and the failure information. In addition, the revision information output means includes the quantity information of failure information when the changed state of the past information is within the range of the standard information, and the changed state of the past information is the standard information. It is good also as outputting at least one of the quantity information of success information in the case of being out of the range of information as said revision information. By outputting such quantity information, the convenience of the standard information revision work by the user is improved.

  A third aspect of the present invention relates to a step of receiving a designation of a specific part of a product by a designer and a combination of a state before change and a state after change for each design change point generated in the design process of the product. And providing past information to the designer according to the designation by the designer from the past information stored in this way.

  According to the third aspect, in the providing step, the specification of the specific part of the product by the designer is accepted, and the combination of the state before the change and the state after the change when the specific part is changed is supported. Since the past information is provided to the designer, the designer who uses the information processing means can appropriately determine the changed state of the specific portion by referring to the past information. As described above, since it is possible to assist the designer in determining the state after the change of the specific part, it is possible to improve the convenience of the designer (user).

  According to the fourth aspect described above, design information on past information corresponding to the combination of the state before the change and the state after the change when the specific part is changed in response to the specification of the specific part of the product by the designer. Therefore, the designer can appropriately determine the changed state of the specific part by referring to the past information. As described above, since it is possible to assist the designer in determining the state after the change of the specific part, it is possible to improve the convenience of the designer (user).

  A fifth aspect of the present invention is a computer-readable recording medium on which the design support program of the present invention is recorded.

  The design support apparatus and method, the design support system, the program, and the recording medium of the present invention have an effect of improving user convenience.

  Hereinafter, an embodiment of a design support system of the present invention will be described in detail with reference to FIGS.

  FIG. 1 is a diagram showing a schematic configuration of a design support system 100 according to the present embodiment. The design support system 100 is a system for supporting a designer in designing various elements such as dimensions, shapes, materials, and colors of a certain part of a certain device. As shown in FIG. 1, the design support system 100 includes a plurality of designer terminals 10, an administrator terminal 12, a registrant terminal 14, a database server 16, and an application server 18. These terminals 10, 12, 14 and servers 16, 18 are connected by a network 20 such as a LAN, a WAN, or the Internet.

  The designer terminal 10 is composed of a PC (Personal Computer). The designer terminal 10 may be a mobile phone, a PDA (Personal Digital Assistants), or the like. In FIG. 1, a plurality of designer terminals 10 (three as an example here) are prepared, but one designer terminal 10 may be provided.

  Similarly to the designer terminal 10, the administrator terminal 12 and the registrant terminal 14 are also configured from a PC or the like.

  The database server 16 stores various data necessary for design support. As shown in FIG. 2, the examination item database (DB) 22, the check item DB 24, the function / structure (parts) DB 26, the standard DB 28, the change It has point achievement DB30, past information DB32, etc.

  The examination item DB 22 stores a list 50 of examination items as shown in FIG. The check item DB 24 stores a check item table 52 as shown in FIG. The function / structure (component) DB 26 stores information about the structure and components, images, and the like. The standard DB 28 stores standards (reference range information) related to structures and parts. This standard includes items (for example, spring constants) that can be set by the material, mass, and parameters as well as the dimensions of the structure and parts. Further, the change point result DB 30 stores score data 56 shown as an example in FIG. 9. Further, the past information DB 32 stores defect information 58 (including required confirmation information, recommended recommendation information, and reference information) shown in FIG.

  Returning to FIG. 2, the application server 18 includes a so-called computer, that is, a CPU, SRAM, RAM such as DRAM, ROM such as flash memory, and the like, and includes a plurality of modules (the information registration module 40, shown in FIG. 2). A registration result distribution module 42, a past information management module 44, a score data management module 46, and a check item update module 48).

  Among these, the information registration module 40 is a module for executing processing such as registration of defect cases described later, and the registration result distribution module 42 is based on the data input by the designer to the designer terminal 10 according to the data entered by the designer. This is a module that supports the designer's design by appropriately providing data stored in the inside. The past information management module 44 is a module for managing past information (including defect information) stored in the past information DB 32, and the score data management module 46 is score data stored in the change point result DB 30. The check item update module 48 is a module that appropriately updates the check item table 52 stored in the check item DB 24.

  Next, a design support method performed in the design support system 100 of the present embodiment will be described along the flowcharts of FIGS. 3 and 4 with reference to other drawings as appropriate. In the following description, as an example, it is assumed that the diversion source model is α-1 and the related model is α-2, as shown in FIG.

  The process of the flowchart of FIG. 3 is started when the designer starts up design support software (computer program) on the designer terminal 10. First, in step S10 of FIG. 3, the registration result distribution module 42 of the application server 18 extracts a list of examination items from the examination item DB 22, transmits the list to the designer terminal 10, and displays it on the screen of the designer terminal 10. To do. An example of the display state on the designer terminal 10 in this case is shown in FIG. As shown in FIG. 6, the examination item list 50 includes items such as “examination of part β” and “examination of part γ”. Note that the part β is, for example, a part having a shape as shown in FIG.

  Next, the registration result distribution module 42 waits until the designer selects a review item in step S12 of FIG. In this case, after the display of FIG. 6 is made, the designer can select one item from the list 50 of the examination items using the mouse or the keyboard. In the registration result distribution module 42, the process proceeds to step S14 when the designer makes a selection. Here, it is assumed that the designer has selected “Examination of site β” from the examination item list 50.

  In next step S <b> 14, the registration result distribution module 42 extracts a check item table corresponding to the selected examination item from the check item DB, transmits it to the designer terminal 10, and displays it on the designer terminal 10. An example of the display state on the designer terminal 10 in this case is shown in FIG. As shown in FIG. 7, the check item table 52 includes items of “check contents”, “standard”, “diversion source record”, and “examination value”.

  Among these, “Check Contents” indicates which dimension to consider among the dimensions A, B, and C of the part β, and “Standard” indicates each part such as dimensions and materials of each part. The standard range for setting is displayed. In “Diverted Source Actual”, the actual value such as the size and material of the model that is the source of the diversion design, and the actual status indicating whether the actual value was a success example (OK) or a failure example (NG). Is displayed. Note that the column “examined value” is blank so that the designer can input an arbitrary value.

  Further, under the check item table 52 on the screen of the designer terminal 10, the development stage of the diversion source model is displayed. Here, the development stage will be described.

  As shown in FIG. 8, stages 1 to 4 are set as examples of the development stage, and the larger the numerical value of the stage, the higher the reliability (reliability). In this case, the designer or the like can classify the stage using various elements as indices. For example, as shown in FIG. 8, the elapsed time from the drawing work can be used as an index of reliability. In this case, as the time elapsed since the drawing work is performed, the quantity of the product to be manufactured increases, so that the number of examinations for the product increases and the maturity of the product increases. Therefore, as shown in FIG. 8 as an example, the lowest reliability (stage 1) is handled from the prior examination until the drawing work is performed, and the highest reliability is obtained when 12 months or more have passed since the drawing ( It can be handled as stage 4). Further, the present invention is not limited to this, and the progress of the process can also be used as an index of reliability as shown in FIG. In this case, it means that the product is closer to completion as the process progresses, and the closer the product is to completion, the more the examination of product defects and the like is considered that the product is matured. Therefore, as shown in FIG. 8 as an example, the stage in the product design process is set to the lowest reliability (stage 1), and the reliability is increased as the production technology / mold design process, mold manufacturing process, and molding process progress. High (Stage 2, 3, 4) can be handled. Further, as an index of reliability, as shown in FIG. 8, the cumulative production number can be used. This is because, as the cumulative production number increases, more studies on product defects and the like are conducted, and the reliability is considered to be higher. In this case, as shown in FIG. 8 as an example, the pre-production (cumulative production number 0) is the lowest reliability (stage 1), and the cumulative production number is 1 to 1000, 10001 to 20000, 20000 or more. As it becomes, it can be handled with high reliability (stages 2, 3, and 4). Furthermore, classify development factories and development teams according to the degree of development reliability (number, structure, development ability such as past development results, applicable regions, etc., hereinafter referred to as “rank”). It is also possible to set the stage according to the rank (A or higher to D). Note that it is possible for a user such as a designer to freely determine which criterion is used to set the stage. Moreover, it is good also as judging a stage using a some parameter | index. In this case, if it is determined that the index is in a different stage, for example, the lowest stage among the stages can be used as the development stage. For example, the average value of each stage can be used as the development stage. In the example of FIG. 7, it is displayed that the rank of the model that is the diversion source belongs to the rank “stage 4”.

  Next, in step S16, the registration result distribution module 42 determines whether or not a check item has been selected by the designer. In this case, for example, as shown in FIG. 7, for example, the designer places the mouse pointer on the “check contents” field (here, “set dimension A”) that the designer wants to consider (see mouse pointer 101). ) Click to make a selection.

  If the determination in step S16 is negative, the process proceeds to step S20, and the registration result distribution module 42 determines whether or not the designer has input a numerical value to the examination value in the check item. If the determination here is negative, the process returns to step S16. Thereafter, when it is determined that a check item has been selected, the determination in step S16 is affirmed and the process proceeds to step S22. On the other hand, if it is determined in step S20 that the examination value has been input, the process proceeds to step S48 in FIG.

  In step S <b> 22, the registration result distribution module 42 extracts score data for the selected check item from the change point result DB 30 and displays it on the designer terminal 10. In this case, score data 56 as shown in FIG. 9 is displayed on the right side of the check item. In this embodiment, as an example, the score data includes “change contents”, “number of actual results”, “reliability”, “total number of defects”, “number of defects with permanent countermeasures”, “number of permanent defects with no permanent countermeasures”. , “Latest defect date” is included. However, the items of the score data are not limited to these, and a user such as a designer can freely set and change the items.

  Of these, “Change” describes the state before the change (change) and the state after the change (change), and “Number of results” shows the change (change) that matches the change in the past. Describes how much was done.

  In the “reliability”, any one of A, B, C, D, and diagonal lines is displayed as an example of an index of the reliability of the change content. Here, “reliability” will be described with reference to FIG. This reliability is determined in consideration of the relationship with the stages 1 to 4, and is determined based on the determination condition of FIG. As shown in FIG. 10, when there is no past defect in stage 1, “reliability D” is obtained, and when there is no past defect in stage 2, “reliability C” is obtained. If there is no failure, it becomes “Reliability B”, and if there is no defect in the past in stage 1, it becomes “Reliability A”. If there is any defect (NG) in the past regardless of the development stage Since it falls out of the reliability target, the reliability column is hatched. In addition, when the number of achievements increases, a plurality of reliability levels of reliability A, B, C, and D may be satisfied. In such a case, the lowest reliability is set in the reliability column of FIG. Will be displayed. However, the present invention is not limited to this. For example, an average of a plurality of reliability levels may be displayed in the reliability level column. Specifically, when there is no defect in stage 1 and stage 3, the reliability C can be displayed in the reliability column. Further, for example, a plurality of reliability levels may be weighted according to the number of actual results, and the weighted average may be displayed in the reliability column. Specifically, if there are 2 successful cases in stage 1 and 4 successful cases in stage 4, the weighted average is (1 × 2 + 4 × 4) / 6 = 3, so it corresponds to stage 3 The reliability B to be displayed can be displayed in the reliability column.

  Returning to FIG. 9, the “total number of defects” describes how many defects have occurred in the past when the change was made. Describes the number of cases where the countermeasures for the permanent measures have been completed and the number of cases where the countermeasures for the permanent measures have not been completed in the event of a failure.

  In addition, “date of latest defect occurrence” describes the most recent date of the defect. The “number of actual results” means the sum of the total number of defects (number of failures (NG number)) and the total number of successful cases (OK number). That is, in the present embodiment, both the number of NGs and the number of OKs are acquired from the past cases, and the total is displayed. Further, the score data 56 in FIG. 9 may be rearranged in the display order so that the clicked items are in ascending order or descending order by clicking an item name such as “the number of achievements” or “the total number of defects”. It can be done. Thereby, the designer can examine score data from various viewpoints.

  In the above description, the score data 56 prepared in advance is stored in the change point result DB 30, and the registration result distribution module 42 stores the score data for the check item selected by the designer. Although the case where it extracted from and displayed on the designer terminal 10 was demonstrated, it is not restricted to this. For example, various data groups that can constitute the score data 56 are stored in the change point result DB 30, and when the check item is selected by the designer, the data group is selected according to the check item. The score data may be created (data calculation / calculation / extraction / organization etc.) and displayed each time in the form of the digest version.

  Next, in step S24 of FIG. 3, the registration result distribution module 42 determines whether or not the contents of change of score data by the designer have been selected. The selection in this case is performed when the designer clicks on the contents to be examined out of the “change contents” items (see the mouse pointer 102 in FIG. 9).

  If the determination in step S24 is negative, the process proceeds to step S26, and the registration result distribution module 42 determines whether or not the designer has selected the actual number of cases. In this case, the number of results is selected when the designer clicks a portion indicated by a broken line in FIG. 9 (see the mouse pointer 103). If the determination in step S26 is affirmative, the process proceeds to step S28, and the registration result distribution module 42 displays a graph regarding the number of results. The graph related to the actual number of cases in this case is as shown in FIG. 11, and the upper graph shows the number of successful cases (OK number) when the dimension A is changed from 0.5 mm to 1.5 mm in each development stage. ) And the number of failure cases (number of NG). The middle graph shows the number of successful cases (OK number) and the number of failed cases (NG number) when the dimension A is changed from 0.5 mm to 1.0 mm in each development stage. Further, the lower graph shows the number of successful cases (OK number) and the number of failed cases (NG number) when the dimension A is changed from 0.5 mm to 0.4 mm in each development stage.

  In the upper graph of FIG. 11 (0.5 mm → 1.5 mm), since there was a defect (NG) in the past regardless of the development stage, the reliability is hatched (see FIG. 9). Further, in the middle graph (0.5 mm → 1.0 mm) in FIG. 11, since no defect has occurred in the past in stages 1 to 4, all the conditions of reliability A to reliability D are satisfied. The reliability in such a case is the lowest reliability D among them (see FIG. 9). Further, in the lower graph of FIG. 11 (0.5 mm → 0.4 mm), since no malfunction has occurred in the stage 3 in the past, the reliability is B (see FIG. 9).

  In the next step S30, the registration result distribution module 42 determines whether or not “switching” has been selected by the designer. The selection in this case is performed when the designer clicks a “switch to list display” button displayed in the upper right of FIG. When the determination in step S30 is affirmed, the process proceeds to step S32, and the registration result distribution module 42 performs display switching. In this case, the list display regarding the results shown in FIG. 12 is performed from the graph display of FIG. This list includes items of “change contents”, “model name”, “development stage”, “result status”, “defect occurrence date / time”, and “permanent countermeasure”. In addition, by performing the graph display of FIG. 11, there is an advantage that the designer who sees the graph display can compare and consider the number of results for each stage of each combination. Further, by performing the list display of FIG. 12, there is a merit that the designer can compare and consider the model name and failure occurrence date and time of each combination.

  Next, in step S34, it is determined whether or not “close” is selected. The selection in this case is performed by the designer clicking the “Close” button displayed in the upper right of FIG. If the “close” button has not been selected, the process returns to step S30 to determine whether or not switching display has been selected. If there has been a selection, switching from the graph display to the list display is performed in step S32. Then, the process proceeds to step S34 again. Thereafter, when the “close” button in FIG. 11 or the “close” button in FIG. 12 is clicked and the determination in step S34 is affirmed, the process proceeds to step S36.

  In step S36, the registration result distribution module 42 determines whether or not the designer inputs a numerical value for the examination value in the check item. If the determination here is negative, the process returns to step S24. Thereafter, when it is determined that the change content has been selected on the score data 56 of FIG. 9, the determination in step S24 is affirmed and the process proceeds to step S38. On the other hand, if it is determined in step S36 that an examination value has been input, the determination is affirmed and the process proceeds to step S48 in FIG. Here, as an example, as shown by the mouse pointer 102 in FIG. 9, “0.5 → 1.5” is selected from the “change contents” item, and the determination in step S24 is affirmed. Thereafter, the process proceeds to step S38.

  Next, in step S38 of FIG. 3, the registration result distribution module 42 extracts defect information from the past information DB 32, transmits it to the designer terminal 10, and displays, for example, the degree of association on the screen of the designer terminal 10. Display in descending order.

  Specifically, as shown in an example in FIG. 13, the defect information is classified into “confirmation required” information, “confirmation confirmation” information, and “reference” information in descending order of relevance. Among these, for example, “confirmation required” information includes the change contents selected by the designer, the state before the change (here, 0.5 mm), the state after the change (here, 1.5 mm), the change action (here) Then, the case information matches all of the dimension changes. In addition, the “recommended confirmation” information is relatively less relevant than the “required confirmation” information, and the change content selected by the designer, the case information in which the state before the change and the change action match, or This is case information in which the change content selected by the designer matches the state after the change and the changing action. Furthermore, the “reference” information is relatively less relevant than the “recommendation recommended” information, and any one of the change content selected by the designer, the state before the change, the state after the change, and the change action is selected. Is the case information that matches.

  After the defect information as described above is displayed, in step S40 of FIG. 4, the registration result distribution module 42 determines whether or not the designer has selected the defect information. Here, as shown in FIG. 13, the defect information can be selected by clicking the defect information (for example, confirmation-required information).

  If the determination in step S40 is negative, the process proceeds to step S42, where the registration result distribution module 42 determines whether or not the designer has entered a numerical value for the examination value in the check item. If the determination is negative, the process returns to step S40. Thereafter, if it is determined that defect information has been selected, the determination in step S40 is affirmed and the process proceeds to step S44. If it is determined that the examination value has been input, the determination in step S42 is affirmed. Then, the process proceeds to step S48.

  In step S44, the registration result distribution module 42 extracts the details of the defect information from the past information DB 32 and displays it on the screen of the designer terminal 10. In this case, the details 60 of the defect information as shown in FIG. 14A is popped up. In the details 60 of the defect information, the specific contents of the defect and the contents of the countermeasure (correction contents) are described in detail.

  After confirming the defect information details 60 in FIG. 14A, the designer clicks a button to close the window to hide the defect information details 60 as shown in FIG. 14B. can do.

  Next, the registration result distribution module 42 stands by until a numerical value is input by the designer in the examination value column in the check item table 52 in step S46 of FIG. Then, if the determination in step S46 is affirmed, or if the determination is affirmative in any of steps S20 and S36 in FIG. 3 and step S42 in FIG. 4, the process proceeds to step S48.

  In the present embodiment, it is assumed that, as a result of the designer confirming the details of the defect information details 60 in FIG. 14A, the dimension A is preferably set to 1.0 mm. As a result of the examination, it is assumed that the designer has entered “1.0” in the examination value column of the check content “Set dimension A” as shown in FIG. Here, in the examination value column, numerical values other than the numerical values “0.5”, “1.0”, and “0.4” displayed in the graph of FIG. Of course, it is also possible to input. That is, in the present embodiment, not only the case where a numerical value considered appropriate from the numerical values displayed in FIG. 11 and FIG. 15 is selected and entered in the examination value column, but also displayed on the designer terminal 10. As a result of examining various past performance information, it is possible to enter a numerical value other than the above three numerical values in the column for the examination value after considering what kind of trouble occurs in which case. .

  The information registration module 40 stores the examination value in the change point record DB 30 assuming that the status of the change content is OK when the examination value is input in step S46.

  Next, in step S48, the registration result distribution module 42 refers to the past information DB 32 to determine whether there is defect information related to the examination value input in step S35, that is, the change content “0.5 mm → 1. It is determined whether or not there is defect information related to “0 mm”.

  Here, according to the score data shown as an example in FIG. 15, there is no defect information regarding “0.5 mm → 1.0 mm” (the item of the total number of defects is “0”). The determination here is denied, and the processing of FIG. 3 is terminated. That is, the examination value of the dimension A is determined as “1.0 mm”, and the entire process is finished.

  On the other hand, if there is defect information related to the examination value in step S48 (for example, “1.5 mm” is input as the examination value), the determination in step S48 is affirmed and the process proceeds to step S50. To do. Then, in the next step S50, the registration result distribution module 42 determines whether or not the confirmation essential information for the examination value has been displayed, that is, whether or not the confirmation essential information has been displayed through step S44. If the determination here is affirmative, the processing of FIG. 4 is terminated. If the determination is negative, in step S52, the registration result distribution module 42 requires confirmation as shown in FIG. Forcibly display information (details of defect information). In this case, a “confirmation button” and a “reconsideration button” are displayed together with details of the defect information. The reason why the “reexamination button” is displayed together with the “confirmation button” is to provide an opportunity to change the examination value to the designer who has seen the compulsory displayed confirmation essential information.

  Next, the registration result distribution module 42 stands by until either the “confirmation button” or the “reconsideration button” is selected by the designer in step S54. When any button is selected, the process proceeds to step S56, and the registration result distribution module 42 determines whether or not the selected button is a “confirmation button”. If the determination here is affirmed, all the processes in FIG. 3 and FIG. 4 are terminated. If the determination here is negative, the processing is repeated from step S46.

  As described above, by executing the processes of FIGS. 3 and 4, the designer can determine the examination value while referring to the past defect information. It is possible to prevent the setting of a study value considered to be high in advance.

  Next, with respect to the processing for pre-registering the past information (defect information and score data) used in the processing of FIGS. 3 and 4 in the past information DB 32 and the change point result DB 30, FIGS. This will be described with reference to the flowchart. Note that this registration process is performed using the designer terminal 10, the administrator terminal 12, and the registrant terminal 14. In other words, the registration process includes the designer, the administrator, and the registrant. Will be involved.

  When a designer finds a problem while designing, when the designer activates the designer terminal 10 and starts up the problem registration software (computer program), in step S60, the application server 18 The information registration module 40 extracts the occurrence location list and the defect list from the function / structure (part) DB 26 and displays them on the designer terminal 10. Here, the occurrence location list includes part names such as “part β” and “part γ”, and the defect list includes defect names such as “sink” and “crack”.

  Next, in step S62, the information registration module 40 stands by until selection by the designer using the list displayed in step S60 is performed.

  Then, when the selection by the designer is made, the process proceeds to step S64, and the information registration module 40 displays related defect information from the past information DB 32. The related defect information in this case has substantially the same content as the defect information details 60 in FIG. 14A, and includes details of the event of the defect and a countermeasure example for the defect.

  Based on the related defect information, the designer examines provisional countermeasures for the currently occurring defects and actually executes the provisional countermeasures. Then, when the result of the provisional countermeasure becomes clear, the designer registers the result from the designer terminal 10.

  In the next step S66, the information registration module 40 determines whether or not a countermeasure result has been registered. If the determination is affirmed, the process proceeds to step S74. If the determination is denied, the process proceeds to step S68 to determine whether the delivery date has passed. If the delivery date has not passed at this stage, the process returns to step S66, and steps S68 and S70 are repeated until the delivery date has passed while no countermeasure result is registered.

  If the delivery date has passed without registration of the countermeasure result, the determination in step S68 is affirmed, so the information registration module 40 issues a warning to the designer terminal 10 in the next step S70. As a warning method in this case, direct warning display on the screen may be adopted, warning information is distributed via e-mail, warning sound is output via a speaker, or a combination thereof. It may be adopted.

  After performing the warning as described above, the information registration module 40 waits until the countermeasure result is registered by the designer in step S72, and proceeds to step S74 when the registration is performed. .

  Thereafter, in steps S74 and S76, the information registration module 40 distributes the registered contents to the terminals of related parties of the related model (specifically, those who are involved in designing the same part of the same device (different model)). Or distributed to related parties of the same model (specifically, those who are involved in the design of another part of the same device (same model)). This distribution has the significance of notifying the above parties of the digest version of the registered contents in a timely manner and disseminating the defect information.

  Then, when the process of step S76 is completed, the process shifts from the process on the designer terminal 10 to the process on the administrator terminal 12 (flowchart in FIG. 18).

  In step S82 of FIG. 18, the information registration module 40 instructs the administrator to evaluate the provisional countermeasure result from the administrator terminal 12. Next, in step S84, the information registration module 40 stands by until the provisional countermeasure result is evaluated by the administrator and the evaluation result is input from the administrator terminal 12. Then, when the evaluation result is input on the administrator terminal 12, the process proceeds to step S86.

  Next, in step S86, the provisional countermeasure result is transmitted to the registrant terminal 14, and the process proceeds to processing on the registrant terminal 14.

  In the next step S110, the information registration module 40 stands by until a registration procedure from the registrant terminal 14 by the registrant is performed. In this case, the registrant confirms the evaluation result transmitted from the manager terminal 12 in step S86 described above, and then performs a registration procedure.

  Then, when the registration procedure by the registrant is performed, the process proceeds to step S112, and the information registration module 40 performs a process of registering the evaluation result. After that, in steps S114 and S116, the information registration module 40 sends the evaluation contents to the terminals of the parties related to the related model (specifically, those who are involved in designing the same part of the same device (different model)). Distribution, or distribution to parties of the same model (specifically, those who are involved in the design of another part of the same device (same model)). This distribution has the significance of notifying the above parties of the digest version of the evaluation content in a timely manner and disseminating the defect information.

  Next, detailed registration processing on the designer terminal 10 and processing for standard revision on the administrator terminal 12 that can be performed in parallel with the processing of FIG. 17 and FIG. It demonstrates along a flowchart.

  First, in step S120 of FIG. 19, the information registration module 40 determines whether or not detailed registration has been performed by the designer. In this case, the detailed registration is, for example, selecting a failure reason list or an image list (an image obtained by photographing the failure portion) registered in the past information DB in advance so as to substantially match the currently occurring failure. Means to register the image. If the determination here is affirmed, the process proceeds to processing on the administrator terminal 12 side. If the determination is denied, the process proceeds to step S122 to determine whether or not the delivery date has passed. If the delivery date has not passed at this stage, the process returns to step S120, and if there is no detailed registration, steps S120 and S122 are repeated until the delivery date has passed.

  If the delivery date has passed, the determination in step S122 is affirmed, so the information registration module 40 issues a warning to the designer terminal 10 in step S124. Even in this case, as a warning method, a direct warning display on the screen may be adopted, warning information is distributed via e-mail or the like, a warning sound is output via a speaker, or these Combinations may be employed.

  After performing the warning as described above, the information registration module 40 waits until detailed registration is performed in step S126, and at the stage where the detailed registration is performed from the designer terminal 10, the administrator terminal 12 side Move on to processing.

  In the next step S140, the information registration module 40 instructs the administrator to analyze the defect via the administrator terminal 12.

  In response to the instruction, the administrator executes (1) analysis of the cause of the failure, (2) analysis of the process in which the failure has occurred, and (3) analysis of the association between the change contents and the failure information. By these analyses, the administrator can create the details of the defect information as shown in FIG.

  Therefore, the information registration module 40 waits until the association between the change contents and the defect information necessary for creating details of the defect information to be confirmed at the time of design examination is registered in step S142 in FIG. When the registration is performed by the above, the process proceeds to the next steps S144 and S146.

  In these steps S144 and S146, the information registration module 40 uses the contents of the association registered in step S142 to be related to the related model (specifically, those who are involved in the design of the same part of the same device (different model)). ) Or to a related person of the same model (specifically, a person who is involved in the design of another part of the same device (same model)). This distribution has the significance of notifying the relevant parties of the digest version of the associated content in a timely manner and disseminating the defect information.

  In the next step S148, the information registration module 40 determines whether or not the status of the change content is a record OK. In this case, the result status is basically “result OK” (because it is assumed that the result is OK in step S46 of FIG. 4), and therefore the status needs to be changed to the result NG. Therefore, when the determination here is affirmed, in step S150, the information registration module 40 changes the status of the change content to the actual result NG, and the process proceeds to step S152. If the determination in step S148 is negative, the process directly proceeds to step S152.

  Thereafter, in step S152, the defect occurrence rate is changed, and the entire process of FIG.

  Here, the defect occurrence rate will be specifically described. As shown in FIG. 20A, the defect occurrence rate includes “non-standard NG rate” and “non-standard OK rate” set for each part and each dimension. Here, as shown in FIG. 14A, the “standard NG rate” is the standard 54 set for each dimension of each part (in FIG. 14A, as an example, the dimension A of the part β This means the ratio at which the occurrence of a defect was confirmed even though the standard value was set within the range of 0.5 mm to 1.5 mm. The “non-standard OK rate” means a ratio in which the occurrence of a defect was not confirmed even though a value outside the standard 54 range set for each dimension of each part was set as an examination value. To do.

  Next, the standard revision process using the above-described defect occurrence rate will be described with reference to the flowchart of FIG. The process of FIG. 21 is executed by the score data management module 46 of the application server 18 of FIG. 2 based on an input from the administrator on the administrator terminal 12.

  First, in step S170, the score data management module 46 determines whether or not the standard NG rate is equal to or greater than a threshold value. Here, for example, the standard NG rate is 25% and exceeds a threshold value (for example, 20%), and therefore the determination in step S170 is positive.

  Next, in step S174, the score data management module 46 notifies the administrator terminal 12 of a standard revision review request. In this case, the score data management module 46 displays a standard revision screen as shown in FIG.

  Next, the score data management module 46 waits until an item for standard revision is selected in step S176. In this case, for example, as shown in FIG. 20B, the administrator performs the selection by placing the mouse pointer on the part β and clicking.

  If the determination in step S176 is affirmed, in step S178, the score data management module 46 displays details about the selected item (part β) as shown in FIG. The contents of FIG. 22 correspond to the contents of the list of FIG.

  Next, in step S180, the score data management module 46 revises the standard item by, for example, clicking the column of the NG rate within standard (the column displayed as 25% as an example) in FIG. Determine whether the administrator has determined that there is a need for If the determination here is negative, there is no need for standard revision, and all the processes in FIG. 21 are terminated.

  On the other hand, if the determination in step S180 is affirmative, the process waits until the correction of the standard item is completed in step S182. The administrator can appropriately change the standard of dimension A (the column described as “0.5-1.5”) on the screen of FIG. For this reason, the administrator can input a narrow range in which the standard NG does not occur in the standard column (for example, 0.5 mm to 1.0 mm can be input again in the standard column). . When the determination in step S182 is affirmed by the above input, the process proceeds to step S184, and the range in which the score data management module 46 re-enters the standard stored in the standard DB 28 in the standard column of FIG. Update to the value of.

  After that, in step S186, the score data management module 46 transmits the update information to the designer, thereby completing the entire process of FIG.

  On the other hand, if the determination in step S170 is negative, the process proceeds to step S172, and it is determined whether or not the non-standard OK rate is equal to or greater than a threshold value (for example, 30%). If the determination here is affirmed, the processing after step S174 is executed in the same manner as described above. Then, the administrator can correct the standard in a direction in which the standard is expanded (a direction in which the standard is expanded so that an examination value that is OK outside the standard is included in the standard). On the other hand, if the determination in step S172 is negative, the process returns to step S170, and the same processing as described above is executed.

  In the above description, when the determination in step S170 is negative, the determination in step S170 is performed, and the nonstandard NG rate is determined in preference to the nonstandard OK rate. This is because the NG rate within the standard is considered to have a relatively large influence on the occurrence of defects, so that the revision is relatively urgent. However, the present embodiment is not limited to this. For example, it may be determined whether or not the non-standard NG rate and the non-standard OK rate exceed a threshold value. It may be determined with priority.

  In addition, in the flowchart of FIG. 17, the case where a designer discovers a malfunction was demonstrated as an example. However, the present invention is not limited to this, and defects may be discovered by, for example, manufacturing process personnel, quality control personnel, evaluation personnel, and the like. Registration may be performed.

  In the present embodiment, the case where the examination value or the standard is a dimension (numerical value) has been described. However, the present invention is not limited to this, and the present embodiment is also suitably applied to the examination of the material of a certain part. be able to. For example, when changing a certain part from Resin X to Resin Y or from Resin X to Resin Z, whether or not a malfunction has occurred is acquired as a performance value, and the standard is revised based on them. Or displaying defect information. In addition, the design support system according to the present embodiment can be suitably applied to the study on various design elements such as the surface treatment method.

  As described above, according to the present embodiment, the registration result distribution module 42 of the application server 18 receives a specification (selection) of a specific part of the product (for example, the dimension A of the part β) by the designer, Since past information such as score data and defect information corresponding to a combination (for example, 0.5 mm → 1.5 mm) of the state before the change and the state after the change when changed is provided to the designer terminal 10. The designer can appropriately determine the changed state of the specific part by referring to the past information. As described above, since it is possible to assist the designer in determining the state after the change of the specific part, it is possible to improve the convenience of the designer (user).

  In addition, according to the present embodiment, the “standard” regarding the contents of the check is revised based on the collected actual value, and therefore, as the collected actual value is new and the number increases, the “standard” is revised to an appropriate value. Is possible. For this reason, the more the designer uses the design support system of the present embodiment, the more the performance feedback is promoted and the PDCA cycle is effectively rotated. Therefore, the standard can be revised to an appropriate value. Further, as the number of collected actual values increases, the reliability related to the defect information provided to the designer based on these actual values also improves. As described above, according to the present embodiment, as the use is repeated, the occurrence of defects is further prevented.

  Moreover, in this embodiment, since the state before the change and the state after the change are displayed as specific numerical values (the past raw data as they are), the designer can use general numerical values that can be used for various devices. There is no need to perform an operation for conversion to a value specialized for the target device as in the case of using it. Thereby, it is possible to design easily.

  According to the present embodiment, the registration result distribution module 42 provides the designer terminal 10 with a plurality of past information such as score data and defect information according to the importance. It is possible to browse past information efficiently, and as a result, product design can be performed efficiently.

  In the present embodiment, the registration result distribution module 42 forcibly issues a warning when the examination value is input without browsing the information with the highest degree of relevance (required confirmation information) among a plurality of past information. Therefore, it is possible to prevent the designer from confirming the past information required at the minimum for determining the examination value. Thereby, it is possible to reduce the rate of occurrence of defects.

  Further, in the present embodiment, the standard DB 28 holds a standard (reference range information) for each part of the product, and the score data management module 46 is based on past results (in-standard NG rate and non-standard OK rate). Thus, since the standard is revised, an appropriate standard (reference range information) according to past results can be stored in the standard DB 28 at all times. In addition, it is possible to make appropriate revisions such as revising the standard to narrow the standard when the non-standard NG rate is relatively high, and revising the standard to widen the standard when the non-standard OK rate is relatively high. It is. Note that the standard revision is not limited to expanding or narrowing the range as described above, but changing the upper and lower limits while keeping the standard range constant (slide the standard range width). You may make it do.

  In the above embodiment, as an example, a design support system including a plurality of PCs and the like as illustrated in FIG. 1 has been described. However, the embodiment of the present invention is not limited to this, and the above embodiment is described. The design support apparatus may be configured by one information processing apparatus that includes the functions of the application server 18, the database server 16, and the designer terminal 10 described above.

  Note that some of the processing sequences described in the above embodiments have been left to the designer, administrator, registrant, etc., but some of them may be executed by a PC or server. For example, in FIG. 21 of the above embodiment, when the standard NG rate or the non-standard OK rate is equal to or higher than the threshold (steps S170 and S172), the administrator terminal 12 is notified (provided with revision information), Based on the notification, the administrator determines whether or not to revise and decides to change the standard. However, when the standard NG rate or the non-standard OK rate is equal to or higher than the threshold (steps S170 and S172). The score data management module 46 may automatically change the standard so that the defective part is not included. When such processing is performed, the standard may be determined only when the administrator approves the automatically changed standard.

  In the above embodiment, as an example, the application server 18, the database server 16, and the terminals 10, 12, and 14 are configured as separate devices, but a computer system is configured by combining a CPU, a ROM, a RAM, and the like. It is also possible to realize the functions of the above-described devices by a program built in the computer system and a storage medium storing the program.

  Each embodiment mentioned above is an example of suitable implementation of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.
