Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design support apparatus that uses a computer system equipped with a design program to design a plant product or the like on the basis of specification information representing product specifications.

[0002]

2. Description of the Related Art In designing a current plant product or the like, a design support apparatus composed of a computer system having a design program is used. The designer designs while referring to the user requirement specifications (for example, specifications) that represent the specifications of the product provided by the user, and the specification information composed of the survey information obtained from the survey work (usage situation survey) for the user. Operate the support equipment to design products that meet specifications.

FIG. 8 shows an example of such a conventional design support apparatus, and FIG. 9 shows a flow chart when a design is carried out using the design support apparatus shown in FIG. Is. A design method using a conventional design support apparatus will be described below with reference to FIGS. 8 and 9.

First, the designer 100 of FIG. 8 who designs the plant control system, that is, the control software, performs a meeting with the user 300 in step S21 of FIG.
A user requirement specification / usage status 301 (D21 in FIG. 9) in FIG. 8 describing what functions are required is obtained by the user hearing and the investigation of the user usage status. Then, in step S22, the designer 100 operates the system design support means 210 in the man-machine system design support apparatus 200 that mainly designs the software of the product by using the user requirement specifications / usage status 301, Function of·
A system design for designing specifications is executed to create a system specification D22 in FIG.

This man-machine system design support means 20
0 designs a product system (software) based on plant design information, that is, use environment information and specification information such as specification purpose information. This software is, for example, performance design support software, plant model production software,
It also means failure diagnosis knowledge creation support software.

If the system can be designed in this way, the designer 1
In step S23, the screen design support means 220 designs the screen for each of the plurality of functions. The screen design support means 220 refers to the system design information output from the system design support means 210 to design the display information displayed on the display device during the plant operation. At the same time, the screen specification D23 is created and displayed on the screen design display means 221. Therefore, since the display screen can be presented to the user at this stage, the user 300 is requested to perform the primary evaluation of the design content in step S24 based on the display content. Then, the user primary evaluation result D24 in FIG. 9 is obtained.

Then, in the next step S25, the designer 100
The user 30 according to the user primary evaluation result D24.
Whether or not there is a change request by 0 is determined. This result is YES
In the case of, the processing returns to step S22 or step S23 depending on the changed content. That is, if the changed contents relate to the system design, the process returns to step S22, and if the changed contents relate only to the screen design, the process returns to step S23. That is, the system designer 100 can appropriately change the design content according to the request from the user 300. Then, by repeating the above description, when the result of step S25 is NO (that is, when there is no change request from the user 300), the prototype making support means 230 is started at step S26, and the designer 100 performs the demo for the user. Prototype production capable of simulating actual screen operation is executed, and at the same time, a prototype verification report D25 showing the contents of the prototype is generated.

The prototype production support means 230 is
A prototype of the product 500, for example, a simulation device is manufactured by referring to the system design information and the display information. This simulation device includes a switch, a logic circuit that represents a valve, and the like that are actually operated by a staff member. The production result by the prototype production support means 230 is a prototype display that is a display device that displays the prototype as image information. It can be displayed on the means 231. Therefore, the user 300 can virtually recognize the completed state of the product 500 based on the display content of the prototype display means 231. Therefore, in step S27, the designer 100 based on the display content of the prototype display means 231. The user 300 is requested to carry out the secondary evaluation of the design contents. Then, the user secondary evaluation result D26 in FIG.
To get

Then, in the next step S28, the designer 100
Is the user 30 according to the user secondary evaluation result D26.
Whether or not there is a change request by 0 is determined. This result is YES
In the case of, the processing returns to step S22, step S23, or step S26 depending on the changed content. That is, if the changes are related to the system design, the process is step S2.
Returning to step 2, if the screen design other than the system design is involved, the process returns to step S23. Also, if the changes are related to prototype production other than system design and screen design,
The process returns to step S26.

And repeating the above description,
If the result of step S28 is NO, that is, if the prototype has been approved by the user 300, the system design support device 200 in FIG.
00 is manufactured, and the product creator 400 manufactures the product 500 based on the output manufacturing information.

[0011]

The above is the outline of the operation of the conventional design support apparatus. In the design using this conventional design support apparatus, the design information is interpreted at the discretion of the designer 100 and the design is performed. Since the information has been executed, the degree of fulfillment of various information generated in the design process, for example, the degree of fulfillment that complies with the understanding of the information receiving side (user), may not be produced in the set information. That is, even if there is only one piece of specification information, different design results may be executed in the generation of various kinds of information and the production of prototypes, depending on the skill of the designer 100 and the degree of understanding of the specification information.

For example, when a plurality of designers cooperate to execute a work, the process is divided into a plurality of processes, and the plurality of designers cooperate and share the work. When performing such sharing work, if the quality of the information generated differs for each designer, cooperation between the designers will not proceed smoothly. In order to smoothly promote the cooperation between the designers, it is necessary to execute a meeting related to the information in addition to exchanging the generated information. Execution of such meetings has led to a reduction in work efficiency.

Further, there is a possibility that the relationship between the contents of the specification information and various kinds of generated information, that is, the information whose design basis is not clear is generated as the work is executed. In addition,
If this relationship is ambiguous, and if the user is asked to explain which function on the prototype the content specified in the specification information corresponds to, the explanation cannot be given and the prototype design is executed again ( There is a risk that the work will be forced.

Although this conventional design support device has the effect of improving the quality of the product, in the recent man-machine system design, a design for "manufacturing" that meets the user's request, " Product design that considers "usability" first is required, and the design process necessary for that is defined in ISO13407 "system human-centered design process" standard and the like. This requires the following in order to determine the function and operation procedure desired by the user based on the user's own voice rather than the designer's imagination. a) Actively engage users and have a clear understanding of user and task requirements. b) To properly divide the roles between the user and the system,
The operation of the user and the operation executed by the system are determined in consideration of the ability of the user. c) Repeat design and evaluation, and reflect the user's opinion to redesign the design many times. d) Include experts from various disciplines, such as engineers and planners, as well as end users, product buyers, ergonomics experts in the design team and incorporate the designs of these people. .

In order to execute this, this ISO1
In 3407, the following four are required to be incorporated into the design process. 1) Understand the usage situation of what kind of user and under what circumstances. 2) A description of the user's request in this usage situation. 3) Creating a design proposal based on the request of this user. 4) Evaluation by the user of the design and determination of whether the requirements are satisfied.

However, in order to proceed with the design according to this process, there are the following current problems as described above. That is, in ISO13407, it is necessary to use a checklist to determine whether or not the standard is met, and to leave necessary information as a document at each design stage so that it can be accessed later. There is no clear definition of what to do. Therefore, 1. The design procedure and the contents of documents created in each process differ depending on the designer and the system and have not been standardized, which poses a problem in terms of work efficiency. In particular, it was difficult to prepare standard information and documents required for each ISO13407 standard certification process. 2. Since the connection of design results between each process is unclear, the relationship between the user request that is the basis of the design and the user usage status survey result and the design result in each process is ambiguous, and the user request is not sufficiently satisfied, In some cases, the design from the user's point of view was not made from the viewpoint of central design. 3. Also in system evaluation, it was difficult to evaluate from the viewpoint of user request and confirm the consistency with the modification contents. 4. Documents required for ISO13407 standard certification include IS
Many of the documents prepared by the O9000 standard certification can be reused, but the connections between these documents are unclear and cannot be fully utilized.

In view of such a point, the present invention can set the design content appropriately corresponding to the specification information output from the user without being influenced by the skill of the designer, and further, the specification information and the design can be set. It is an object to provide a design support device capable of clarifying the relationship of contents and supporting the design according to the design process of the ISO standard and the creation of necessary documents.

The survey / confirmation items required for each course were standardized for each target plant or system, and a tool was created to facilitate input / recording.

Then, the extracted and recorded user requirement items and the correspondence information between the requirements and each design item are satisfied with the above-mentioned fourth design process in ISO13407, 4) the evaluation and the requirement by the user of the design. Judgment of whether there is. Incorporated as an evaluation item in, and made into a tool as an evaluation tool combined with other general evaluation items.

The screen design support means 220 refers to the system design information output from the system design support means 210 and the screen design specification information (second correspondence information) output from the user request / screen correspondence definition support means 246. Then, the display information displayed on the display device during the plant operation is designed. The screen design display means 221 is the screen design support means 22.
0 is a display device for displaying designed display information. The screen design display unit 221 can be used when presenting display information to the user 300.

The prototype production support means 230 refers to the system design information and display information and the logic information output from the user request / logic correspondence definition support means 247 to produce a prototype of the product 500, that is, a simulation device. .. This simulation device includes a logic circuit and the like that represent switches and valves that are actually operated by a staff member. The prototype display unit 231 is a display device that displays the prototype of the product 500 manufactured by the prototype manufacturing support unit 230 as image information. The user 300 can virtually recognize the completed state of the product 500 based on the display content of the prototype display unit 231.

Next, the operation of the first embodiment of the design support apparatus according to the present invention shown in FIG. 1 will be described with reference to the flow chart of FIG. First, the designer 100 conducts a meeting with the user 300 in step S1, collects specification information by conducting a user hearing for design clarification and a user usage status survey. And designer 10
Reference numeral 0 denotes a user definition support means 241, a plant definition support means 242, a system definition support means 243, and a goal task analysis support means 24 that constitute the design basis clarification means 240.
4, user definition, plant definition, system definition,
Goal task analysis is performed, and based on the result of this execution, the user request / system function correspondence definition support means 245 provides the first correspondence information to the user request / screen correspondence definition support means 2
46 generates screen design specification information (second correspondence information), and user request-logic correspondence definition support means 247 generates logic information (third correspondence information). Analysis result) D1.

Then, the designer 100 proceeds to step S2.
Then, the system design support means 210 of the system design support apparatus 200 is operated to execute the system design based on the clarification of the design basis to generate the system specification D2. Since this system design is executed with reference to the first correspondence information generated by the user request / system function correspondence definition support means 245, there is no case where the relationship between the specification information and the design content becomes unclear. The system specification D2 clearly describes the relationship between the specification information and the design content.

When the design by the system design support means 210 is completed in this way, next in step S3, the screen design based on the clarification of the design basis by the screen design support means 220, that is, the generation of the image information is executed, and at the same time, the screen specification D3 is generated. Made This screen design is screen design specification information (second screen) output from the user request / screen correspondence definition support means 246.
Corresponding information) is referred to, so the user-requested specifications are reflected as they are. It should be noted that the screen at this stage is not completed as a system, but refers to a screen for merely inputting and displaying results. Further, in the screen specification D3 created at the same time, the relationship between the specification information and the screen information is clearly described. The design screen designed by the screen design support means 220 can be displayed on the screen design display means 221, so that the designer 100 can design the screen design display means 2
In step S4, the user 30
Request 0 for primary evaluation of design contents based on clarification of design basis. Therefore, the user 300 looks at the design screen and evaluates whether it meets the required specifications, and sets the result as the user primary evaluation result D4.

Then, the designer 100 refers to this user primary evaluation result D4 in step S5, and judges whether or not there is a design screen change request from the user 300. If the result of step S5 is YES (that is, there is a change request), the process returns to step S2 or step S3 depending on the content of the change. When the changed contents relate to the system design, the process returns to step S2, and when the changed contents relate only to the screen design, the process returns to step S3. When the result of step S5 is NO (that is, there is no change request) by repeating the above description, the prototype making support means 230 is activated in step S6, and the designer 100
Prototype production based on the clarification of the design basis that allows actual screen operations to be simulated for user demonstration is executed, and a prototype verification report D5 showing the contents of the prototype is generated.

Since this prototype is produced based on the logic information (third correspondence information) generated by the user request / logic correspondence definition support means 247, the user request specifications are reflected as they are, and the prototype is generated at the same time. In the verification report D5, for example, the relationship between the specification information and the logic is specified. The production result by the prototype production support means 230 is the prototype display means 23.
Therefore, the designer 100 requests the user 300 to perform the secondary evaluation of the design content based on the clarification of the design basis in step S7 based on the display content of the prototype display unit 231. Therefore, the user 300
The prototype displayed on the prototype display unit 231 is viewed to evaluate whether it meets the required specifications, and the result is used as the user secondary evaluation result D6.

Therefore, the designer 100 refers to this user secondary evaluation result D6, and determines whether or not there is a prototype change request by the user 300 in step S8. Then, if the result of step S8 is YES (that is, there is a change request), the process returns to step S2, step S3, or step S6 depending on the content of the change. That is, if the changed contents relate to the system design, the process returns to step S2, and if the changed contents relates to a screen design other than the system design, the process returns to step S3. If the changes are related to prototype production other than system design and screen design, the process returns to step S6. Then, by repeating the above description, when the result of step S8 is NO (that is, there is no change request), that is, when the approval of the prototype is obtained, the product 5 by the manufacturer 400 is obtained in step S9.
Production of 00 is executed. By executing step S9,
A product instruction manual D7 representing the content of the product 500 is generated.

In this way, the user request-system function correspondence definition support means 245, the user request-screen correspondence definition support means 246, and the user request-logic correspondence definition support means 247 make the user request specifications consistent data. As shown by 248 in FIG. 2, the relationship between the user request and the system function, screen specification, logic specification, etc. is clarified, and the manufacturing is performed while making use of it in the system design, screen design, and logic design. Specification information in the conventional design support apparatus is not interpreted at the discretion of the designer 100, and different design results are executed in various information generation and prototype production. Even when multiple designers work together, the quality of information does not differ between designers, which facilitates collaboration between designers and improves work efficiency for information meetings. There is no chance of a decline. In addition, the relationship between the contents of the specification information and various kinds of generated information, that is, the design basis, is determined in steps S2, S3, S6.
Since it is clear in the system specification D2, the screen specification D3, and the prototype verification report D5 created in step S4, the system designer 100 sets the user 3 in steps S4 and S7.
When the correspondence relationship between the specification information and the design content is asked from 00, it can be easily explained with reference to these D2, D3, and D5 in which the correspondence relationship is specified.

Generated and the result is shown in Figure 4.
Request specifications (including task analysis results) D1
It becomes 1.

Then, the designer 100 proceeds to step S1.
In step 2, the system design support means 210 of the system design support apparatus 200 is operated to execute the system design based on the clarification of the design basis to generate the system specification D12. Since this system design is executed with reference to the first correspondence information generated by the user request / system function correspondence definition support means 245, there is no case where the relationship between the specification information and the design content becomes unclear. The system specification D12 clearly describes the relationship between the specification information and the design content.

When the design by the system design support means 210 is completed in this way, next in step S13, the screen design based on the clarification of the design basis by the screen design support means 220,
That is, the generation of the image information is executed, and at the same time, the screen specification D1
3 is made. This screen design is performed by referring to the screen design specification information (second correspondence information) output from the user request / screen correspondence definition support means 246, so that the user request specifications are reflected as they are. It should be noted that the screen at this stage is not completed as a system, but refers to a screen for merely inputting and displaying results. Further, in the screen specification document D13 created at the same time, the relationship between the specification information and the screen information is clearly described. The design screen designed by the screen design support means 220 can be displayed on the screen design display means 221, so that the designer 100 designs the user 300 in step S4 based on the display content of the screen design display means 221. Request the primary evaluation of the design contents based on the clarification of the rationale.

In this evaluation, first, the designer 100
A manager, a quality manager on the designer side, and an evaluator 600 such as a user or a third-party evaluator operate the evaluation sheet creating unit 251 in the evaluation supporting unit 250 to obtain each required specification regarding the screen. , Create an evaluation sheet that is a list of other items related to user requests. Then, the evaluation sheet is presented to the user 300, and the user 300
Sees the evaluation sheet and the design screen, evaluates whether or not it meets the required specifications, and sets the result as the user primary evaluation result D14. When the evaluation is completed, the evaluator 6
00 operates the user evaluation extraction support means 252 based on this user primary evaluation result D14, how the items listed on the evaluation sheet are reflected, and whether the user is satisfied with the reflected result, etc. The evaluation result is input and is output by the evaluation result output means 253. On the other hand, the designer 100 digitizes the primary evaluation content of the user based on the data D14, and requests the digitized evaluation content from the user.
It is stored in the inter-screen correspondence definition support means 246.

Next, the designer 100 refers to this user primary evaluation result D14 in step S15 and judges whether or not there is a design screen change request from the user 300. If the result of step S15 is YES (that is, there is a change request), the process returns to step S12 or step S13 depending on the content of the change. When the changed contents relate to the system design, the process returns to step S12, and when the changed contents relate only to the screen design, the process returns to step S13. Then, by repeating the above description, when the result of step S15 is NO (that is, there is no change request), the prototype production support means 230 is activated in step S16, and the designer 100 performs the actual screen operation for the user demo. The prototype production based on the clarification of the design basis that can be simulated is executed, and the prototype verification report D15 showing the contents of the prototype is generated.

Since this prototype is produced based on the logic information (third correspondence information) generated by the user request / logic correspondence definition support means 247, the user request specifications are reflected as they are, and at the same time, the prototype is generated. In the verification report D15, for example, the relationship between the specification information and the logic is specified. The production result by the prototype production support means 230 is the prototype display means 2.
31 and therefore the designer 100
Based on the display content of the prototype display unit 231, the user 300 is requested in step S17 for the secondary evaluation of the design content based on the clarification of the design basis.

This evaluation is the same as the primary evaluation.
00, a quality manager on the designer side, and an evaluator 600 such as a user or a third-party evaluator operates the evaluation sheet creation unit 251 in the evaluation support unit 250 to display the system function / screen. -Create an evaluation sheet that is a list of each requirement specification related to correspondence between logics and each item related to user request, and present the evaluation sheet to the user. Therefore, the user 300 looks at the prototype and the evaluation sheet displayed on the prototype display means 231, evaluates whether or not they meet the required specifications, and sets the result as the user secondary evaluation result D16. When the evaluation is completed, the evaluator 600 operates the user evaluation extraction support means 252 based on the user primary evaluation result D16,
Evaluation results such as how the items listed on the evaluation sheet are reflected and whether the user is satisfied with the reflected results are input and output by the evaluation result output means 253. On the other hand, the designer 100 quantifies the primary evaluation contents of the user based on the data D16, and the quantized evaluation contents are user request-logic correspondence definition support means 247.
To store.

Therefore, the designer 100 refers to this user secondary evaluation result D16, and determines whether or not there is a prototype change request by the user 300 in step S18. If the result of step S18 is YES (that is, there is a change request), the process proceeds to step S12 according to the content of the change,
The process returns to step S13 or step S16. That is, if the changes are related to the system design, the process is step S.
Returning to step 12, the process returns to step S13 if the changed content relates to a screen design other than the system design. If the changed contents relate to prototype production other than system design and screen design, the process returns to step S16. Then, the above description is repeated, and the result of step S18 is N.
When it becomes O (that is, there is no change request), that is, when the approval of the prototype is obtained, the production of the product 500 by the producer 400 is executed in step S19. By executing step S19, a product instruction manual D17 representing the content of the product 500 is generated.

In this way, the user request / system function correspondence definition support means 245, the user request / screen correspondence definition support means 246, and the user request / logic correspondence definition support means 247 make the user request specifications consistent data. As shown by 248 in FIG. 4, the relationship between the user request and the system function, the screen specification, the logic specification, etc. is clarified, which is utilized in the system design, the screen design, the logic design, and by the evaluation support means 250. As shown by 254 in FIG. 4, the manufacturing is performed by being utilized also in other user evaluations such as check items and trial results based on evaluation items related to general evaluations and user requests. The specification information is interpreted at the discretion of the designer 100, and various information is generated and prototypes are created. Made design result is performed, it is eliminated as called. Even when multiple designers work together, the quality of information does not differ between designers, which facilitates collaboration between designers and improves work efficiency for information meetings. There is no chance of a decline. Further, the relationship between the contents of the specification information and various generated information, that is, the design basis is the system specification D created in steps S12, S13, and S16.
12, screen specification D13, prototype verification report D1
5, the system designer 100 refers to these D12, D13, and D15 in which the correspondence is specified when the correspondence between the specification information and the design content is asked by the user 300 in steps S14 and S17. Can be easily explained.

Further, the system designer 100 can recognize the comprehensive evaluation of the design result based on the output of the evaluation result output means 253, and the storage of the evaluation result output unit 253 of the evaluation support means 250, for example. By storing the evaluation result in the device, it is possible to reflect the user's request when executing the subsequent design. In this case, the design can be executed with special consideration given to the user's unique requirements and points of interest.

As described above, the design support apparatus according to the present invention objectively analyzes the specification information output from the user, and determines the design contents based on the analysis result. It is possible to avoid a situation in which different design results are produced depending on the. Further, since the correspondence relationship between the analysis result (specification information) and the design content can be stored, when the user requests the clarification of the basis of the design content, the correspondence relationship can be referred to and the explanation can be made quickly. ..

Next, a third embodiment of the design support apparatus of the present invention shown in FIG. 5 will be described.
