[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design basis recording / retrieval system, and more particularly to a technique for forming a basis document including information indicating a design basis.

[0002]

2. Description of the Related Art Conventionally, in the design work, efficiency has been improved by standardizing design procedures.
However, in the design work, especially in the planning of a plant plan, computerization of the design work has been delayed due to the need for applied skills such as adding or considering circumstances specific to each plant based on past performance. .

[0003] The results of the design work are generally recorded and issued as a calculation report or a review report. In this case, it is necessary to record the process of obtaining the result in the design work, and to enable the verification based on the situation specific to each plant by the record. However, the above recording is not performed on a daily basis, and is not sufficient for improving the efficiency of verification.

On the other hand, with the development of computers in recent years, a system developed in-house or introduced in the market for technical calculation, CAD (Computer Aided Design), drawing management, etc. has been introduced to partially improve the efficiency of design work. It is being done. Furthermore, in the era when one person has one personal computer, office automation between individuals or groups using electronic mail, word processors, spreadsheet software, and the like is progressing. Therefore, by utilizing these infrastructures, information technology (Informat
It is desired to record the process of obtaining the result in the design work by ion technology and to improve the efficiency of the design work including verification.

In response to such demands, for example, the book “Phase of Technical Knowledge” (published by the University of Tokyo) describes a concept called a process model in which the derivation process of design values is expressed by variables, mathematical expressions, grounds, and the like. The technology which can contribute to the efficiency of the design work is shown by adopting and associating the document showing the design basis with the design basis document.

[0006] Also, Japanese Patent Application Laid-Open No. 9-204449 discloses that
A "design work support system" is disclosed. This design work support system records supplementary information such as the reason and basis of design as a shared database, and provides information on the requested supplementary information to the client via the electronic bulletin board server.

Japanese Patent Application Laid-Open No. 9-259157 discloses that
"Design support system" is disclosed. This design support system manages the data necessary for the design, the design basis (design background information) and the design result (product data) through the life cycle, makes them available at the time of design, and makes the related products and / or parts By having the information, the distribution destination of the information at the time of design change is clarified, and automatic transmission is performed.

Further, Japanese Patent Application Laid-Open No. 9-282352 discloses that
"Co-design support system" is disclosed. This collaborative design support system notifies the designer in charge of the occurrence of a conflict between design result data reliably and quickly, and furthermore, the conflict is easily and quickly resolved.

[0009]

However, any of the above-mentioned conventional systems merely has a function of simply associating a document as a design basis with a design basis document.
It is not sufficient to express the basis of the design of a large and complex system, such as a plant, so that the design can be verified later.

[0010] Further, if the same designer needs to review the design as the design phase progresses, if the designer forgets a place previously referred to or changes the designer. Often, the basis of the design of the predecessor is unknown. Therefore, it takes a lot of time to search and confirm materials at the time of reviewing the design, which hinders efficient design. In addition, there is a problem that specifications are inconsistent because the intention of the predecessor is not transmitted correctly.

It is an object of the present invention to provide a design basis recording / retrieval system which can associate a wide range of information serving as a basis for a design with a design basis and can easily verify a design result. is there.

[0012]

In order to achieve the above object, a design basis recording / retrieval system according to the present invention comprises: a plurality of process models expressing a process of deriving a design result;
A network connecting the plurality of process models.

According to the design basis record / search system, for example, the pressure and temperature used in a plant
Since a process model expressing the process of deriving various specification values obtained as a design result (for example, calculation formulas, application to diagrams and the like) is expressed as a network, various information can be extracted from the network.
A network connecting the plurality of process models forms a design basis.

In this design basis record / retrieval system, each of the plurality of process models has an input, a process, and an output for expressing a process of deriving the design result, and an output of a certain process model is different from another. It can be configured to be connected to the input of the process model by the network.

Each of the plurality of process models has an input (for example, design conditions), a process (for example, calculation) and an output (for example, specification value), and the specification value obtained by a certain process model is input to the next process model. Connected to be used as. For example, the pressure obtained by fitting a diagram with a certain process model is input, the flow speed is calculated, the flow speed is obtained, and output to the input of the next process model. With this configuration, a network expression in which the input and output of the process model are linked is possible.

In this design basis record / search system, the input, processing and output can be arbitrarily set. With this configuration, the designer can make up the grounds while clarifying the grounds. In addition, if the same designer needs to review the design, if the designer forgets the part that he referred to in the past, or if the designer changes, the basis of the design of the predecessor is unknown. Even if a situation occurs, the design basis can be easily searched and confirmed by the operation of tracing the basis document expressed in the network, so that the design efficiency can be improved. Further, the conventional problem that the intention of the predecessor is not transmitted correctly and the specification is inconsistent is solved. Further, the network-written basis can serve as a design guide for a designer other than an expert.

Further, in this design basis recording / retrieval system, the input may include information representing a physical quantity and design conditions. Further, the output can be configured to include information indicating a physical quantity.

Further, in this design basis recording / retrieval system, each of the plurality of process models can be configured to include information representing the basis of the judgment of determining the output with respect to the input.

According to this configuration, in addition to expressing the input and output of the process model as a network, the designer's judgment regarding the process model can be expressed as a design basis. For example, information for allowing a margin in the numerical value of the calculation result, information indicating that the numerical value of the previous plant is tentatively cited, and the like can be expressed.

Further, in this design basis recording / retrieval system, each of the plurality of process models may be configured to further include information linked to a document on which the output is determined with respect to the input. .

According to this configuration, a document contributing to the designer's decision regarding the process model can be confirmed by referring to the link destination. For example, the used chart can be referred to on the screen by using the hyperlink function.

Further, the design basis record / search system includes means for outputting a list of process models using the variables by designating the variables used in each of the plurality of process models. It can be further provided. According to this configuration, it is possible to easily determine the process model affected by the design change.

As described above, according to the design basis recording / retrieval system according to the present invention, the work and history are recorded while designing, and the person or a third party later looks at the work and records the design work. The process can be understood (traced) by referring to each process model in the grounds.
