FIG. 4 shows a work flow for creating and storing a production method for a specific product, and for revising and storing the production method for the product. First, when the client (creator of the production method of the product) creates the production method of the product, the second computer 3 is used, and the procedure (1-1) in FIG. In the "Create" procedure, a process flow diagram (information) similar to the target production method is read from the database 5 by, for example, the classification identification code of the target product (if the products are the same or similar, the process flow diagram is also generally Similar to the desired process flow diagram). The desired one is selected from a plurality of similar process flow diagrams, and then the details of the process are examined according to the process flow diagram. If there is no similar process flow diagram here, the client may create process flow diagram information, and the details of the process may be examined according to the flow diagram. This stage is the procedure of (1-2) “Examination of process contents and creation of process design specifications” in FIG. 4, and the process design specification information, which is detailed information in the order of each process in the process system diagram. Will be reviewed and determined sequentially. The work up to this point is very much accomplished by working according to the sample by using the past data and proceeding with the examination work following the past data by the stratified storage management of the information possessed by the database 5 of the present invention. Efficient work can be performed with less time and effort. Furthermore, the information can be automatically classified and stored by designating all the information according to a predetermined rule by the classification identification code, and can be easily read by designating and inputting the classification identification code even when information is read again. I can do it. This stage of automatic storage and automatic classification is the (2) “storage, DB management” procedure in FIG. The procedures (1-1) and (1-2) are executed by the client by the second computer 3, and the procedure (2) is automatically executed by the program of the first computer 2.
[0020]
If the production method information in the database 5 created next is to be revised according to FIG. 4, the process flow diagram information to be revised in the procedure of (3-1) “Examination of change of process order, revision of process flow diagram”. Are read using the classification identification code. If necessary, information on a predetermined part of the process flow diagram is revised, and a predetermined classification identification code is designated as the information. In order to read out more detailed information, (3-2) Call the process design specification information to be revised in accordance with the process flow diagram in the procedure of “Examination of each process content change and revision of the process design specification”. All related information can be called by the classification identification code of the individual information of the process design specification. Appropriate information is selected from the called information, information to be corrected is corrected in accordance with the information content, and a predetermined classification identification code is designated for the corrected information. Next, (4) the process system diagram information including the process design specification information revised in the “storage, DB management” procedure is automatically classified and automatically stored in a predetermined place. The steps (3-1) and (3-2) are performed by the client by the second computer 3, and the procedure (4) is automatically performed by the program of the first computer 2.
