2. Description of the Related Art For example, when introducing a new model in a factory for assembling vehicles, when a process designer can form a new production line according to the new model, the order of work on this production line It is important to arrange the parts and work necessary for assembling the vehicle, and the work time thereof, and to organize an optimum work process table for leveling each work process. For this purpose, a process information management method and device are required. Various proposals have been made.

FIG. 8 is a procedure diagram for explaining a conventional method for organizing and managing work processes. Referring to FIGS. 8A and 8B, this conventional method first refers to each assembly drawing which is a partial assembly drawing of a vehicle, describes the element work of the vehicle assembly in a derived type, forms an element work record, and files the work. Each element work record is classified and summarized for each process number, which is the smallest unit in the organization, and a work process table is created by arranging them in time series in the order of work, and each work process table is arranged in order of process number along the flow of production. The process organization 1 in which the production lines are assembled in combination is executed.

Next, following the process organization 1, the process evaluation 2 for comprehensively evaluating the necessity of reorganization, and the work man-hours of the work process table are totaled to approve the validity and each work process table. Is printed and, if necessary, total approval 3 for transferring information to another system SYSA (not shown) is sequentially performed.

In FIG. 9, this device includes terminal devices PC1 and PC2 for the process designer to organize work processes and instruct processing, display devices CRT1 and CRT2 for displaying the process of formation and processing, and work devices. A file server FS having a file memory is connected online via a local area network LAN, and these devices CRT1, CRT2, PC1, L are connected.
A process management system SYS operated by AN and FS is configured, and a preparatory step (not shown) for starting the system SYS is arranged in front of the process organization 1. Incidentally, C, C and C are coupling devices for connecting each device to a LAN.

FIG. 10 is a format diagram showing the information format used in this method. In FIG. 10, analysis information 6 for classifying or searching by the attribute of the work content 5 is added to the work content 5 indicating a specific work on the production line to form an element work record.

The analysis information 6 is obtained by adding a classification key BK for classifying and filed according to the use of the process organization 1 and a search key KK for searching according to the use of the process evaluation 2 to the element work record. I am configuring. The classification key BK is
Use the control number for each assembly diagram and the process number for each work process,
It manages element work files.

However, when the above-mentioned conventional device for managing process information is used to create a work process table while organizing work processes, there are the following problems. . (1) Since a large number of files of element work record groups have to be read into the main memory of the terminal device and then searched, the memory area is squeezed, so that the application program area cannot be sufficiently secured. (2) Further, the process organization, the process evaluation, and the total approval are different, and different terminal devices take a long time to read a large file, and during that time, the terminal device monopolizes the file server. The response capability of the entire system was significantly reduced. (3) Further, this deterioration of the response, together with the complexity of the procedure for instructing the terminal device to perform a search, makes the process designer difficult, so that it is not suitable for an application requiring quickness at the production line site. In view of the above-mentioned problems, the present invention provides a process information search method and apparatus that allows a process designer to search and organize a large amount of process information immediately and easily in a process management system. Is an issue.

[0009]

In order to solve the above problems, the present invention has the following means. (1) Process information for assembling and inspecting multiple types of products on a factory production line is arranged based on the work procedure of the production line to organize a work process table, and the work process table is evaluated and re-processed. In a process management system that can be organized, a classification key is added to the process information to form an element work record, and the element work record is sequentially filed to have a preparation step of forming an element work file. Divide and search sequentially with the classification key, selectively read only the position information of any element work record,
A table tabulation step of repetitively arranging the position information until the end of the element work file is detected and forming a position information table, and the element work file is directly stored by each position information on the position information table. And a record acquisition step of continuously acquiring element work records corresponding to the position information from the element work file in this order. (2) Using the method for retrieving process information described in (1) above, in the tabulation step, the cursor position in the work process table is inspected and obtained, and the element work record at the cursor position is examined. A process information search device comprising a key acquisition process for acquiring the classification key. (3) The classification key is a management number for managing each assembly diagram for dividing and assembling the product and a process number for creating the work process table for each process. The process information search device according to (2) above.
