Finally, a totaling process 46 for totaling the individual man-hours in the element work group arranged in the process table PT and obtaining the total man-hours as a result, and the total man-hours are arranged in a derivation type and arranged. The process evaluation stage 4 is configured by forming the man-hour totaling screen described above, and sequentially providing the display process 47 for displaying on the display device together with the arrayed element work groups, following the array process 45.

Hereinafter, the handling procedure and operation of the apparatus using the method of the present invention will be described in detail with reference to FIGS. 1 to 6. In FIG. 1, in the process organization stage 1, the element work groups searched and classified in the process evaluation stage 4 and displayed in the work process table area WP of the man-hour totalization screen can be arbitrarily reorganized and are organized and unapproved. There is no difference from the conventional process organization stage 1 except that the process evaluation stage 4 can be notified that the element work group of 1 exists in the process table PT.

Further, in the process approval stage 3, it is notified from the process evaluation stage 4 that the approved element work group exists in the process table PT.
There is no difference from the conventional process approval stage 3 except that a predetermined procedure for registering in the server FS is executed. Hereinafter, the description will be given mainly in the process evaluation stage 4.

In FIG. 6, there are two kinds of starting conditions in the process evaluation stage 4, one of which is that the process designer organizes a new work process in the process organization stage 1, and the terminal devices PC1 and PC are connected.
2 is the case where the process table PT has already been created. On the other hand, the process designer selects the process evaluation step 4 directly from the menu screen described above, and the element work file WF registered in the file server FS is evaluated. That is the case.

Only when the former process table PT has been created, a message prompting approval is displayed on the man-hour totalization screen described above. The process designer refers to this message and approves it from the terminal device. It is possible to allow the man-hour management system SYS to execute the process approval stage 3 by inputting the instruction.

At this time, if the user inputs a denial instruction or the created process table PT itself is not held in the terminal device, a message prompting analysis is displayed. Similarly to, the analysis method can be input and instructed, and either the above-mentioned search or classification can be selected.

Then, in the search condition setting process 43a, a search condition setting screen or a classification condition setting screen, which will be described later, for setting the search condition by the search key is displayed according to the selected analysis method. Therefore, the process designer can arbitrarily input either the search key or the classification key, or a combination of both, from the terminal device according to the analysis method to be selected.

FIG. 7 is a diagram showing an arrangement of a totaling condition setting screen for use in the present invention. First, in FIG.
A search method using the search key will be specifically described. On the search condition setting screen, the process designer selects an arbitrary number of arbitrary abbreviations from the menus corresponding to the fields KK1, KK2, and KK3 of the above-mentioned search key, and performs a search showing the logical relationship between these abbreviations. A logical expression is also specified and entered, and this search logical expression is the search condition setting process 4
3a is formed in the search table ST.

Then, when the process designer instructs the completion of all the search key inputs from the terminal device, the search processing 44a actually searches the element work file WF based on the above-mentioned search logical expression, and this is the result. The element work record group is stored in the process table PT by the array processing 45.

Further, in the process table PT, the total number of work man-hours is totaled by the machine type and the derivative type by the totaling process 46, the result is stored in the man-hour table TT, and the work process table area WP is displayed by the display process 47. It is displayed. Therefore, in the specific range of the production line, it is possible to arbitrarily aggregate the work man-hour group spent for the work content having the specific attribute executed at the specific position of the vehicle for the specific element of the vehicle function. .

The above is a specific search method, and the specific classification method is almost the same as this search method except that the classification key is used instead of the search key. Next, the calculation of the work man-hours will be specifically described.

In FIG. 5, the work man-hours displayed in the work type column TK of the derived type are compared with each other in numerical values as a result of the totaling process 46, and the derived work having the maximum work man-hour showing the maximum value of the work man-hours. And the numerical values are highlighted, and the process designer can instruct the process reorganization related to the derived species from the menu displayed in the process instruction column CMD, if necessary.

For highlighting, the maximum value can be obtained even if marking is made with a conspicuous symbol such as an asterisk, or if the font of letters, numbers, or symbols is changed, or inversion display for changing the foreground color and background color is used. What is necessary is that the process designer can identify the derived species and the maximum value at a glance. That is,
The maximum work man-hours of the derived type are calculated for each specific range of the production line, the maximum work man-hours are aggregated over the entire production line to obtain the maximum work man-hours for assembly, and these are displayed in an easy-to-understand manner. Further, the total work man-hours of the derivative type can be calculated for each specific range, or the maximum work man-hour of the derivative type of the derivative type can be calculated for the entire production line, and these are also displayed in an easy-to-understand manner.

When this reorganization is instructed, the maximum man-hour derivative type information, which is information on the maximum work man-hours and the derivative kinds having the maximum work man-hours, and the information on the analysis method are stored in the process organization stage 1.
The element work file WF is searched based on the maximum man-hour derivative type information, and all the work processes of this derivative type are read and displayed on the screen of the display device according to a preset order. The process designer can immediately start updating and reorganizing the work process having the maximum work man-hour.

The present invention is not limited to the above-described embodiment. For example, the approval determination process may be provided after the display process. You may use together with. The element work file may be divided by itself and may be partially transferred to a terminal device for local use if necessary.

If the sequence processing, the totalization processing, and the display processing follow the respective processings in the analysis method,
The mutual execution order may be appropriately exchanged, and the order of each processing in each stage is not limited to this, and as long as the object and the effect of the present invention are met, the mutual execution order may be changed. It may be exchanged. Further, it goes without saying that various modifications can be made without departing from the scope of the present invention, such as the fact that it may be carried out in a general production factory other than vehicle manufacturing.

[0044]

As described above, the present invention has the following effects. (1) The maximum value of the work man-hours in the entire production line can be aggregated into the derived types, and the distribution of the work man-hours can be evaluated in the derived types. Therefore, it is possible to study the deviation of the amount of work required for production by machine type, and to quickly understand the defect in the production line configuration due to this deviation, and in turn, reorganize the work process having the maximum value to detect the defect in advance. It will be possible to correct it and realize an appropriate production line configuration that equalizes the work load for each model. (2) Further, the production line can be divided into arbitrary partial work blocks, the work block having the maximum work man-hour can be selected, and the work man-hour distribution in this block can also be evaluated. It becomes possible to examine the deviation of the work amount on the production line with arbitrary accuracy and level it efficiently. (3) Furthermore, in a compound production line, the production line is divided into work blocks, and the distribution of work man-hours that changes depending on the organization of work processes can be evaluated for each work block by comparing it with the derived type. It is possible to equalize the work amount unevenness due to the difference in the configuration of each species. According to the above (1) to (4), the process designer can immediately and efficiently process and manage the man-hour information in the man-hour information management system of the production factory.
