Abstract

PROBLEM TO BE SOLVED: To improve the labor efficiency of facility stopping, work by displaying such an item that becomes to require adjustment, based on the judgment of a human being on a screen as a work schedule list and, at the same time, arbitrarily displaying a movable period on the screen. SOLUTION: The constraint date and constraint content on a inputted item are extracted (2) and held based on the conditional information (1) and, at the same time, the constriction is checked and the constraint date and the reason of the date extracted in the course of checking are held (3). The coordinates of the displaying position of the date of the item which is decided as requested and contained in a facility stoppage requesting plan on a screen are generated (4) and the coordinates of the displaying positions of the items which are decided by manual adjustment and automatic adjustment on the screen are generated (5). In addition, the coordinates of the displaying position of an extracted and held constraint date on the screen are also generated (6). Thus, the constraint date of each item is displayed on the screen of a display as a schedule list, based on the coordinates generated for each item.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility stop work plan support apparatus used for preparing and changing an execution plan of a work performed while stopping facilities of a power system.

[0002]

2. Description of the Related Art In a conventional equipment stop work plan supporting apparatus for preparing an execution plan for a work to be performed while stopping equipment in a power system, usually, mutual requests of work requests are made in accordance with constraint knowledge stored in advance as a knowledge base. The schedule was automatically adjusted, and subjects for which constraint violations could not be resolved were manually adjusted, and were manually adjusted by the person in charge.
Further, when the person in charge tries to manually adjust the subject and designates a moving date, a restriction judgment on the moving date is performed. That is, in the case of the manual adjustment, the presence or absence of the restriction and the possibility of the movement cannot be determined unless the operation for designating the movement date is performed. For this reason, when performing the schedule adjustment work for the equipment stop work plan request, the mutual restriction between the period restriction based on the constraint knowledge for each request and all other request subjects whose schedules have already been determined is performed by brute force. Is performed. A method is used in which the constraint dates extracted in the process and the reasons thereof are held, and dates that cannot be moved for schedule adjustment are displayed on a one-year calendar as required.

[0003]

However, the above-mentioned conventional apparatus uses a method of displaying a date that cannot be moved for the schedule adjustment on a one-year calendar, and thus a dedicated device for displaying the date is used. Needed a screen. Therefore, when performing an input operation for manual adjustment, it is necessary to confirm the date that cannot be moved on the calendar screen and then return to the screen for entering the date to be moved, which is cumbersome and reduces work efficiency. there were.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a method in which, when a request for a task to be performed while stopping equipment is input for each subject, a constraint stored in a knowledge base in advance. Based on the knowledge, the restriction date and restriction contents for the subject are extracted and stored, and the mutual restriction between the input request subject and all the other request subjects whose schedules have already been determined is checked by brute force. After that, they adjust each other's schedule and automatically create a work plan, and at the same time, hold the constraint dates and their reasons extracted during the constraint check process, and also request subjects that cannot be automatically adjusted For the equipment stop work plan support device, which changes the work plan based on the instructions input by manual operation and creates a work plan for the work to be performed by stopping the power system equipment In addition, the coordinates of the screen display position are created from the date of the work plan created for each request subject, and the coordinates of the screen display position are created from the date of each extracted and retained constraint. Keep it. Here, when an input operation for designating the display is performed, the coordinates of the designated subject or the date of the constraint are called from the coordinate holding means, and the designated contents are displayed on the screen in the form of a schedule list based on the coordinates.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The hardware configuration of the embodiment described below includes a computer main body, a CRT display, a storage device for storing a knowledge base and the like, an input / output device, and the like. I have. FIG. 1 is a configuration diagram conceptually showing the processing functions of the present invention.
When a request for an operation to be performed while the equipment is stopped is input for each subject, the constraint date and the content of the constraint are extracted and held based on the previously prepared constraint knowledge ().

Next, a mutual constraint between the input request subject and all the other request subjects whose schedules have already been determined is checked by brute force, and the constraint date extracted in the process and the reason therefor are checked. Hold(). Then, among the proposed equipment stop requests, the coordinates of the screen display position for the date of the subject determined as requested are created (), and the subject determined by the manual adjustment and the subject determined by the automatic adjustment are also generated. Create screen display position coordinates for date (). Furthermore, the coordinates of the screen display position for the extracted and held constraint date are created (6). In this way, based on the coordinates created for each subject, the restriction date for each subject is displayed as a schedule list on the CRT display ().

FIG. 2 shows an example of a work suspension plan creation screen displayed on the CRT display. In the illustrated example, the screen 21 displays a stop facility requesting work execution, a schedule, a work summary, and the like. By selecting the display list 22 of the stopped facilities on this screen 21 with the mouse, and then selecting "display" 23 in the "restriction" pull-down menu, the restriction period for the subject is shaded in the display section. Shown as 24. Although not shown in the drawing, a common constraint period that does not depend on each subject and a constraint period that is unique to each subject are displayed in different colors. As described above, in the embodiment of the present invention, the restriction period for each equipment stop request plan is displayed on the screen 21 by a simple mouse operation.
Since it is displayed as a schedule table above, when manually adjusting the schedule for a plurality of work requests, the screen operation for checking the restriction period is simplified, and the workability is improved.

[0008]

As described above, according to the present invention, a subject that needs to be adjusted by human judgment is displayed on the screen as a work schedule list because adjustment by the automatic adjustment function is impossible. In addition, it is possible to arbitrarily display a movable period. As a result, in the process of adjusting a large number of equipment stop work plan requests, it is easy to grasp the movable period of each request, so the number of screen operations during manual adjustment is reduced, and the work efficiency is greatly improved can do.
