Abstract
There are provided a repair determination section that determines, based on failure information on the facility for manufacturing a product, a repair time required to repair the facility, and a recovery plan creation section that creates a recovery plan in accordance with a predetermined production evaluation indicator, based on the repair time and production information on a line with the failed facility, one or more other facilities, and on one or more other lines.
Claims18
A production management system for a plurality of lines, each line including a plurality of facilities for manufacturing a product, the system comprising:
- one or more sensors that monitor states of the facilities;
- and
- a production management apparatus that includes:
- a processor;
- a memory that stores program instructions executable by the processor;
- a display apparatus;
- and
- a storage that stores production information, the production information including
- information on the product manufactured on each of one or more of the lines;
- information on a production capacity of each of the one or more of the lines;
- information on a production plan of the product;
- and
- information on a maintenance plan of the facilities, wherein the processor is configured to:
- detect a failure of a facility, of the facilities, included in a line, of the lines, based on data obtained from the one or more sensors to obtain failure information of the facility;
- determine, based on the failure information on the facility a repair method and a repair time required to repair the facility;
- create a production plan change proposal for production of the product that was being produced on the line including the failed facility, in accordance with information on at least one of the production capacity of each line, the maintenance plan of the facilities, progress of the production plan, delivery, and the maintenance plan, and one or more predetermined production evaluation indicators set in advance from among on-time delivery rate, customer importance, man-hours, work hours, labor cost, energy consumption, yield, overall line utilization rate, and quality, the production plan change proposal including
- information as to whether or not and when to repair the failed facility;
- and
- information on at least one of suspension, resumption, or continuation of production on the line including the failed facility, and reallocation of production of the product to an alternative line;
- and
- present, on the display apparatus, the production plan change proposal as a recovery plan according to one or more of the predetermined production evaluation indicators.
