Production Management Device, Production Management System, and Production Management Method

A production management system including a production management device for managing the production of products and a control system for controlling production resources in a production line, the production management system comprising:

• a countermeasure planning section that formulates a countermeasure plan for production resources of factory equipment in which an abnormality is detected;
• a storage section that stores line capacity information and plan information, the line capacity information being associated with the countermeasure plan and the production resources and including registered parameters indicating the production capacity of the production line before and after countermeasure implementation, the plan information indicating the production capacity of the production line that involves the production resources in a normal state;
• a capacity model creation section that creates a capacity model predicting the production capacity of the production line before and after countermeasure implementation based on the countermeasure plan through the use of the formulated countermeasure plan, the line capacity information, and the plan information;
• a coordination planning section that generates maintenance configuration information including the description of maintenance work corresponding to the countermeasure plan, the number of workers required, work time, and cost, uses the capacity model and the maintenance configuration information, and coordinately formulates a maintenance plan, including maintenance timing for performing the maintenance work and the maintenance configuration information, and a production plan change proposal for a product to be changed by the maintenance work, in such a manner as to maximize a predetermined production KPI (Key Performance Indicator) in accordance with the combination of the maintenance timing and the production plan change proposal;
• and
• a control program generation section that generates a control program for controlling each device of factory equipment involved in the production line in accordance with the production plan change proposal, and transmits the generated control program to the control system.

A production management method used by a production management device, the production management method comprising:

• a countermeasure planning step of causing the production management device to formulate a countermeasure plan for production resources of factory equipment in which an abnormality is detected;
• a storage step of causing the production management device to stores line capacity information and plan information, the line capacity information being associated with the countermeasure plan and the production resources and including registered parameters indicating the production capacity of the production line before and after countermeasure implementation, the plan information indicating the production capacity of the production line that involves the production resources in a normal state;
• and
• a capacity model creation step of causing the production management device to create a capacity model predicting the production capacity of the production line before and after countermeasure implementation based on the countermeasure plan through the use of the formulated countermeasure plan, the line capacity information, and the plan information.
