Production management system.

摘要

A production management system for optimizing the operation of each station in a production line by the use of an expert system including a knowledge data base for generating an optimum production command for each of the stations. The expert system is equipped with a simulator for simulating and evaluating a future operating condition of the production line for each possible course of action and obtaining optimum production command data under each given circumstance. Thus, it can carry out a highly efficient and adaptive production management under any circumstance because the simulator can offer an optimum production command data even when the knowledge data base is unable to arrive at an optimum solution. Therefore, the knowledge data of the expert system is not required to cover every possible circumstance, and is therefore not required to have a large storage capacity to ensure the adaptability of the system.
