Abstract:

An extended MRP II-based production management system (PMS) is presented, which improves the traditional MRP II paradigm. It does so by attaching an intelligent decision supporting system (IDSS) to the lowest level of the PMS, namely the production activity control (PAC) subsystem. The IDSS includes a simulator, that imitates real system behaviour, a knowledge-based component, that imitates expert reasoning, and a real-time database manager, that acts as the data pool and the communication gate between them. It is capable of performing off-line and on-line rescheduling, thus resulting in more realistic short-term production schedules. Analysis of the related case problem and implementation of the system are also discussed.
