Constraint production management using Fuzzy Control

The functions of short-time planning and control of orders on the factory's shop floor can be supported by Production Management Systems. A scheduling system capable of reflecting the planning staff's experience has been implemented. Due to the complexity of the scheduling problem and the typical lack of precision in shop expert's planning strategy descriptions a system was designed based on Fuzzy Logic. The article presents concepts, theory and implementation of a Fuzzy Logic scheduling system for an aluminium foundry and mill.
