A fuzzy control system has been developed to solve problems which are difficult or impossible to control with a proportional integral differential approach. According to system constraints, the fuzzy controller changes the importance of the rules and offers suitable variable values. The fuzzy controller testbed consists of simulator code to simulate the process dynamics of a production and distribution system and the fuzzy controller itself. The results of our tests confirm that this approach successfully reflects the experience gained from skilled manual operations. The simulation and control software was developed in APL2/2 running under OS/2. Several features of this product, especially multitasking, the ability to run AP124 and AP207 windows concurrently, and the ability to run concurrent APL2 sessions and interchange data among them were used extensively in the simulation process.
