Fuzzy Logic in Flexible Manufacturing System for Production Scheduling

Abstract

Fuzzy logic, although a mathematical technique, defines its behavioral framework through a compact linguistic rule base. It has the ability to concurrently consider multiple criteria and to model human experience in the form of simple rules. Furthermore, the advantage of the fuzzy logic system approach is that it incorporates both numerical and linguistic variables. By applying a fuzzy logic to overcome the dynamic scheduling problems in an FMS environment. The fuzzy based scheduling is designed to solve the problem of selecting the best job assignment for a given job which is the sub-problem of scheduling in a Flexible manufacturing system (FMS).
