Abstract

Abstract Flexible assembly systems (FAS) promise to be an efficient processing approach for producing small and medium-sized batches of products. One vitally important element which affects the achievement of high performance by the FAS is its scheduling/dispatching component operating within the production planning and control system (PPCS). A detailed definition of the FAS scheduling process is given and key differences between this process and the classical simple job shop scheduling process are discussed. A mathematical model is developed for the minimize makespan problem, and it is shown that the problem is NP-complete, that it is one the most difficult problems in the class of decision problems that can be solved by polynomial time nondeterministic algorithm (NP). The design of heuristic solution procedures is also discussed.
