As market competition intensifies, there is a demand for modular production systems that can handle multiproduct variable quantity production. The problem of determining an appropriate facility layout and process schedule according to fluctuating orders tends to generate combinatorial explosion because mutual dependence of both design variables causes increase of solution space. In this paper, we apply ZDD, which is the data structure that can efficiently express combination sets, to the simultaneous planning method of facility layout and process schedule. We show a method of constructing solution space satisfying constraints according to fluctuating orders while suppressing combinatorial explosion.
