Web1 Introduction. The flexible flow shop scheduling problem (FFSP) is a generalization of the classical flow shop problem (FSP), wherein all products follow the same flow processing line but all of them may not visit all processing stages. When some stage on the line performs an assembly operation, the problem is known as FFSP-A. WebThis paper discusses the flow shop scheduling problem to minimize the makespan with release dates.
