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. Flow-shop scheduling is a special case of job-shop scheduling where there is strict order of all operations to be performed on all jobs. Flow-shop scheduling may apply as well to production facilities as to computing designs. See more Flow-shop scheduling is an optimization problem in computer science and operations research. It is a variant of optimal job scheduling. In a general job-scheduling problem, we are given n jobs J1, J2, ..., Jn of varying … See more The sequencing problem can be stated as determining a sequence S such that one or several sequencing objectives are optimized. See more The proposed methods to solve flow-shop-scheduling problems can be classified as exact algorithm such as branch and bound and heuristic algorithm such as genetic algorithm See more There are m machines and n jobs. Each job contains exactly m operations. The i-th operation of the job must be executed on the i-th machine. No machine can perform more than one operation simultaneously. For each operation of each job, execution time is specified. See more As presented by Garey et al.
