A flexible flow shop problem can be considered as a generalization of a pure flow shop problem in which the jobs have to go through the stages in the same order. We consider a flexible flow shop problem with unrelated machines and setup times, where the processing times depend on the chosen machine and setup times are sequence-dependent. While for classical problems the processing times for eac...

although several papers have studied no-idle scheduling problems, they all focus on flow shops, assuming one processor at each working stage. but, companies commonly extend to hybrid flow shops by duplicating machines in parallel in stages. this paper considers the problem of scheduling no-idle hybrid flow shops. a mixed integer linear programming model is first developed to mathematically form...

this paper presented a mixed integer programming for integrated scheduling and process planning. the presented process plan included some orders with precedence relations similar to multiple traveling salesman problem (mtsp), which was categorized as an np-hard problem. these types of problems are also called advanced planning because of simultaneously determining the appropriate sequence and m...

In the current paper, we study the concept of dynamic scheduling in flexible flow Shop with limited carrier under stochastic machine breakdowns and processing time. In most flexible flow shop scheduling methods reported in the literature consider a determinist environment, where all data of the problem are known in advance. Most of these works focused on the development of methods to produce a ...
