For the past three decades or so the flexible flow shop (FFS) scheduling problem has
attracted many researchers. Numerous research articles have been published on this topic …

The Flexible flow shop (FFS) is defined as a multi-stage flow shops with multiple parallel
machines. FFS scheduling problem is a complex combinatorial problem which has been …

In simple flow shop problems, each machine operation center includes just one machine. If
at least one machine center includes more than one machine, the scheduling problem …

Flexible flow shop (or a hybrid flow shop) scheduling problem is an extension of classical
flow shop scheduling problem. In a simple flow shop configuration, a job having …

The classical flexible flow shop scheduling problem (FFSP) only considers machine
flexibility. Thus far, the relevant literature has not studied FFSPs with worker flexibility, which …

In this paper, an efficient algorithm is presented to solve flexible flow-shop problems using
fuzzy approach. The goal is to minimize the total job tardiness. We assume parallel …

This paper considers a flexible flow shop scheduling problem, where at least one production
stage is made up of unrelated parallel machines. Moreover, sequence-and machine …

Flexible flow shop scheduling problems are NP-hard and tend to become more complex
when stochastic uncertainties are taken into consideration. Although some methods have …

In textile industries, production facilities are established as multi-stage production flow shop
facilities, where a production stage may be made up of parallel machines. This known as a …

In this research, flexible flow shop scheduling with unrelated parallel machines at each
stage are considered. The number of stages and machines vary at each stage and each …
