An Evaluation of Flow Shop Sequencing Heuristics

WebAbstract. This paper is an attempt to study general flow shop scheduling problem in which processing time of jobs is associated with probabilities under no-idle constraint. The objective of this paper is to develop a heuristic algorithm to flowshop scheduling so that no machine remains idle during working for any given sequence of jobs. The proposed … Webof idle time in the schedule can be advantageous. See [6] for a literature review about scheduling with inserted idle time. The problem parameters for all the formulations studied in the rest of this work are (a) n: the number of jobs, (b) m: the number of machines, (c) p ik: the processing time of job i on machine k, and (d) d i: the due date ... WebIn this study, a general variable neighborhood search (GVNS) is presented to solve no-idle permutation flowshop scheduling problem (NIPFS), where idle times are not allowed on machines.
