Efficient Metaheuristics for Multi-stage No-Wait Flexible Flowshop Scheduling Problem
The issue of sequencing and scheduling has received considerable critical attention in many fields since the early 1950s. In this research, we studied an important production scheduling system, which generally called flexible (or hybrid) flowshop scheduling problem (FFSP or HFSP). We studied this production system with an important restriction called the no-wait. The objective was to optimize t...
متن کاملA Two-Stage Hybrid Flowshop Scheduling Problem with Serial Batching
In this paper the problem of serial batch scheduling in a two-stage hybrid flow shop environment with minimizing Makesapn is studied. In serial batching it is assumed that jobs in a batch are processed serially, and their completion time is defined to be equal to the finishing time of the last job in the batch. The analysis and implementation of the prohibited transference of jobs among the mac...
متن کاملApproximability of two-machine no-wait flowshop scheduling with availability constraints
We consider in this paper the two-machine no-wait flowshop scheduling problem in which each machine may have an unavailable interval. We present a polynomial time approximation scheme for the problem when the unavailable interval is imposed on only one machine, or the unavailable intervals on the two machines overlap.
متن کامل3/2-approximation for Two-machine No-wait Flowshop Scheduling with Availability Constraints
We consider in this paper the two-machine no-wait flowshop problem in which each machine may have an unavailable interval. We present 3 2 -approximation algorithms for the problem when the unavailable interval is imposed on only one machine, or the unavailable intervals on the two machines overlap. These algorithms improve on existing results.
متن کاملNo-wait flexible flowshop scheduling with no-idle machines
This paper considers a two-stage flexible flowshop scheduling problem with no waiting time between two sequential operations of a job and no idle time between two consecutive processed jobs on machines of the second stage. We show its complexity and present a heuristic algorithm with asymptotically tight error bounds. © 2004 Elsevier B.V. All rights reserved.
