چکیده
This paper presents a new heuristic named GAPH based on a structural property for minimizing makespan in no-wait flowshop with sequence-dependent setup times. Experimental results demonstrate the superiority of the proposed approach over thhree of the best-know methods in the literature. Experimental and statistical analyses show that the new heuristic provides better solutions regarding the solution quality and computational effort.

متن کاملA Multi-objective Immune System for a New Bi-objective Permutation Flowshop Problem with Sequence-dependent Setup Times
We present a new mathematical model for a permutation flowshop scheduling problem with sequence-dependent setup times considering minimization of two objectives, namely makespan and weighted mean total earliness/tardiness. Only small-sized problems with up to 20 jobs can be solved by the proposed integer programming approach. Thus, an effective multi-objective immune system (MOIS) is ...
متن کاملA hybrid heuristic algorithm for the no-wait flowshop problem with sequence-dependent setup times
We consider the NP-hard no-wait flowshop scheduling problem with sequence-dependent setup times to minimize makespan. We propose a hybrid heuristic which combines the iterated greedy process with local search method based on a block swap operator. Experimental results show that the proposed heuristic is comparatively more effective than the existing metaheuristics.
