It is studied that several constructive heuristics for solving the sequence dependent setup time flowshop problem with the objective of minimizing makespan. Three priority rules imbedded in the heuristics are tested and a tie-breaking strategy is examined. The experimental results on benchmarks show that the priority rules are helpful to improve the performance, especially for the instances in which...
NEH is an effective heuristic for solving the permutation flowshop problem with the objective of makespan. It includes two phases: generate an initial sequence and then construct a solution. The initial sequence is studied and a strategy is proposed to solve job insertion ties which may arise in the construct process. The initial sequence which is generated by combining the average processing time...
