摘要
提出了一种新的求解置换flowshop调度问题的启发式算法。问题的目标是:在满足约束条件的前提下使得调度的makespan尽可能地小。定义了一种新的邻域结构。给出了跳坑策略以跳出局部最优解并且将搜索引向有希望的方向。计算了一组著名的问题实例。计算结果表明,算法的优度高于一种改进的遗传算法。
A new heuristic algorithm,which is based on local se arch framework,for solving permutation flow shop schedul-ing is presented.A n ew concept of neighborhood structure is proposed.A jumping strategy is propose d to jump from local optimal solution and guide the search in promising directi ons.This approach,in a reasonable amount of computer time ,finds the optimum solutions to a set of standard problem instances.This algorithm yields better solutions than an efficient genetic algorithm discussed in the literature.
