摘要:

研究了多目标柔性作业车间调度问题,构建了以制造工期、加工成本及交货期为目标函数的柔性作业车间多目标调度模型,应用改进的强度Pareto进化算法(SPEA)进行求解。在该算法中,引入模糊C-均值聚类(FCM)加快外部种群的聚类过程。采用约束Pareto支配和双层编码策略,一次运行就能够求得Pareto最优解集,并利用模糊集合理论的方法得到Pareto解的优先选择序列和选出一个最优解。最后,将该方法应用于某机械公司车间调度中,验证了该方法的有效性和适应性。

Abstract:

To solve FJSP, a multi-objective FJSP optimization model was set up, concerned with time, cost and delivery satisfaction. The optimal solutions were obtained by using improved SPEA. The SPEA was improved by introducing the fuzzy C-means clustering algorithm to accelerate the clustering procedure within the external population. With the constraint Pareto domination concept and the two-level representation schema, a Pareto optimal set could be achieved in a single run. Then the preference sequence of Pareto solutions was achieved and a solution was extracted as the best compromise one based on set theory. The feasibility and validity of the proposed algorithm have been proved by the results in a workshop scheduling.  flexible job-shop
