摘要:

将一种改进的狼群算法用于解决柔性作业车间多目标调度优化的难题。以工件的最大完工时间和机器能耗为优化目标建立了多目标柔性作业车间调度模型;针对传统狼群算法容易陷入局部最优的缺点提出了一种改进的狼群算法,通过对狼群算法智能行为的改进,从工序和机器2个层面设计个体编码,引入POX (precedence operation crossover)交叉操作,保证解的合法性,提高算法的全局搜索能力;通过对2个车间实例的对比实验来验证改进狼群算法的有效性。实验结果表明,提出的改进狼群算法不仅具有良好的全局搜索能力,寻优能力较其他算法也有所提升,能够为制造业提高生产效率提供新的解决思路。

Abstract:

An improved wolf pack algorithm is proposed for solving multi-objective scheduling optimization for flexible job shop problems. A multi-objective flexible job shop scheduling model is developed with the maximum completion time of the workpiece and the energy consumption of the machine as the optimization goals. An improved wolf pack algorithm is proposed for solving the shortcomings that traditional wolf pack algorithm is easy to fall into the local optimization. Through improving the intelligent behavior of the wolf pack algorithm, individual codes are designed from the two levels of job's process and machine, and POX(precedence operation crossover) cross operation is introduced to ensure the legality of the solution and improve the search ability of the algorithm. The effectiveness of the improved wolf pack algorithm is verified through comparative experiments on two workshop examples. Experimental results show, the improved wolf pack algorithm not only has good global search ability, but also has an improved optimization ability compared with other algorithms. It can provide new solutions for the manufacturing industry to improve production efficiency.

Key words: improved wolf pack algorithm, job shop scheduling, energy consuming, multi-objective optimization
