摘    要:研究并行批处理机的组批调度问题,考虑炉容相同、功率不同的非等同并行机的总能耗约束,考虑工件尺寸和到达时间不同,以最小化最大完工时间为目标建立混合整数规划模型。并行机组批调度问题属于NP-hard问题,采用先组批后调度的两阶段方式求解。组批阶段采用基于FFLPT和BFLPT的启发式规则,调度阶段设计带邻域搜索的粒子群-遗传混合算法对模型进行求解。以轧辊生产企业并行热处理设备为研究案例进行模型和算法验证,分析不同能耗约束下最大完工时间优化值,并比较算法的优化性能。实验结果表明:本文算法提高标准遗传算法的收敛速度,且优于2种启发式算法;能耗与最大完工时间之间存在冲突关系,通过本文的模型和算法得到能耗与最大完工时间的近似Pareto前沿面,可为企业的实际生产提供指导。

Abstract: Non-identical parallel machines with same capacity but different power were considered for batching scheduling problems. A mixed integer programming model minimizing makespan was established, with different job sizes and arrival times. As the parallel machine batching scheduling problem was NP-hard, a two-phase method, that was, first batching and then scheduling, was adopted to solve the model. At the phase of batching, two heuristic rules, FFLPT and BFLPT, were employed; and a PSO-GA hybrid algorithm with neighborhood search was designed at the phase of scheduling. The proposed model and algorithm were validated under a case study of parallel heat treatment equipment in roller manufacturing. Optimized makespans under different energy consumption constraints were analyzed, and the performance of different algorithms were compared. The results show that the proposed algorithm improves the convergent speed of standard genetic algorithm, and outperforms the other two heuristic algorithms. Meanwhile, there exists trade-offs between energy consumption and makespan. And the approximate Pareto frontier of these two indicators obtained by the proposed model and algorithm may provide guidance for real production in enterprises.
