摘要
针对考虑能量消耗的绿色置换流水车间调度问题,以最大完工时间和总能量消耗为优化目标,提出一种混合分解多目标进化算法(HMOEA/D).首先,为了保持初始种群的多样性,使用一种混合初始化策略产生高质量初始种群;其次,采用禁忌搜索策略作为局部搜索算子,强化算法跳出局部最优能力;最后,提出节能策略,以进一步优化总能量消耗目标.通过对标准测试集进行仿真实验并与代表性算法进行比较,验证所提出算法的优越性.
Abstract
For the green permutation flow-shop scheduling problem(GPFSP)with energy consumption,a hybrid multi-objective evolutionary algorithm based on decomposition(HMOEA/D)is proposed,which aims at optimizing both of the makespan and total energy consumption.Firstly,in order to maintain the diversity of the initial population,a hybrid initialization strategy is used to initialize the population.Then,the tabu search strategy is used as local search operator to make the population jump out of local optima.Finally,an energy-saving strategy is proposed to further optimize the total energy consumption objective.Through the simulation of the standard benchmarks,and compared with the representative algorithm,the experimental results show that the proposed algorithm achieves better performance.
