摘　　要：基于偏好的多目标优化算法能够定向搜索符合决策者需求的Pareto解集,是多目标优化算法与工程实际联系最为紧密的方法之一。为准确地将决策者偏好需求反映到最终Pareto解集,提出一种偏好映射点动态更新策略,通过动态更新偏好映射点来降低算法对初始参考点位置的依赖。为实现输出Pareto解数目可调可控,引入偏好解集过滤器,使得算法能够得到解集数目符合决策者要求、分布均匀的Pareto解。最后,利用所提算法求解ZDT系列测试函数和浙北区域直流偏磁抑制装置优化配置问题。结果表明,所提算法能有效收敛至决策者偏好对应的Pareto解集,可以为直流偏磁抑制装置优化配置工程实际问题提供符合决策者需求的优秀候选方案。The preference-based multi-objective optimization algorithm can search for Pareto solution sets that meet the needs of decision makers,and is one of the most closely related methods between multi-objective optimization algorithms and engineering practice.In order to accurately reflect the preference needs of decision makers to the final Pareto solution set,a dynamic update strategy of preference mapping points is proposed,which can reduce the dependence of the algorithm on the position of the initial preference point by dynamically updating the preference mapping points.In order to realize the adjustable and controllable number of output Pareto solutions,a preference solution set filter is introduced to enable the algorithm to obtain Pareto solutions with a uniform distribution.The proposed algorithm is used to solve the ZDT testsets and DC bias optimal configuration in North Zhejiang area.The results show that the proposed algorithm can effectively converge to the Pareto solution set corresponding to the preference of decision makers,and can provide excellent candidate solutions that meet the needs of decision makers for the actual problems of optimal configuration of DC bias suppression devices.
