摘　　要：大规模突发事件发生后,如何合理高效进行应急物资的选址-调度是亟待研究的重要课题。本文针对不确定突发灾害情况,构建最大化公平性和最大化综合满意度模型。首先利用评价指标数据去模糊化求出紧迫度系数,构建基于紧迫度的公平模型;其次,考虑灾民心理恐慌因素及政府满意度构建综合满意度模型;最后,采用改进NSGA-Ⅱ算法求解问题。设计基于本文选址-调度的两阶段编码解码方案,使用自适应交叉概率和基于种群熵的变异概率公式,并设计相应交叉、变异操作,引入算子进行邻域搜索。在经典测试函数验证本文改进NSGA-Ⅱ算法有效性的基础上,通过实际案例分析表明,改进NSGA-Ⅱ算法能有效求解多目标选址-调度问题,需求紧迫度优化后在平衡公平性和满意度方面结果更优。How to reasonably and efficiently select and dispatch emergency supplies after large-scale emergencies is an important issue that urgently needs to be studied.A model is built to maximize fairness and comprehensive satisfaction in response to uncertain sudden disaster situations.Firstly,the evaluation index data are used to de-fuzzify to find out the urgency coefficient and construct the equity model based on urgency;Secondly,considering the psychological panic factors of disaster victims and government satisfaction,a comprehensive satisfaction model is constructed;Finally,the improved NSGA-Ⅱalgorithm is used to solve the problem.This article designs a two-stage encoding and decoding scheme based on location scheduling,using adaptive crossover probability and mutation probability formulas based on population entropy,and designs corresponding crossover and mutation operations,introducing operators for neighborhood search.On the basis of verifying the effectiveness of the improved NSGA-Ⅱalgorithm in this paper through classic testing functions,practical case analysis shows that the improved NSGA-Ⅱalgorithm can effectively solve multi-objective location scheduling problems,and the results of optimizing demand urgency are better in balancing fairness and satisfaction.
