模糊信息背景下突发公共事件应急物资分配研究

Research on Emergency Materials Allocation for Public Emergencies Under the Background of Fuzzy Information

文中研究了突发公共事件模糊信息背景下的应急物流资源配置问题,综合考虑了各需求点的物资需求和分配优先级等不确定因素,以便将应急物资快速合理地分配给各需求点。以各需求点分配优先级、应急资源配置总时间、总成本、物资未满足率的最小乘积之和为目标,综合考虑应急物资各供应点、各配送中心和各需求点三级配置网络,构建应急物流资源配置确定性模型,并设计了NSGA-Ⅱ算法进行模型求解。最后,通过算例验证了该模型的可行性和有效性,优化了模糊背景下重大突发事件应急资源优化配置策略。

This paper studies the problem of emergency logistics resource allocation under the background of fuzzy information of public emergencies,and comprehensively considers the uncertain factors such as material demand and allocation priority of each demand point,and quickly and reasonably allocates emergency materials to each demand point.With the goal of the minimum product sum of the allocation priority of each demand point,the total time of emergency resource allocation,the total cost,and the unmet rate of materials,and comprehensively considering the three-level allocation network of each supply point,each distribution center,and each demand point of emergency materials,the deterministic model of emergency logistics resource allocation is constructed,and the NSGA-ⅱalgorithm is designed to solve the model.Finally,the feasibility and effectiveness of the model are verified by an example,and the optimal allocation strategy of emergency resources for major emergencies under the fuzzy background is optimized.
