摘要

针对多目标应急物资配送中车辆路径优化问题，提出了基于改进智能水滴算法的多目标应急物资路径优化方案。主要包括以下四个阶段：a）构建基于Holling-Ⅱ函数的疾病扩散模型；b）各疫区对药品的需求预测；c）构建多目标应急物流配送模型；d）改进的智能水滴算法求解多目标应急物资优化问题。研究结果表明，所建立的模型与算法有效可行，可为应急管理相关问题提供决策参考。%For the multi-objective vehicle routing problem in emergency logistics distribution,this paper proposed an improved intelligent water drops algorithm for multi-objective routing programming scheduling of emergency materials.The main contents consist of four steps:a)constructed the disease spreading model in multiple areas based on Holling-Ⅱfunction,b)data fusion to forecast the relief demand in multiple areas,c)built the multi-objective mathematical model with the minimum emergency logistics distribution time and cost,d)designed an improved intelligent water drops algorithm for multi-objective emergency materials distribution path optimization.The results show that the established model and algorithm are effective and feasible, which can provide references for decision makers of emergency logistics management.
