Variable Weight Method for Multi-objective Optimization of Freight Flow Allocation in Logistics Network

摘要

摘要: 为克服多目标物流网络货流分配问题中加权求和求解方法的主观片面性,在具有固定拓扑结构的物流网络的基础上,建立了以运输线路和物流节点能力为约束条件、以物流成本最小、最长单程运送时间最短以及网络使用率最高为优化目标的多目标物流网络货流分配优化模型,并提出了基于变权的模型求解方法:首先,构建了物流网络变权模型,通过状态变权函数实现变权操作,使变权结果不仅反映了决策者的主观偏好,而且与客观的目标状态值相关联;其次,根据物流网络变权模型计算基于优化目标变权综合的路径状态值,并进行最优路径选择和货流分配；最后，通过算例对优化模型及求解方法进行了验证.

Abstract: To overcome the shortness of traditional weighted-sum method (WSM) for multi-objective optimization of freight flow allocation in logistics network, a variable weight method was proposed, in which the weights of optimization objectives are variable. The variable weights are determined by preset weights and state values of logistics network elements including the nodes, lines and paths. Those state values are obtained with a WSM based on the attribute values of the elements. The proposed method was applied to an optimization example of logistics network where the restraints are the capacities of transport lines and logistics nodes, and the objectives are the minimum logistics cost, shortest one-way delivery time, and the maximum utilization ratio of the logistics network.
