A variable weight method for multi-objective optimization of freight flow allocation in logistics networks. (Chinese. English summary) Zbl 1265.90063

Summary: In order to overcome the shortness of traditional weighted-sum method (WSM) for multi-objective optimization of freight flow allocation in logistics networks, a variable weight method is 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 is applied to an optimization example of a 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.
