Transshipment Nodes Location of Relief Materials Based on Improved GA
摘要
Abstract
This paper studies a multi-objective location problem of transshipment nodes in joint allocation and transportation of mass relief materials. Transportation costs, operating variable costs of transshipment nodes and travel time are considered, and a nonlinear multi-objective mixed integer programming model for the transshipment nodes location of relief materials is proposed. To solve the model effectively, a matrix-based encoding GA is proposed, in which the cost matrix of the optimization-oriented benchmarking information is used to enhance local search ability of genetic mutation operator and improve global convergence speed. A numerical example verifies the effectiveness of the model and algorithm.关键词
