铁路物流中心多目标分层选址优化模型及算法
Multi-obj ective model and algorithm for optimizing the location of railway logistics centers based on different grades
摘要
Abstract
To construct and develop railway logistics centers (RLCs)is a foundational proj ect to develop modern logistics for China Railway Corporation.Reasonable location of RLCs is impor-tant to improve Railway Corporation's freight and logistics market competitiveness compared with other modes of transportation.This paper mainly focuses on optimizing the location of RLCs based on different grades,which takes all the railway freight yards as research obj ects.Based on the evaluation of railway freight yard with the method of improved DEA,a 0-1 mixed integer programming model about the location of RLC is raised in this paper,of which the obj ective func-tions are the maximum utilization of railway freight resources and minimum of construction costs. Also genetic algorithm(GA)is designed to solve this model.Finally,a location plan of RLCs in China is proposed,which contains 45 first-grade RLCs,256 second-grade RLCs,509 third-grade RLCs,based on 2500 railway freight yards.This result can fully prove that the model and solu-tion algorithm are effective.Also this location plan can provide reference for RLCs'construction to the decision-makers.关键词
