基于多商品流模型的铁路网车流分配和径路优化模型
Car Flow Assignment and Routing Optimization Model of Railway Network Based on Multi-Commodity Flow Model
摘要
Abstract
By analyzing the drawbacks of node-arc and arc-route car flow assignment model, improvements were made on the following two aspects. One was to define a 0-1 decision variable which could make the optimization results reflect car flow routing. The other was to differentiate the car flows according to their volume to make the optimization results accord with the characteristics of the actual car flow organization.Based on multi-commodity flow model, the car flow assignment and routing optimization model of railway network was built, which subjected to each car flow moving on one route only, car flow with big volume,the capacity of lines and stations. The model could be solved by software Lingo 8. 0. Taking the simplified local railway network in the Northeast China for example, the car flow was assigned and the routing was optimized for railway network according to the proposed model by adopting the simulated OD car flow.Results show that more ideal car flow assignment and routing plan can be obtained by the proposed model,which has verified the rationality and the validity of the proposed model.关键词
