铁路特种箱空箱调度模型及求解算法

Dispatching Model and Solution Algorithm of Empty Railway Special Containers

从4个方面分析铁路特种集装箱空箱调度进行优化设计的必要性,在特种箱资源供不应求的情况下,考虑运输能力、定点维修和时间限制等约束条件,构建特种箱空箱调度模型,运用遗传算法求解模型,并通过算例验证该模型的可行性,为实现物流网络内总体效益的最大化、减少排空费用的支出提供参考。

This paper analyzes the necessity of implementing optimization design for empty special con-tainers from 4 aspects,under the condition of special container resource supply falls short of demand,considers the restriction condition of transport capacity,appointed maintenance and time limit,establishesdispatching model of empty special containers,applies the genetic algorithm solution model and validatesthe model feasibility through examples,all of which could realizes maximum general benefit of logistic net-work and provides reference to reduce the payout of arranging empty containers.
