城市物流中心车辆配送配载调度指派模型研究

Study on Two-objective Programming Model of Loading and Delivery in City Logistics Dispatching System

基于交通条件约束、客户时间窗约束以及车辆承载能力约束条件下 ,以车辆的配送路径最短、拼装货品最多为优化目标 ,研究车辆配送与配载的两目标优化调度模型组 ,该模型组可以完整描述调度过程的优化目标和约束条件 .以VB6 .0进行仿真模拟 ,结果表明该模型可以有效模拟配送中心调度系统在多种约束条件下的配送、配载调度过程 ,得到的调度指派方案是可接受的 ,而且是有效的 .

This paper proposed a group of models with two optimal objections which are to solve the loading and delivery dispatching problems under traffic conditions,time windows and vehicle capacity constraints.A simulation based on this group of models and programmed by VB6.0 is realized with a good and effective result.
