基于优先级的物流园区共同配送车辆调度优化研究

Research on Vehicle Scheduling Optimization of Joint Distribution in Logistics Park based on Priority

为高效、快速地保证配送任务的完成,实现配送成本最优,在分析物流园区共同配送过程中产生的各种成本的基础上,构建基于优先级的车辆调度优化模型。借鉴交通流分配的思想,引入虚拟距离,提出模型的求解思路和算法。最后,在实际算例中,通过运行Lingo,得出最优车辆调度方案。

In order to deliver efficiently and rapidly with minimum cost,various costs generated during the joint distribution of Logistics Park are analyzed and the optimization model on vehicle scheduling is set up according to priority. The solution and algorithm of the model are put forward based on the distribution theory of traffic flow and the virtual distance. They are demonstrated in Lingo environment and the optimum vehicle scheduling is obtained.
