Scheduling of Single-Item Freight Transportation and Inventory

摘要: 提出了一类货物需求量仅随时间发生变化、成本函数为凸函数的单货物品种运输和存储联合调度问题. 为了最大限度减少运输和存储成本,必须制定出最优的运输和存储调度方案.为此,设计了一种寻求最优调度方 案的网络图优化算法.最后,通过算例对该算法进行验证,结果说明该算法是可行的.Abstract: The single-item freight transportation and inventory scheduling problem with a time- varying demand and a convex cost function was investigated. To minimize farthest the total cost of transportation and inventory, the optimal transportation and inventory scheduling scheme must be arranged. For this reason, a graph algorithm to optimize transportation and inventory scheduling schemes was proposed. At last, the proposed algorithm was illustrated using an example. The result shows that the algorithm is feasible.
