摘要
主要考虑一个三级物流系统的运送策略优化问题,系统由多个供货商、多个客户和一个中央仓库组成.假定两级库存均采用周期补货策略,每个客户处的产品需求为确定性需求.假设给定一套可行频率的情况下,选择使整个系统总的长期平均成本最小化的仓库的补货策略和仓库到各客户的配送策略.根据两个支配性质构造了一个列举优化算法,计算试验讨论了该算法的有效性.
This paper considers a three-echelon logistics system,which consists of multiple suppliers,a central warehouse（CW） and multiple customers.We assume that the CW and customers perform periodic replenishment strategies.We also assume that each customer faces a deterministic demand rate for any of products.With given a set of feasible frequencies our objective is to find the optimal replenishment strategy of the CW and the optimal shipping strategy of each customer,which minimizes the long-run average costs of the system. In this paper we derive two dominance rules for the problem solutions.The numerical experiment shows that the enumeration-followed-by-optimization algorithms is efficient.
