摘　　要： 针对由单个供应商和多个零售商组成的两级供应链分配系统,研究了一体化的库存路径问题。为了节省整个供应链的费用,重新设计了对零售商的区域分割算法。在此基础上,确定了出零售商订货周期与供应商订货周期的大小关系,通过引入周期比例向量,设计了一个全新的整数倍时间策略,给出了详细的理论分析,证明该策略是最优的整数倍时间策略。数字实验结果表明,该策略比其他策略具有明显优越性。 For a two-echelon supply chain system consisting of single-supplier and multi-retailers, the inventory routing problem of centralized supply chains is considered. To reduce the cost of the whole chain, a region partition algorithm for the retailers is redesigned. Based on this, the relationship of the replenishment in- terval between the retailers and the suppliers is determined. By using interval ratio vector, a new integer ratio policy is designed. Through a particular theoretical analysis, it is proved that this strategy is the optimal one. Numerical experiment results show that this strategy is evidently better than others.
