Abstract: According to the characteristic that customer demand less
Quantity and more times, an optimal model which consolidated stock replenishment and delivery scheduling was modeled to compute upper-level inventory Q and delivery cycle T，as well as to minimize long-run average cost in VMI-systems. Solution of this model also was researched. As example show, it is appropriate to take delivery Consolidation strategy when and AD are large, whereas, direct delivery strategy is appropriate.

Key words: optimal modeling, stock replenishment, delivery consolidation

摘要： 针对客户需求小批量、多批次配送的特点，建立了供应商管理库存(VMI)模式下供应商库存补充和配送整合策略优化模型，以计算整合策略中最高库存量Q和配送整合周期T,达到最小化长期平均期望总成本的目的，并探讨了其计算方法.算例表明，当参数 和AD较大时，适合采用配送整合策略，反之，适合用直接递送策略.
