研究了二级直运供应链通过共同补给期协调库存的策略问题。在该供应链中,单一的供应商向面临随机需求的多个零售商提供单一产品。在提出的库存协调策略下,当零售商接受供应商提供的共同补给期时,供应商则提供给零售商一定的价格折扣。最后,通过数值仿真分析,验证了该策略可以降低供应商的成本,而零售商成本的增加则可以通过价格折扣来补偿,从而显著地降低了供应链的总成本。
A policy of coordinating inventory by Common Replenishment Epoch (CRE) for a kind of lot-to-lot supply chain was studied and analyzed. In this supply chain, single supplier provided single product to multi-retailers with stochastic demand. Under the proposed policy of coordinating inventory, when the retailers accepted CRE provided by supplier, the supplier offered retailers a price discount, Retailers could accept or refuse the policy of coordination, which meant that the price discount to the retailers was selective. Finally, a numerical study and simulation analysis was conducted. Simulation result confirmed that the policy could reduce the cost of supplier, and the increased cost of retailer could be compensated by price discount so as to reduce the total cost of supply chain.
