摘要:
针对供应链中时变需求的变质商品,建立了多品种的库存模型,通过该模型分别求得单独订购策略、统一定购策略和联合订购策略下的总成本函数, 经过对这些总成本函数性质的分析,提出了多种变质商品的最优订购策略.最后给出了算例.算例结果表明:当附加订购成本占订购成本的比例较大时,集聚效应明显,最优的订购策略趋于联合订购; 当附加订购成本占订购成本的比例很小时,最优的订购策略趋于统一订购; 当订购成本增大时,订购次数减少,供应链中的循环库存增加; 当库存成本或变质成本增大时,订购次数增大,供应链中的循环库存减少.
Abstract:
An inventory model of multi-deteriorating items with time-varying demand is established in supply chain. Through this model, the total cost functions under independent ordering policy, unanimous ordering policy and joint ordering policy are obtained respectively. The properties of the total cost functions are analyzed and then an optimal ordering policy of multiple productions is proposed. Finally, some numerical examples are given. The results show that aggregating effect increases with a larger proportion of additional ordering cost to ordering cost, and the joint ordering policy approaches to the optimal one; on the contrary, the unanimous ordering policy approaches to the optimal one. The number of ordering reduces and cycle inventory in supply chain increases as the ordering cost increases. When the inventory cost or deteriorating cost increases, the number of ordering increases and cycle inventory in supply chain reduces.
