摘要: 在允许缺货和考虑资金机会成本情况下,根据时滞变质品的基本库存模型,分别构建了信用期下供应商为领导者(SL)和零售商为领导者(RL)的Stackelberg博弈模型。通过分析SL和RL下的Stackelberg博弈模型唯一均衡解,得到两个模型中均衡解的解析表达式。最后,根据数值算例分析得出:(1)在SL供应链中信用期并不总使整个供应链协调,然而在RL供应链中信用期的协调效果较好;(2)延长信用期或增加零售价格均能刺激零售商多订货;(3)在两个模型中,零售价格均随变质时刻递增,且整条供应链达到Pareto改进;(4)SL中供应商变动信用期与RL中零售商变动价格相比,SL供应链收益更高;而当信用期和价格固定,其他参数变动时,RL供应链收益更大。

Abstract: Based on the inventory model of non-instantaneous deteriorating items, two kinds of inventory models(supplier as the leader-SL & retailer as the leader-RL), by considering shortage and cash time cost, based on Stackelberg game for non-instantaneous deteriorating items under trade credit are developed. The equilibrium solutions of the two models are obtained by analyzing the Stackelberg game model. Finally, our results of the numerical examples show: (1)Trade credit is not always an appropriate way to coordinate the whole supply chain in SL, while it is much better for the supply chain with the RL; (2)And prolonging the trade credit or improving sales price can increase the order quantity; (3)The sales price is increasing with deterioration time, and the whole chain gets the Pareto improvement in both SL and RL models; (4)Comparing supplier changes the trade credit period in SL with changing the sale price in RL, the profit of SL is much higher when changing the trade credit period in SL; however, when the trade credit period and price are fixed, the profit of RL is much higher.
