【摘要】 把经典的报童模型扩展到了两产品情况,其中一种产品有多余库存时可以替代另外一种缺货的产品进行销售,探讨了可替代产品在由一个供应商和一个销售商组成的二级供应链中的作月。以二级供应链系统为背景, 分别提出了采取替代策略和不采取替代策略两种情况下的Stackelberg博弈模型,给出了博弈的Nash均衡解,并分析了这两种情况下供应商的批发价和销售商的订货量随着两种产品的单位销售成本取值不同时的变化。数值分析表明当采取替代策略时,供应商的收益增加,销售商的收益减少,最终供应链的整体收益水平提高了。更多还原

【Abstract】 The impact of product substitution on the two-level supply chain containing a supplier and a retailer is studied in this paper. To perform this analysis, the basic news-vender model is extended to include the possibility that a product with surplus inventory can be used as a substitution for that out of stock products. Without loss of generality, we study the two-product case. In this paper, two kinds of Stackelberg game models are developed and analyzed. One kind of model uses the substitution policy, and the other not. In these two kinds of models, the Nash equilibrium solution is derived , and the changes of trade price and order quantity are studied as each product’ unit selling cost changes. Numerical analysis is conducted and the results show that when using the substitution policy, the supplier’ s profit is increased, the retailer’s profit is reduced, but generally the profit of whole supply chain is improved.更多还原
