Dual-sourcing procurement policy for demand-price sensitive products

在现货市场供应不确定的情况下,分析了销售商通过传统退货契约和现货市场双重渠道下的采购策略。首先分析了现货供应充足条件下销售商和供应商的最优决策,然后对现货市场供应不确定的情况进行了分析。在此基础上,通过数值方法分析了不同市场条件下销售商订购量和零售价格及其期望利润的变化情况。结果表明,现货市场的出现会使商品零售价格下降、市场需求增加,但是销售商和整个供应链的期望利润减少了;现货供应不足时的合约订购量高于现货供应充足的情况,但是零售价格保持不变,现货供应充足与否对市场需求并没有产生影响。
