中文摘要：
针对需求受价格影响和需求受价格、库存量共同影响的两种情况,考虑销售商允许缺货且缺货期间出现短缺量部分拖后,研究多个供应商、多个销售商情况下,供应商库存外包于第三方的易变质产品库存联合决策模型.对比分析两模型的结论表明,需求依赖当前销售价格和库存量情况下,考虑易变质产品库存问题更贴近实际,存在最优订货周期、最优销售价格使得供应链整体利益最大化,此时,供应链整体利润并不随着缺货率的增加而单调减小.
英文摘要：
For the two cases that the demand is influenced by the prices and the price-stocks, considering that vendors allow out of stock during the partial backlogging, under multiple vendors and multiple suppliers, deteriorating item inventory joint decision-making models are researched, and the methods are given to solve the models. The conclusion of comparing the two models shows that the demand depends on the current price-stocks more in line with the actual. There are the optimal ordering cycles and optimal sale price to maximize the interests of the whole supply chain. The whole supply chain profit can not decrease monotonously with the increase of shortage rate.
