摘 要: 在需求不确定的情况下,构建了3个阶段中两零售商利用契约机制进行竞争的模型.通过模型求解,得出各阶段中两零售商各自的最优订货量及契约参数.最后,通过数值例子分析了模型的可行性及解的有效性,并得出当单一零售商采用一种契约机制时,两零售商的整体利润达到最大,实现了优化协调;当两零售商均采用契约机制时,整体利润受损,利润总和达到最小,整体利润的优化协调作用失效. In the uncertain market, three situations are discussed, solving the model, the optimal order quantity and contract parameters can be obtained. Furthermore, numerical examples and sensitivity are presented to illustrate the results of the proposed model and draw managerial insights. Only one retailer offering the contract, the whole profit is maximized. However, when both of the retails provide the contract to attract the customers, the whole profit decline.
