以包含两个销售商的库存系统为例,构建了一个描述库存共享应对突发事件的非合作博弈模型,证明了其纳什均衡解是唯一存在的。研究结果显示库存共享策略总有可能使得销售商的期望利润得以改进。另外,比较静态分析反映了转载价格和转载成本显著影响库存共享销售商的最优订货量和最优期望利润。最后,提出了一个简单的求解模型纳什均衡解的启发式算法。
Consider a two-retailer inventory system, a Non-cooperative game model is established to describe inventory pooling policy under disruption risk. It is proved that there exists a unique Nash equilibrium solution to the model. Model analyses show that lateral transshipments always possibly improve retailer's optimal expected profits under demand disruptions. Moreover, comparative static results reflect transshipment price and transshipment cost are two important parameters for optimal order volumes and optimal expected profits. At last, a heuristic algorithm is designed to solving the model's Nash equilibrium.
