供应链中几种不同博弈的库存系统

一般的供货商与销售商联合库存模型均基于如下两个假定：①供货商与销售商之间是合作的；②双方信息共享。放松了上述的假定，本文建立了供货商与销售商非合作博弈的库存控制模型，分别给出了对称信息静态博弈、对称信息动态博弈以及非对称信息静态博弈下供货商与销售商的Nash均衡策略。最后通过应用实例，比较了这几种博弈下供销双方的最优策略及相应利润，为本文提供的方法进行实证研究。

Inventory Systems in Supply Chains Based on Several Different Games

In the general vendor-buyer integrated inventory models, there exists two common assumptions. Firstly, the relationship between vendor and buyer is cooperative. Secondly, vendor and buyer can share all the information. In this paper, we relax these assumptions and develop an inventory control model for vendor and buyer system by considering non-cooperative game. The Nash equilibrium policies for static game of symmetric information, dynamic game of symmetric information and static game of static game are provided, respectively. In the end, we compare the optimal policies and profits under different games through practical examples, which also illustrate the solution procedure.
