不同信息结构下的供应商和生产商Newsboy问题研究

Newsboy problem for vendor-manufacturer with different market information

研究由两个零部件供应商和一个生产商构成的两阶段供应链的Newsboy模型。零部件供应商关于需求具有相同的信息,研究生产商相对零部件供应商关于市场需求信息是否具有信息优势、以及供应商之间是否合作对博弈结果和整个供应链效率的影响。无论信息对称与否,供应商之间合作对供应商和生产商都有利;若供应商和生产商不能一体化决策,生产商保持信息优势对生产商和整个供应链效率有利,而对零部件供应商不利。最后给出算例,说明和验证所建模型的正确性。

A Newsboy model consisting of a final product and multiple parts is presented. In the model, the vendors have the same market information, but the manufacturer may have better market information than the vendors. On the other hand, the vendors may set a price respectively or coordinate and set a unitied price of parts. The focus is on assessing the value of market information and the coordination between vendors.
