基于多报童模型合作的窜货问题研究

Cooperation/Transshipment Discussion Based on Multiple Newsboy Model

研究由n个零售商组成的窜货联盟合作问题,假设每个零售商面临的市场需求都是报童型问题,即他们销售有一定期限(产品生命周期短,如时尚消费品等)的商品·在多报童模型基础上,通过定义一个存在n个零售商的合作博弈(称为报童问题博弈),并研究一般的报童博弈的性质来探讨这类联盟合作的作用及意义·研究表明,一般的报童问题博弈都有一个非空的核心,且合作形成的联盟可以使各零售商获得更多的期望利润·

Discusses the cooperation in a transshipment alliance consisting of n retailers. Assuming that each of them is facing to a market demand that is attributed to the multiple newsboy problem, i.e., the commodities that are wanted to he sold out are all of perishable goods with short shelf-life, the alliance organized by those retailers can make more profits they jointly expect through negotiatory orders and cooperative transshipments. Based on the multiple newsboy model and analyzing the case of n retailers who are co-ordinatlng their efforts in their joint orders and associated reallocation, a cooperative game is defined as ＂general newsboy game＂ of which the features and their effects on the corresponding cooperative alliance are discuased. A conclusion is thus drawn that all the general newsboy games have a nonempty core and an alliance based on cooperation enables each and every retailer to make more profits expected.
