供应商之间基于声誉模型的合作博弈分析

供应链上同级供应商之间因其合作竞争关系,经常需面对策略应对与选择的难题。文章通过引入声誉模型,假定供应商为理性的不再是共同认知,分阶段讨论是否存在一个非理性概率p使其不受阶段T的影响,始终选择合作。在归纳计算后发现,在合作博弈次数T3的前提下,当供应商的信誉度p≥4/7时,他将总是选择合作;反之当p4/7时,其背叛行为则有可能出现。因此只需根据合作供应商以往的信誉是否低于p=4/7这一临界点,即可知选择何种博弈策略最为有利。

Cooperative Game Analysis Between Suppliers Based on the Reputation Model

Because of the co-opetition relations hips among suppliers at the same level in the supply chain. They often need to face the problem of strategy selection. By introducing a reputation model in this paper, that supplier are rational is no longer common, discussing in stages, whether there is a irrational probability p make it be not affected by phase of T, and always choose cooperation. After computation induction, on the premise of the number T〉3 of cooperative game,when the supplier credibility p≥4/7, the will always choose cooper-ation; On the contrary, when p〈4/7, the treachery may be happen. Therefore it just reference whether the credibility of suppliers is below the critical point of p=4/7, could know which kind of strategy is the most favorable.
