Abstract: The paper is to analyze the problem of the evolution path of cooperation game model under SDN enterprises. And the traditional research into the cooperation game of the enterprises mostly is concentrated on two strategies between cooperative strategy and non-cooperative strategy. Different from the traditional research, the paper subdivides the non-cooperative strategy into competitive strategy and neutral strategy on the basis of the traditional research. And the supply and demand network of enterprise with multi-functional and opening characteristics is introduced into the analysis of this study. The paper also establishes a cooperation evolutionary game model of the SDN enterprises based on the theory of evolutionary game, discussing the important problem of choice of strategy of the SDN enterprises cooperation and the problem of evolution path. The results show that the choice of enterprises strategy presents unstable phenomena for a long term, such as cooperative strategy, non-cooperative strategy or both, and the direction of evolution path is closely related to the player’s payoff and influenced by model’s initial status.

Key words: SDN, cooperation strategy, competition strategy, neutral strategy, evolutionary game, evolution path

摘要： 传统企业间合作博弈问题的研究大都是基于合作策略和不合作策略两种情形展开,而与传统研究不同,本文在此基础上将企业间不合作策略细分为竞争策略和中立策略。以多功能开放型供需网企业为研究对象,运用演化博弈理论分析方法,通过构建供需网企业合作演化博弈模型,进而分析供需网企业合作过程中策略的选择以及博弈演化路径问题。研究结果表明:在长期的演化博弈过程中,企业策略的选择情形出现不稳定现象,即出现完全合作、完全不合作或者一方合作而另一方选择不合作策略的多种状态,其演化路径最终稳定于何种情形与模型的支付矩阵和初始参数设置有关。
