An evolutionary model for Supply Chain Partnerships system based evolutionary game

Supply chain partnerships (SCP) system is composed of independent enterprises with individual preferences. And the enterprise of SCP is bounded rationality and it presents myopia phenomenon. In channel behavior is much inefficiency and it will lead to poor channel performance. The aim of this paper is focused on obtaining the intrinsic evolutionary mechanism of the SCP system. Therefore, the profit functions of the enterprises in SCP system are presented. And the evolutionary stable model of SCP system cooperation preference degree had been founded. Farther, evolutionary stable strategy (ESS) and replicator dynamics applied to analyze the evolutionary stability trend by taking the penalty mechanisms. The conclusions illuminated the homogeneous enterprises and homogeneous enterprises had different evolutionary trend in SCP system, the penalty costs was the crucial factor on the process of SCP evolutionary.
