摘　　要：在知识服务网络中,知识供应方和知识需求方在传递知识的过程中进行着重复博弈,并根据收益矩阵选择有利策略逐渐模仿,最终采用某个策略达到了演化稳定均衡状态.首先,根据演化博弈理论,建立了知识服务网络的复制动态演化博弈模型.然后,采用多智能体建模仿真方法及Netlogo仿真平台对所建模型进行仿真分析.最后,通过仿真分析得到在不同的初始情况下,知识主体最终的演化稳定策略与各主体中采取合作策略的初始比例和鞍点的大小关系有关,验证了所建立模型的正确性.The suppliers and demanders of knowledge process a repeated game in a knowledge service network,they imitate the favorable strategies according to the gains matrix,finally to adopt a strategy to achieve a stable equilibrium state of evolution.Based on the evolutionary game,the paper builds a replicator dynamics evolutionary game model of knowledge service network.Then the model is simulated on the Multi-Agent System method and Netlogo platform.The simulation reveals the stable strategies of suppliers and demanders in different initial case relate to the rate of the agents who took the cooperative strategy in the beginning and the value of saddle point,demonstrating the correctness of the model.
