针对信息共享行为的优化需求,构建了基于Multi-Agent的信息共享行为模型,该模型由Agent特性、A-gent信念、Agent连通性和Agent行为4个模块组成.在Agent信念模块,提出了关于信念的信任值量化更新方法,将其作为信息共享行为交互的优先级排序的依据.规范了Agent发送信息、接收信息和处理信息的实验流程.通过仿真实验,得出了较为理想的信息共享行为组织模式,实现了信任阈值下的信息过滤,通过实验结果分析验证了信息共享行为模型的有效性.%In order to achieve optimal information sharing behavior,a multi- agent model is constructed,which includes four modules of agent characteristics,agent belief,agent connectivity and agent behavior. In the module of agent belief,a trust evolution algorithm of belief is put forward and is looked as a priority level standard of information sharing behavior. In the experiment flow,the agent send message flow,receive message flow and handle message flow are put forward. The simulation results show the perfect organization mode of the information sharing behavior and achieve the information filter,which are based on the proposed model,and the feasibility of the model is validated consequently.
