摘　　要：对物联网环境下多智能体系统灵敏度进行分析,能够提高系统在物联网中的应用效果。针对当前物联网环境下多智能体系统灵敏度分析方法存在的分析过程复杂,对计算机网速影响较大问题,提出一种基于加权无向图的物联网环境下多智能体系统灵敏度分析方法,将多智能体系统看作为一个加权无向图,通过构建一阶智能体、输入饱和的一阶智能体以及二阶智能体模型,确定多智能体系统初始条件,实现系统运行状态分析。根据系统运行状态,确定系统信息传输的时滞,并对物联网下多智能体系统导纳进行计算,通过对系统的时滞和导纳进行微分,实现物联网环境下多智能体系统灵敏度分析。实验结果表明,所提方法进行灵敏度分析,执行时间较短,分析速度较快,且分析过程中对计算机网速影响较小。A method to analyze the sensitivity of multi-agent system in Internet of Things environment based on weighted undirected graph was proposed.At first,the multi-agent system was regarded as a weighted undirected graph.By constructing a first-order agent and inputting the saturated first-order agent and second-order agent model,the initial condition of multi-agent system was determined and the analysis of system operation status was achieved.According to the operating status of system,the time lag during system information transmission was determined and the admittance of the multi-agent system in the Internet of Things was calculated.Through differentiating the time delay and admittance of system,the sensitivity analysis of multi-agent system in Internet of Things environment was realized.Simulation results prove that when proposed method is used for sensitivity analysis.,the execution time is short and the analysis speed is fast.Meanwhile,the internet speed is less affected in analysis process.
