摘要

针对卫星信息应用链中数据处理的效能评估问题,给出一种基于Petri网理论的卫星信息应用链数据处理模型,确定相关的基本参数,分析在Petri网理论下卫星信息应用链节点的平均队长和平均等待时间,实现对卫星信息应用链数据处理效能的评估,为卫星信息应用链的资源优化配置提供支持.通过CPN Tools工具对所建Petri网模型进行仿真模拟得到各节点的性能指标.仿真结果表明,上述方法能够有效评估卫星信息应用链数据效能.%Aiming at the performance evaluation of data processing in satellite information application chain,a data processing model of satellite fnformation application chain based on Petri net theory is given to determine the relevant basic parameters,and the average queue length and the average waiting time of satellite information application chain nodes under Petri net theory are analyzed.And the performance evaluation of data processing for the satellite information application chain is achieved.Through the CPN Tools,the Petri net model is simulated and the performance of each node is obtained.The simulation results show that this method can effectively evaluate the data performance of satellite information application chain.
