摘要:

针对卫星信息应用链任务处理能力评估问题,分析了卫星信息应用链任务处理的基本过程,建立了卫星信息任务处理过程的网络模型。利用排队网络方法分析了卫星应用信息链期望情况下的任务处理能力,利用网络演算方法分析卫星应用信息链最差情况下的任务处理能力。通过案例研究对比了两种评估方法,得出了卫星应用信息链任务处理能力的期望性能和最差的性能。

Abstract:

To solve tasking capability evaluation of satellite information application chain, the basic process of satellite information application chain is analyzed, and a network model of the process is built. The expected capacity is evaluated by the method of queuing network, and the worst capacity is evaluated by the method of network calculus. A case is studied to compare two evaluation methods, and the expected and worst performance of satellite information application chain tasks processing are obtained.
