【摘要】 作为未来天基信息系统的发展方向,网络化天基系统能够在用户任务的驱动下更加快速、连续地获取和处理多类信息。本文以抗震救灾为应用背景,分析了系统的工作流程和主要任务,构建了多任务层次的系统连续性效能指标体系,度量了系统返回信息的密集程度。根据连续性指标特点,建立了基于灰色评估法的效能评估模型。利用仿真统计数据给出了算例,综合得到连续性效能评估结果,同时提供了连续性效能在每一个任务层次的具体评估细节,对寻找影响系统效能的瓶颈因素、确立我国天基信息系统的发展重点都具有重要的指导意义。更多还原

【Abstract】 As the trend of future space based information system,networked space based information system can acquire and process all sorts of information more quickly and continuously under the user task scheduling.In the background of earthquake relief for applications,working flow and main tasks of the system are analyzed,and continuity effectiveness evaluation index system is constructed in multi-task level.The continuity effectiveness is a measurement of intensive degree of information returned.Evaluation model based on greyevaluation method is constructed and different reference indexes are used for different tasks.Examples are given by using statistical data in simulation,and the integrative evaluation results are obtained.Detailed evaluation results in every specific task level are offered,which are helpful to find out the effectiveness bottleneck factors meanwhile provide guidance in system design and development.更多还原
