一种面向需求的综合化系统健康度量方法

摘要

研究航空电子综合化系统中的预兆与健康管理问题,定义综合化系统的物理健康与逻辑健康,描述综合化系统的需求和资源,运用系统工程分析法,将应用层面的任务需求与物理层面的资源有效性相结合,提出一种面向需求的资源平台健康度量算法.给出综合化系统的资源重构模型,并论述关于综合化系统健康决策中的健康分级与系统重构问题.%This paper studies the problems of prognostics and health management in avionics integrated system, and gives the two definitions of physical health and logical health. It investigates the relationship between requirement and resource of system by depicting them and combining mission requirements on application level and resources availability on physical level. It proposes a demand-oriented algorithm to measure system health for integrated system. Besides it establishes a reconfiguration mathematics model and describes the health ranking and system reconfiguration in the decision-making of integrated system.
