摘　　要：随着航空电子系统的集成化与自动化程度不断提高,其潜在的故障多发可能性随之提高,可靠性与有效性降低、健康状态变差。针对航空装备状态健康度量目标,以系统能力有效性层次化结构组织为框架,给出系统健康、预兆、系统能力以及系统健康等级的定义,建立通用系统健康体系架构,提出以系统有效性为主导的健康状态管理思路,通过对装备资源健康状态、功能健康状态和任务健康状态的评估,实现系统健康状态等级的划分,并给出健康状态等级形式化定义。以航空电子系统为对象进行实验分析。结果表明,方法显著提高了航空电子系统健康状态评估的准确性。With the integration and automation of the avionics system improving continuously,the possibility of the potential failure is increased,and the reliability,validity and health state are reduced.The health management of the avionics system is a new and important research topic,which is still without a clear specification and definition.Based on the research of the avionics system health characteristics,we gives the definitions of system health,system capacity and health classes for the first time.According to the system characteristics,a new idea of health state management based on system effectiveness is put forward.And then the formal definition of health status is given based on the resource and function health state.Apply the proposed method to aircraft avionics system,the results show that,the method proposed has remarkable achievement on accuracy of health state diagnosis of aircraft avionics system.

关 键 词：健康管理 健康状态等级 资源有效性 功能有效性
