%X 提出了基于健康状态 广义测试相关性（health state-general test, 简称HSGT）的健康状态评估技术。首先，根据维修要求将故障严重程度划分成多个离散的健康状态，再按测试输出属性，将测试划分为一系列区间值的广义测试，进而结合系统功能与结构等信息，建立系统健康状态-广义测试相关性矩阵；其次，利用贝叶斯理论，建立基于HSGT的健康状态评估推理模型；最后，使用蒙特卡洛方法生成包含８个被测单元（unit under test, 简称UUT）的系统，对所提技术的有效性及可行性进行了仿真验证。结果表明，提出的健康状态评估技术能根据系统测试输出结果，及时、准确地推理出系统中各个UUT的健康状态，评估结果能在故障加剧导致的功能失效前有效触发视情维修(condition based maintenance,简称CBM)的维修决策机制。<br>Health state assessment (HSA) which integrates structural and functional information of unit under test (UUT) can provide data support for maintenance decision of Conditon Based Maintenance (CBM). HSA technology based on health state-general test (HSGT) dependency is proposed in this paper. Firstly, according to different maintenance requirements, the degrees of fault severity are divided into several health states and the test ranges which are discretized by several general tests, thus a HSGT matrix can be built by integrating structural and functional information of a system. Secondly, the Bayesian theory is used to model HSA based on HSGT. Finally, the Monte Carlo simulation method is developed to build an eight-UUT system, and the effectiveness and feasibility of the proposed method is verified. The experimental results show that the proposed HSA technique can assess health states of UUTs in a timely and accurately way, and the assessment results can trigger the maintenance decision prior to functional failures due to fault growth.
