| 摘 要： | 为应用基于状态的装备可靠度模型，实现对装备的精确维修，采用了比例风险模型（Proportional Hazards Model，PHM）将装备的年龄信息及检测所得状态信息融入系统的风险函数中。考虑到样本包含截尾数据的情形，应用极大似然估计方法对模型中的参数进行了估计以及相应的模型检验。通过对该方法在一个实际案例中应用的详细分析，验证了方法的可行性。

| Abstract: | In order to achieve precision maintenance by Condition Based equipment reliability model, this paper uses the Proportional Hazards Model （ PHM ） to incorporate the ages and conditions information of equipment into the system＇s hazards function. Considering the censored data in the samples, maximum likelihood method is used to estimate the parameters in the model and model test methods are also discussed. Its application in a case study validates the feasibility of the method. |
