Remaining useful life (RUL) estimation is an important part in modern prognostic and health management (PHM) approach. In this paper, a particular prognostic named similarity-based RUL estimation is proposed. In some complex condition, typical methods will perform inefficient, and in engineering application background, some traditional methods may be hard implemented. On the other hand, similarity-based...
First, the model of equipment remaining usage life prediction based on the grey system theory is established. According that, the remaining usage life prediction system is developed, and the main functional model is described. Then, the Weibull proportional hazards model (PHM) is used to establish the failure rate model based condition data. Besides, we have considered the model parameter estimation...
