摘要

The Proportional Hazard Model (PHM) is very flexible to incorporate categorical and continuous variables to the survival analysis. The model can be used to assess the risk of a set of covariates with immediate application for repeated events with multiple failure modes in many electromechanical appliances. The major advantage of not requiring a parametric equation is subjected to some challenges for a direct estimation of the survival curve, as the model is developed in terms of the hazard function. Hazards models can be easily used when operating conditions or consumer usage pattern are to be assessed, such as the experiment used in this research.
