Modelling Approaches to Failures

Modelling of failures is an important element of reliability modelling. The approach to modelling depends on the kind of information available and the goal of the modelling. Empirical modelling approach suitable for complex item is explored in this paper. First step of the empirical modelling approach is to plot hazard function, density function, Weibull probability plot as well as cumulative intensity function to see which model fits best for the given data. Next step of the empirical modelling approach is select appropriate model for the data and fit the parametric model accordingly and estimate the parameters.
