Abstract
Reliability growth is defined as the positive progress in reliability over a period of time according to changes in product design or manufacturing processes. There are three main areas of reliability growth: planning, tracking and projecting. The most important model is the tracking models The model parameters were estimated using the maximum potential method as well as estimation of the confidence intervals for these parameters, estimation of the confidence intervals for the time-to-time ratio (DMTBF), and finally the model was simulated using the Monte Carlo method using specialized software (RGA)
