Statistical distributions are useful in predicting patterns of failure and hence, are employed in failure and reliability analysis. Reliability analysis is relatively easier when time variance is linear. However, for a non-linear progression of time such as the case in preventive maintenance, the reliability analysis becomes complex. This paper primarily investigates characteristics of exponential distribution taking into account periodic preventive maintenance. As a secondary consideration, the paper also investigates characteristics of Weibull distribution to provide a platform for comparison.
