Abstract

For any system reliability calculation, estimation plays a vital role and hence the analysis is to be diverted to calculate reliabilities of the units. To do this, we need to analyze failure rates or inter-failure time intervals or duration of the failure free operation of the units. This data is usually termed as Working Hours (successive failures). Working Hours implies that the gap between failure to failure which is directly linked with the reliability of the system. Hence in this paper, first we fit and test the suitability of the data using Exponential and Weibull distribution through chi-square Goodness of Fit (GoF) test. In the later part, reliabilities of different units are calculated using the same distributions. Conclusions are drawn based on the results obtained.
