Abstract :This paper investigates the possible incorporation of the variability of a failure durations observation series into reliability estimates considering failure time series {3, 3, 5, 6, 6.2657} and {2.5097, 4.0678, 4.9942, 5.6460, 6.1684} with very similar mean and variance. The first series of failures of a device would yield the feeling of having a failure in the duration of the third period. Later on, it would have a user experience of failing anytime. The aim of the paper is to investigate how variant conditions can be incorporated into a reliability estimate. For this purpose, distinct schemes were chosen. Initial consideration was the averaging of estimated reliability functions predicted for different deviations. Later considerations involved estimating a single standard deviation figure by averaging possible deviations. Thirdly, is the normalized version of the preceding method. The conclusions drawn from the observations indicate consideration of variability into reliability calculations impacting the estimates, which would be dependent on operational conditions, such as reset costs and safety needs.
