摘要
In this paper discrete aging intensity and discrete alternative aging intensity functions are introduced. Further, using these functions we characterize some Discrete Weibull related distributions. Although, these discrete distributions have their continuous equivalents, quite often they seem to be more convenient in reliability analysis of elements and systems. Finally, for the considered class of Modified Discrete Weibull distributions a discrete aging intensity order is studied. This order allows us to decide that one random variable has the better aging property than the other one. (C) 2016 Elsevier B.V. All rights reserved.
