L. Wenocur, Michael, A reliability model based on the gamma process and its analytic theory, Advances in applied probability , 21(4), 1989, pp. 899-918
This paper presents a variation of a state-dependent reliability model first proposed in Lemoine and Wenocur [4], [5], and develops some of its corresponding analytical theory. In particular, we develop a reliability model in which system state is a random process satisfying a stochastic differential equation where the driving process is gamma distributed.
