Last, Gunter, Ergodicity properties of stress release, repairable system and workload models, Advances in applied probability , 36(1), 2004, pp. 471-498
In this paper we derive some of the main ergodicity properties of a class of Markov renewal processes and the associated marked point processes. This class represents a generic model of applied probability and is of importance in earthquake modeling, reliability theory and queueing.
