Dynamic reliability and performance evaluation of multi-state systems with two components

Abstract

In this paper we study multi-state systems consisting of two compo- nents when the number of system states and the number of states of each component are the same, i.e. the systems under consideration are homogeneous multi-state systems. In particular we evaluate multi-state series and cold standby systems assuming that the degradation in their components follow a Markov process. The behaviour of systems with respect to degradation rates is also investigated in terms of stochastic ordering.
