Stage Method in Reliability System Analysis

Markovian models and their analysis techniques accomplish an important function in evaluating reliability/ availability in complex engineering systems. Markovian modeling is essentially associated with constant rate of transition from one state to another state of the system and is strictly applicable to exponential distributions. When a more general form for the distribution of a system component failure or repair is considered, a non Markovian process takes place. In this study the approach of the method of stages is analyzed, provided that, offers a great potential applicability to solve industrial problems. An application, for the Chilean copper mining sector is presented, since these modeling methodologies can optimize the activities of maintenance and production in this sector.
