Abstract

Effective maintenance management is essential to reduce the adverse effect of equipment failure to operation. This is accomplished by accurately predicting the equipment failure such that appropriate actions can be planned and taken in order to minimize the impact of equipment failure to operation. This paper presents a development of model based on Markov process for a degraded multi-state system to evaluate the system performance. The system degradation was quantified by five distinct level of system’s production output ranging from perfect functioning state to complete failure with zero output. At any point in time, the system can experience Poisson failure from any state upon which an imperfect repair will be performed while imperfect preventive maintenance will be performed at the last acceptable state as indicated by minimum acceptable production output. This research explored a method of estimating of transition matrix for the five state Markov process by utilizing production output data. The results indicate the applicability of Markov where comparison with traditionally binary model is presented.
