Abstract:For the repairable multi-state component, reliability indexes are analyzed based on a homogenous Continuous Time Markov Chain (CTMC). If the component can work well when its repair time is sufficiently short, a threshold value for maintenance is introduced. When the fault interval is less than threshold time, the fault effect is considered neglected. In this paper; comparisons of availability show differences of the new model and the original model with or without fault interval omission. In addition, balancing the maintenance cost and lifetime of multi-state components is an important issue when threshold values are considered. Both constants and non-negative random variables are modeled respectively. Finally, numerical examples are presented to illustrate the results obtained in this paper.
