Comparison of two identical reliability models for two unit system with model-1 “three types of repair policy” and model-2 “three types of repair policy and replacement


Author(s): Rashmi Gupta

Abstract: The present paper deals with the comparison of two identical reliability models for two unit system with model-1 “three types of repair policy” and model-2 “three types of repair policy and replacement”. On the failure of the unit, it is first undertaken by the ordinary repairman who may not be able to do some complex repairs and may rather damage the unit during try for its repair. On the inability shown by the ordinary repairman, the unit is undertaken for repair by the expert repairman adopting one of the three types of repair policy. The damage unit may or may not be repairable and hence is repaired/replaced accordingly.
Various measures of system effectiveness have been obtained by making use of semi-Markov processes and regenerative point technique in both the models. Graphical study for a particular case is made and various cut-off points for making the decisions regarding profitability of the system have been obtained.
