Abstract

This paper deals with the stochastic analysis of a system having three parallel identical operating units with two types of repair. Whenever any operating unit fails it goes to repair. There is a two phase independent repair facility to repair the failed units on first come first serve basis. Whenever an operating unit fails its goes to phase I repair first. After the completion of first phase repair the unit goes to Phase II repair. After the completion of total repair i.e. Phase I repair and Phase II repair unit works as a new unit. All the failure and repair time distributions are assumed to be negative exponential. Various reliability characteristics are obtained in order to analyze the expected profit earned by the system.
