Abstract: Excessive systems| usage leads to failure and hence necessitates repair or replacement. Many types of repair actions could be implemented after failure. In this work, the performance of a system that is upon failure could undergo one of several repairs; imperfect repair, minimal repair, or replacement (perfect repair), is examined. An analytical expression for the availability of the general system and three special cases are derived along with the long run probabilities of the different states of the system. An example is presented to illustrate and compare the performance of the three cases.

Keywords: imperfect repair; minimal repair; replacement; system failure; analytical expression; repair options; system availability.
