Repair Replacement model for a Repairable system with two different repair actions using Alpha Series Process

K. Raja Sekhara Reddy, Dr. B. Venkata Ramudu

Abstract :

In this paper, the maintenance problem for a cold standby system consisting of two dissimilar components and one repairman with two repair actions is studied. Assume that the component 1 follow α–series process repair and is given priority in use while component 2 obeys a minimal repair. Under these assumptions, using an alpha series process repair model, we consider a replacement policy N under which the system is replaced when the number of failures of component 1 reaches N. The purpose of this paper is to determine an optimal replacement policy N* such that the average cost rate (i.e. the long–run average cost per unit time) of the system is minimized. The explicit expression for the average cost rate of the system is derived and the corresponding optimal replacement policy N* can be determined analytically or numerically. Finally, a numerical example is given to illustrate some theoretical results and the model applicability
