Abstract

The paper deals with a stochastic behavior of a two-identical unit cold standby system model assuming three modes- normal, partially failure and total failure of the units. A totally failed unit needs some preparation work before going into repair and after completion of preparation, the unit is sent for repair. A partially failed unit may operate with reduced efficiency while it is undergoing repair. A single repairman plays the triple role  the repair of partially failed unit, the preparation for repair of totally failed unit and repair of totally failed unit. The repair discipline is FCFS in respect of above three jobs. The various measures of system effectiveness are obtained by using regenerative point technique.
