A Two Dissimilar Unit Standby System with Waiting Time of Repairman and Correlated Failure and Repair Times
Pradeep Chaudhary , Anika Sharma
Abstract
The paper deals with the analysis of a system composed of two non-identical units (unit-1 and unit-2). Initially, unit- 1 is operative and unit-2 is kept in cold standby. Each unit has two possible modes- Normal (N) and Total Failure (F). The repairman is not always available with the system. As soon as a unit fails, he is called to come at the system for making the repair of failed unit and he takes some significant time to reach at the system. This time is known as waiting time of the repairman. The system failure occurs when both the units are in total failure mode. The joint distribution of failure and repair times for each unit is taken as bivariate exponential. Each repaired unit works as good as new. Using regenerative point technique, various important measures of system effectiveness have been obtained.
