An Open Priority Queuing System for Two Maintenance Operations

摘要

In the paper a multi-component redundant system with unreliable, repairable units is considered. Two types of maintenance operations are performed in the system: 1) the replacement of the failed main unit by the redundant one; 2) the repair of the failed unit. The open priority queuing model for the system's dependability and performability analysis is constructed in the form of infinite system of ordinary linear differential equations. In steady state it is reduced to the infinite system of linear algebraic equations.
