Performance of N machine centers of KoutofM: G type maintained by a single repairman

We consider a system of N (nonsymmetric) machine centers of the KoutofM : G type that are maintained by a single repairman. [A machine center functions if and only if at least K of the M machines belonging to the center are good (G).] Such systems are commonly found in various manufacturing and service industries. A stochastic model is developed that accommodates generally distributed repair times and repairman walk times, and most repair scheduling disciplines. KoutofM : G type systems also appear as a modeling paradigm in reliability analysis and polling systems performance analysis. Several performance measures are derived for machinerepair systems having KoutofMtype centers. A simple example system is developed in detail that exposes the computations involved in modeling applications. 1992 John Wiley & Sons, Inc. Copyright 1992 Wiley Periodicals, Inc., A Wiley Company
