Purpose – The purpose of this paper is to solve the maintenance management problems of generating units under the reliability criterion. Design/methodology/approach – The problem has been formulated as a combinatorial optimization task, with explicit and simultaneous treatment of multiple...

We address the performance optimization problem in a single-station multiclass queueing network with changeover times by means of the achievable region approach. This approach seeks to obtain performance bounds and scheduling policies from the solution of a mathematical program over a relaxation...

We address the problem of scheduling a multi-station multiclass queueing network (MQNET) with server changeover times to minimize steady-state mean job holding costs. We present new lower bounds on the best achievable cost that emerge as the values of mathematical programming problems (linear,...
