Cost optimization of an M/M/r queueing system with queue-dependent servers: genetic algorithm

Abstract

We consider an M/M/r queueing system with infinite capacity, in which the number of working servers changes depending on the queue length. The steady-state probability distributions and the expected number of customers in the system are derived, which are used to construct a cost function. In order to minimize the expected cost of the system, we use the… (More)
