Abstract

In this paper, we study an M/M/2 queueing system with multiplevacations where the service rates of the servers are not identical.This queuing system has been analyzed as a quasi-birth and deathprocess by Kumar and Madheswari (2005). However, by expressing the ratematrix explicitly, we have obtained a explicit expression of thestationary distribution of the queue length. The conditionalstochastic decomposition properties of the queue length and thewaiting time have been also established for such a system.

Highlights

  • We study an M/M/2 queueing system with multiple vacations where the service rates of the servers are not identical

  • The conditional stochastic decomposition properties of the queue length and the waiting time have been established for such a system

  • A queueing system with two heterogeneous servers and multiple vacations was studied by Kumar and Madheswari (2005), who obtained the stationary queue length distribution by using a matrix geometric method and provided an analysis of busy period and waiting time
