【Abstract】 In this paper,we consider a queueing system with two heterogeneous servers of different service rates,in which Server 1 is perfectly reliable and Server 2 is subject to breakdown.Using the quasi-birth-and-death process method,we derive the equilibrium condition of the system and the matrix-geometric solution of the steady-state probability vectors.Some performance measures of the system and numerical results are obtained.更多还原
