This paper deals with an Mx=G=1 queueing system with two phases of heterogeneous service under N-policy, where the server remains idle till the queue size becomes NðP1Þ. As soon as the queue size becomes N, the server immediately starts first essential service for all the units. After completion of the essential service of a unit, it may leave the system with probability (1 h) or may immediately go for a second phase of service in an additional service channel with probability h (06h61). For this model, we derive the queue size distribution at a random epoch as well as at a departure epoch. Further, we derive some important performance measures of this model. This is a generalization of recent papers considered by Medhi [Queueing Systems 42 (2002) 239] and Lee et al. [Queueing Systems 15 (1994) 387]. 2003 Elsevier Inc. All rights reserved.
