  Abstract:
  We study a single-server discrete-time queueing model with general independent arrivals and a two-component service process. Each customer represents a service demand: a random, arbitrarily distributed number of work units. The server disposes of a constant service capacity, i.e., a fixed number of work units that can be executed per time slot. We obtain closed-form results for the probability generating functions of the unfinished work in the system, the queueing delay of an arbitrary customer and, in a number of special cases, the number of customers in the system.
