Abstract

For certain classes of customers, the ergodic number of customers in system (queue) and the ergodic time spent in system (queue) are related by a distributional form of Little's Law [7]. When such a class satisfies modest auxiliary conditions, a structurally simple decomposition of the number in system of the form of Fuhrmann and Cooper [3] is present. This decomposition is implemented for several queueing systems and is shown there by to provide a degree of unification to queueing theory.
