Abstract

Neglect of simultaneous resource possession is a significant problem with queueing network models of computers. This is illustrated by examples of memory contention and channel contention with position sensing I/O devices. A class of extended queueing networks is defined to allow representation of simulataneous resource possession. Extended queueing network models of memory contention and channel contention are given. Solution techniques and numerical results for these models are discussed.
