Some recent papers in the literature detail how mean-value analysis may be
applied to an important class of batch-movement queueing systems and stocha
stic Petri nets. The techniques may be applied, inter alia, to the analysis
of circuit-switched networks and slotted-ring networks. The present paper
describes a development of these ideas to provide a basis for the efficient
calculation of second and higher moments. (C) 2000 Elsevier Science Ltd. A
