Algorithms for second moments in batch-movement queueing systems

Some recent papers in the literature detail how mean-value analysis may be applied to an important class of batch-movement queueing systems and stochastic 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.
