Abstract

The authors consider queueing that occur naturally in the study of a class of resource-sharing problems under synchronization constraints such as resequencing and fork-join primitives. These queueing models are amenable to a representation in terms of a state recursion. The proposed methods of analysis are complementary and draw on classical ideas of queuing theory as well as on mathematical tools from the theory of stochastic ordering and ergodic theory. The state recursion is at the center of all aspects of the analysis, be it for developing the exact solutions, obtaining bounds on system performance or establishing the stability conditions. The ideas are illustrated on simple models of resequencing and fork-join synchronization, which emphasis put on deriving computable bounds on the performance measures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
