Fluid queues to solve jump processes [PDF]

Performance Evaluation, 2005
We consider systems which exhibit a mixture of smooth behavior and occasional jumps, controlled by continuous-time Markovian processes on a finite state space, and we call these fluid queues with jumps, thereby emphasizing the fact that they constitute a generalization of fluid queues. We characterize their stationary distribution in an algorithmically

Invariant Measures for Fluid Queues

Stochastic Models, 2008
Positive recurrent fluid queues have a matrix-exponential stationary distribution. We show here that a transient or a null recurrent fluid queue also has a matrix-exponential invariant measure, which is not summable. We give a construction for this measure and we give the probabilistic interpretation for the key matrix that appears in the construction.

Stability for Fluid Queues: Characteristic Inequalities

Stochastic Models, 2013
We explore the conditions under which a fluid queue is positive recurrent, null recurrent, or transient. We consider the simple system where fluid rates are independent of the level, and exploit the similarity found by Ramaswami between fluid queues and Quasi-Birth-and-Death (QBD) processes.

Decomposition properties in fluid queues

Performance Evaluation, 2008
We discover two decomposition properties in certain fluid queues. In a queue fed by burst flows, the impact of flow dynamics over shorter timescales on the mean buffer length can be separated from the impact of flow dynamics over larger timescales. A queue with multiple inputs can be decomposed into multiple simpler queues and the two systems have the ...
