This paper presents an approximation method for numerically solving general Markov modulated fluid models which are widely used in modelling communications and computer systems. ...
We consider optimal policies for reentrant queues in which customers may be served several times at the same station. We show that for tandem reentrant queues the lastbuffer-fir...
In this paper we study monotonicity results for optimal policies of various queueing and resource sharing models. The standard approach is to propagate, for each specific model, ...
