An ODE for an Overloaded X Model Involving a Stochastic Averaging Principle
Ohad Perry, Ward Whitt
We study an ordinary differential equation (ODE) arising as the many-server heavy-traffic fluid limit of a sequence of overloaded Markovian queueing models with two customer classe…
Diffusion Approximation for an Overloaded X Model Via a Stochastic Averaging Principle
Ohad Perry, Ward Whitt
In previous papers we developed a deterministic fluid approximation for an overloaded Markovian queueing system having two customer classes and two service pools, known in the call…
Integer Sequences from Queueing Theory
Joseph Abate, Ward Whitt
Operators on probability distributions can be expressed as operators on the associated moment sequences, and so correspond to operators on integer sequences. Thus, there is an oppo…
A Fluid Limit for an Overloaded X Model Via a Stochastic Averaging Principle
Ohad Perry, Ward Whitt
We prove a many-server heavy-traffic fluid limit for an overloaded Markovian queueing system having two customer classes and two service pools, known in the call-center literature…
Continuity of a queueing integral representation in the topology
Guodong Pang, Ward Whitt
We establish continuity of the integral representation , , mapping a function into a function when the underlying function space is…
