Marked point processes (MPP's) play an important role in stochastic modeling. In this talk we
review a class of point processes, called batch Markovian arrival processes (BMAP's), that is …

We consider a branch of queueing theory, retrial queueing systems, which is characterized
by the following basic assumption: a customer who cannot receive service (due to finite …

Nursing care is arguably the single biggest factor in both the cost of hospital care and patient
satisfaction. Inadequate inpatient nursing levels have also been cited as a significant factor …

We develop a simple algorithm to compute the rate matrices of ergodic level-dependent
quasi-birth-and-death processes, based on a matrix continued fraction representation and a …

We consider a single server queue in which the customers wait for service for a fixed time
and leave the system if the service has not begun within that time. The customers arrive …

In this paper we develop approximation models for feed-forward networks of G/G/1/N
queues. We use Linear Algebra Queueing Theory (LAQT) techniques to create reduced …

This book is about efficient communication. The role of communication, as a means for the
transmission of information among people, is one of the key factors driving the development …

We present a novel numerical method that exploits invariant subspace computations for
finding the stationary probability distribution of a finite QBD process. Assuming that the QBD …

In this paper, we study the performance of service systems with priority upgrades. We model
the service system as a single-server two-class priority queue, with queue 1 as the normal …

Two stage open queuing networks are used for modeling the subsystem-behaviour in
computers and communication networks, mass storage devices, memory servers, and …
