#### Matrix-Geometric Solution for Two Node Tandem Queueing Systems with Phase-Type Servers Subject to Blocking and Failures.

(1987)

A two node tandem queueing system with phase-type servers and Bernoulli arrivals is considered in discrete-time when servers are subject to bloclring and failuree. The invariant probability vector of the underlying finite ...

#### Parameter Estimation under Threshold Policies for a Simple Flow Control Problem.

(1987)

In [5], the authors showed that threshold policies solve an optimal flow control problem for discrete-time M|M|1 queues, where the decision-maker seeks to maximize the system throughput subject to a bound on the long-run ...

#### Multi-Dimensional Stochastic Ordering and Associated Random Variables.

(1987)

This paper presents several relationships between the notion of associated random variables and notions of stochastic ordering which have appeared in the literature over the years. More concretely, the discussion centers ...

#### Analysis and Adaptive Control of a Discrete-Time Single-Senrer Network with Random Routing.

(1989)

This paper considers a discrete time system composed of K infinite capacity queues that compete for the use of a single server. Customers arrive in i.i.d batches and are served according to a server allocation policy. Upon ...

#### Discrete-Time Filtering for Linear Systems in Correlated Noise with Non-Gaussian Initial Conditions.

(1989)

We consider the one-step prediction problem for discrete-time linear systems in correlated plant and observation noises, and non-gaussian initial conditions. Explicit representations are obtained for the MMSE and LMSE ( ...

#### Analysis and Adaptive Control of a Discrete-Time Single-Server Network with Random-Routing.

(1989)

This paper considers a discrete-time system composed of K infinite capacity queues that compete for the use of a single server. Customers arrive in i.i.d batches and are served according to a server allocation policy. Upon ...

#### Discrete-Time Filtering for Linear Syskms in Correlated Noise with Non-Gaussian Initial Conditions: Asymptotic Behavior of the Difference between the MMSE and LMSE Estimates.

(1989)

We consider the one-step prediction problem for discrete-time linear systems in correlated plant and observation noises, and non-gaussian initial conditions. We investigate the asymptotic behavior of the expected square ...

#### A Simple Problem of Flow Control I: Optimality Results.

(1987)

This paper presents a problem of optimal flow control for discrete M|M|1 queues. The problem is cast as a constrained Markov decision process, where the throughput is maximized with a bound on the average queue size. By ...

#### Simple Proofs of Some Folk Theorems for Parallel Queues.

(1989)

We present simple proofs of some folk theorems for systems of identical single server queues operating in parallel. In particular we establish a monotonicity property in the number of servers, and show that round-robin ...

#### Matrix-Geometric Solution for Finite Capacity Queues with Phase- Type Distributions.

(1987)

This paper presents a class of Quasi-Birth-and-Death processes with finite state space for which the invariant probability vector is found to admit a matrix-geometric representation. The corresponding rate matrix is given ...
