Control of the Multiclass G/g/1 Queue in the Moderate Deviation Regime1 by Rami Atar

چکیده

A multi-class single-server system with general service time distributions is studied in a moderate deviation heavy traffic regime. In the scaling limit, an optimal control problem associated with the model is shown to be governed by a differential game that can be explicitly solved. While the characterization of the limit by a differential game is akin to results at the large deviation scale, the analysis of the problem is closely related to the much studied area of control in heavy traffic at the diffusion scale.

Asymptotically Optimal Control for a Multiclass Queueing Model in the Moderate Deviation Heavy Traffic Regime1 by Rami Atar

A multi-class single-server queueing model with finite buffers, in which scheduling and admission of customers are subject to control, is studied in the moderate deviation heavy traffic regime. A risk-sensitive cost set over a finite time horizon [0, T ] is considered. The main result is the asymptotic optimality of a control policy derived via an underlying differential game. The result is the...

Optimality of the generalized $$\varvec{c\mu }$$ c μ rule in the moderate deviation regime

This paper studies a multiclass queueing system with an associated risksensitive cost observed in heavy traffic at the moderate deviation scale, accounting for convex queue length penalties. The main result is the asymptotic optimality of a dynamic index policy known from the diffusion-scale heavy traffic literature as the generalized cμ rule.

On the non-Markovian multiclass queue under risk-sensitive cost

This paper studies a control problem for the multiclass G/G/1 queue for a risk-sensitive cost of the form n logE exp ∑ i ciX n i (T ), where ci > 0 and T > 0 are constants, X n i denotes the class-i queue length process, and the number of arrivals and service completions per unit time are of order n. The main result is the asymptotic optimality, as n → ∞, of a priority policy, provided that ci ...

An Asymptotic Optimality Result for the Multiclass Queue with Finite Buffers in Heavy

For a multiclass G/G/1 queue with finite buffers, admission and scheduling control, and holding and rejection costs, we construct a policy that is asymptotically optimal in the heavy traffic limit. The policy is specified in terms of a single parameter which constitutes the free boundary point from the Harrison-Taksar free boundary problem, but otherwise depends explicitly on the problem data. ...

IRWIN AND JOAN JACOBS CENTER FOR COMMUNICATION AND INFORMATION TECHNOLOGIES A differential game for a multiclass queueing model in the moderate-deviation heavy-traffic regime

We study a differential game that governs the moderate-deviation heavy-traffic asymptotics of a multiclass single-server queueing control problem with a risk-sensitive cost. We consider a cost set on a finite but sufficiently large time horizon, and show that this formulation leads to stationary feedback policies for the game. Several aspects of the game are explored, including its characteriza...
