Diffusion-Based Policies for Dynamic Control of Stochastic Processing Networks
Baris Ata, Jin Guang, J. Michael Harrison +1
We consider a processing network model with job classes or buffers, exogenous input flows into some classes, processing activities, and servers. Each activity is either…
Dynamic Scheduling of a Parallel-Server Queueing System: A Computational Method for High-Dimensional Problems
Baris Ata, Ebru Kasikaralar
A key operational challenge for call centers is to decide, in real time, which waiting customer should be served by which available agent. This is known as skill-based routing, and…
Dynamic control of stochastic matching systems in heavy traffic: An effective computational method for high-dimensional problems
Baris Ata, Yaosheng Xu
Bipartite matching systems arise in many settings where agents or tasks from two distinct sets must be paired dynamically under compatibility constraints. We consider a high-dimens…
Dynamic Scheduling of a Multiclass Queue in the Halfin-Whitt Regime: A Computational Approach for High-Dimensional Problems
Baris Ata, Ebru Kasikaralar
We consider a multi-class queueing model of a telephone call center, in which a system manager dynamically allocates available servers to customer calls. Calls can terminate throug…
Analysis and Improvement of Eviction Enforcement
Baris Ata, Yuwei Zhou
Each year, nearly 13,000 eviction orders are issued in Cook County, Illinois. While most of these orders have an enforcement deadline, a portion does not. The Cook County Sheriff's…
