Evaluating the impact of performance goals on dispatching decisions in emergency medical service
IIE Transactions on Healthcare Systems Engineering, 1(3), 185–196.
TL;DR:
Examination of how the goal of maximizing coverage for different response time thresholds impacts patient survival rates in the context of emergency medical dispatch indicates that dispatching ambulances to maximize an eight minute response time threshold simultaneously maximizes patient survival.

2011 journal article
Joint management of capacity and inventory in make-to-stock production systems with multi-class demand
European Journal of Operational Research, 212(2), 312–324.
author keywords: Inventory; Dynamic programming; Flexible capacity; Joint control; Multi-class demand
TL;DR:
The model is formulated as a Markov decision process (MDP) and it is proved that a solution to the optimal joint control problem exists and that a simple heuristic that can adjust production capacity but uses a static production/rationing policy can result in significant savings.

2011 journal article
Predicting the solution time of branch-and-bound algorithms for mixed-integer programs
INFORMS Journal on Computing, 23(3), 392–403.
Contributors: O. Özaltin* , B. Hunsaker* & A. Schaefer *
author keywords: solution time prediction; mixed-integer programming; branch-and-bound algorithm
TL;DR:
A double exponential smoothing technique is proposed to predict the solution time of B&B algorithms and an evaluation method is evaluated using three MIP solvers to show that accurate predictions of the solutionTime are possible, even in the early stages of B &B algorithms.

Nonparametric Independence Screening in Sparse Ultra-High-Dimensional Additive Models
Journal of the American Statistical Association, 106(494), 544–557.
author keywords: Additive model; Independent learning; Nonparametric independence screening; Nonparametric regression; Sparsity; Sure independence screening; Variable selection
TL;DR:
This work shows that with general nonparametric models, under some mild technical conditions, the proposed independence screening methods have a sure screening property and the extent to which the dimensionality can be reduced by independence screening is also explicitly quantified.

Optimizing the Societal Benefits of the Annual Influenza Vaccine: A Stochastic Programming Approach
OPERATIONS RESEARCH, 59(5), 1131–1143.
Contributors: O. Özaltin* , O. Prokopyev *, A. Schaefer * & M. Roberts *
TL;DR:
This work quantifies the trade-offs involved through a multistage stochastic mixed-integer program that determines the optimal flu shot composition and its timing in a Stochastic and dynamic environment and incorporates risk sensitivity through mean-risk models.
