Analytic search methods in online social networks
(Massachusetts Institute of Technology, 2017)
This thesis presents and evaluates methods for searching and analyzing social media data in order to improve situational awareness. We begin by proposing a method for network vertex search that looks for the target vertex ...
A robust optimization approach to online problems
(Massachusetts Institute of Technology, 2017)
In this thesis, we consider online optimization problems that are characterized by incrementally revealed input data and sequential irrevocable decisions that must be made without complete knowledge of the future. We employ ...
Data-driven methods for personalized product recommendation systems
(Massachusetts Institute of Technology, 2018)
The online market has expanded tremendously over the past two decades across all industries ranging from retail to travel. This trend has resulted in the growing availability of information regarding consumer preferences ...
Stochastic models and data driven simulations for healthcare operations
(Massachusetts Institute of Technology, 2014)
This thesis considers problems in two areas in the healthcare operations: Kidney Paired Donation (KPD) and scheduling medical residents in hospitals. In both areas, we explore the implications of policy change through high ...
Data-driven models for uncertainty and behavior
(Massachusetts Institute of Technology, 2014)
The last decade has seen an explosion in the availability of data. In this thesis, we propose new techniques to leverage these data to tractably model uncertainty and behavior. Specifically, this thesis consists of three ...
Prediction and optimization in school choice
(Massachusetts Institute of Technology, 2016)
In this thesis, I study how data-driven optimization can be used to improve school choice. In a typical school choice system, each student receives a set of school options, called the student's menu. Based on his/her menu, ...
Advances in robust and adaptive optimization : algorithms, software, and insights
(Massachusetts Institute of Technology, 2016)
Optimization in the presence of uncertainty is at the heart of operations research. There are many approaches to modeling the nature of this uncertainty, but this thesis focuses on developing new algorithms, software, and ...
Optimization and equilibrium in dynamic networks and applications in traffic systems
(Massachusetts Institute of Technology, 2015)
This thesis discusses optimization problems and equilibrium in networks. There are three major parts of the thesis. In the first part, we discuss optimization in dynamic networks. We focus on two fundamental optimization ...
Pricing for retail, social networks and green technologies
(Massachusetts Institute of Technology, 2015)
What is the right price to charge your customers? Many retailers and researchers are facing this question. In the last three decades, tremendous progress was made, both in the academic and business worlds. In this thesis, ...
Velocity-based storage and stowage decisions in a semi-automated fulfillment system
(Massachusetts Institute of Technology, 2016)
The supply chain management for an online retailing business is centered around the operations of its fulfillment centers. A fulfillment center receives and holds inventory from vendors, and then uses this inventory to ...
