Data-Driven Decision Making in Operations Management
(Massachusetts Institute of Technology, 2023-06)
Encouraged by the plethora of advances in artificial intelligence (AI) in the past decade, this thesis studies the length to which we can push various business operations with new technologies, in our theoretical understanding ...
Distributionally robust optimization with marginals : theory and applications
(Massachusetts Institute of Technology, 2019)
In this thesis, we consider distributionally robust optimization (DRO) problems in which the ambiguity sets are designed from marginal distribution information - more specifically, when the ambiguity set includes any ...
Data-driven optimization with behavioral considerations : applications to pricing
(Massachusetts Institute of Technology, 2019)
This thesis aims to introduce descriptive and predictive models that guide more informed pricing strategies in practice, drawing from interdisciplinary work of current OM, behavioral theories and recent machine learning ...
Prescriptive analytics in operations problems : a tree ensemble approach
(Massachusetts Institute of Technology, 2019)
The main contributions of this thesis concern addressing challenges in the field of prescriptive optimization, and how machine learning techniques can be incorporated into solving data-driven operational optimization ...
New Theory and Algorithms for Convex Optimization with Non-Standard Structures
(Massachusetts Institute of Technology, 2023-06)
Optimization models and algorithms have long played central and indispensable roles in the advancement of science and engineering. In recent years, first-order methods have played important roles in tackling applications ...
Robust optimization, game theory, and variational inequalities
(Massachusetts Institute of Technology, 2005)
We propose a robust optimization approach to analyzing three distinct classes of problems related to the notion of equilibrium: the nominal variational inequality (VI) problem over a polyhedron, the finite game under payoff ...
An Operations Research approach to aviation security
(Massachusetts Institute of Technology, 2005)
Since the terrorist attacks of September 11, 2001, aviation security policy has remained a focus of national attention. We develop mathematical models to address some prominent problems in aviation security. We explore ...
Tractable multi-product pricing under discrete choice models
(Massachusetts Institute of Technology, 2013)
We consider a retailer offering an assortment of differentiated substitutable products to price-sensitive customers. Prices are chosen to maximize profit, subject to inventory/ capacity constraints, as well as more general ...
Integration of predictive routing information with dynamic traffic signal control
(Massachusetts Institute of Technology, 1994)
New results in flow line analysis
(Massachusetts Institute of Technology, 1995)
