Optimization-based routing and scheduling of IED-detection assets in contemporary military operations
(Massachusetts Institute of Technology, 2009)
Improvised Explosive Devices, or IEDs, have become a familiar and lethal part of contemporary military operations in Iraq and Afghanistan, producing more casualties than any other weapons system. One reason for their success ...
Interception algorithm for autonomous vehicles with imperfect information
(Massachusetts Institute of Technology, 2005)
Autonomous vehicles often operate in environments with imperfect information. This thesis addresses the case of a system of autonomous vehicles and sensors attempting to intercept a moving object of interest that arrives ...
A decision analytic approach to Web-based clinician training
(Massachusetts Institute of Technology, 2005)
Given the desire to create interactive websites that effectively engage and instruct medical professionals, an alternative model for online case studies was developed. The resulting application presents the user with a ...
Robust estimation, regression and ranking with applications in portfolio optimization
(Massachusetts Institute of Technology, 2009)
Classical methods of maximum likelihood and least squares rely a great deal on the correctness of the model assumptions. Since these assumptions are only approximations of reality, many robust statistical methods have been ...
A new approach to multistage serial inventory systems
(Massachusetts Institute of Technology, 2001)
We consider a single product multistage serial inventory system with several installations, say N - I, ... , l. Installation N - I intakes exogenous supply of a single commodity. For i E {I, ... N - 2}, installation i is ...
Restaurant revenue management
(Massachusetts Institute of Technology, 2002)
We develop two classes of optimization models in order to maximize revenue in a restaurant, while controlling average waiting time as well as perceived fairness, that may violate the first-come-first-serve (FCFS) rule. In ...
The cross section of expected stock returns revisited
(Massachusetts Institute of Technology, 2000)
We review and extend two important empirical financial studies: Fama and MacBeth [1973] and Fama and French [1992]. Fama and MacBeth [1973] sort stocks on the New York Stock Exchange into 20 portfolios based on their market ...
Robust, risk-sensitive, and data-driven control of Markov Decision Processes
(Massachusetts Institute of Technology, 2007)
Markov Decision Processes (MDPs) model problems of sequential decision-making under uncertainty. They have been studied and applied extensively. Nonetheless, there are two major barriers that still hinder the applicability ...
Selfish versus coordinated routing in network games
(Massachusetts Institute of Technology, 2004)
A common assumption in network optimization models is that a central authority controls the whole system. However, in some applications there are independent users, and assuming that they will follow directions given by ...
Coordinating inventory control and pricing strategies
(Massachusetts Institute of Technology, 2003)
Traditional inventory models focus on effective replenishment strategies and typically assume that a commodity's price is exogenously determined. In recent years, however, a number of industries have used innovative pricing ...
