Two topics in online auctions
(Massachusetts Institute of Technology, 2003)
This thesis studies two operations management topics in online auctions, and is divided into two parts. Motivated by the increasing use of ShopBots to scan Internet auctions, the first part of the thesis analytically ...
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 ...
Optimization of influenza vaccine strain selection
(Massachusetts Institute of Technology, 2003)
The World Health Organization (WHO) is responsible for making annual vaccine strains recommendation to countries around the globe. However, various studies have found that the WHO vaccine selection strategy has not been ...
Advances in airline revenue management and pricing
(Massachusetts Institute of Technology, 2003)
We propose new models and optimization methods for airline revenue management and pricing. In the first part of this thesis, we study the dynamic inventory control problem for a single flight under imperfect market ...
Constructing learning models from data : the dynamic catalog mailing problem
(Massachusetts Institute of Technology, 2003)
The catalog industry is a large and important industry in the US economy. One of the most important and challenging business decisions in the industry is to decide who should receive catalogs, due to the significant mailing ...
A Langrangian decomposition approach to weakly coupled dynamic optimization problems and its applications
(Massachusetts Institute of Technology, 2003)
We present a Lagrangian based approach to decoupling weakly coupled dynamic optimization problems for both finite and infinite horizon problems. The main contributions of this dissertation are: (i) We develop methods for ...
A profit maximization model in a two-echelon supply chain management : distribution and pricing strategies
(Massachusetts Institute of Technology, 2003)
Distribution and pricing strategies play a central role in the field of supply chain management. Heuristic approaches to the vehicle routing problem (VRP) are usually used to design optimal delivery routes to serve ...
Integer optimization in data mining
(Massachusetts Institute of Technology, 2003)
While continuous optimization methods have been widely used in statistics and data mining over the last thirty years, integer optimization has had very limited impact in statistical computation. Thus, our objective is to ...
Estimating the true extent of air traffic delays
(Massachusetts Institute of Technology, 2003)
Most air traffic delay measures assess delays relative to schedule. Over the past decades, however, airline schedules have been adjusted to take into account airspace congestion and yield better on-time performance. In ...
