Dynamic ship assignment problem with uncertain demands
(Massachusetts Institute of Technology, 2016)
Product tanker shipping companies in the spot market face severe volatility in demand and in price. We explore shipping companies' two problems: evaluating supply and demand of the market and assigning cargoes in order to ...
ChangiNOW : a mobile application for efficient taxi allocation at airports
(Massachusetts Institute of Technology, 2013)
The important role that taxis play in bringing passengers from an airport terminal to their final destination is often overlooked in airport operations and design. Due to varying flight arrival patterns at different ...
Service network design optimization for Army Aviation lift planning
(Massachusetts Institute of Technology, 2014)
The need for optimized aviation lift planning is becoming increasingly important as the United States and her allies participate in the Global War on Terror (GWOT). As part of a comprehensive effort, our nation's fighting ...
Understanding government and railroad strategy for crude oil transportation in North America
(Massachusetts Institute of Technology, 2014)
On July 6, 2013, an oil-laden unit train derailed and exploded in Lac-Megantic, Quebec, Canada, killing 47 people, shocking and saddening many, and leading to significantly increased public scrutiny of crude oil transported ...
Capacity management schemes for dual cabin aircraft : airline revenue management insights
(Massachusetts Institute of Technology, 2016)
The selection of an aircraft type has long term effects on the competitive position of the airline. In a market that is continuously evolving, such as the commercial aviation industry, any degree of flexibility for adjusting ...
Multi-model simulation-based optimization applied to urban transportation
(Massachusetts Institute of Technology, 2014)
Transportation agencies often resort to the use of traffic simulation models to evaluate the impacts of changes in network design or network operations. They often have multiple traffic simulation tools that cover the ...
Real time toll optimization based on predicted traffic conditions
(Massachusetts Institute of Technology, 2016)
Road pricing is an effective method of demand management. Pricing on highway managed lanes is usually implemented as time-of-day or dynamic tolling in practice. Toll rates are usually updated according to latest traffic ...
Passenger-to-train assignment model based on automated data
