Learning together better : the structured design of learning teams
(Massachusetts Institute of Technology, 2004)
There is a great need among educators for a way to quickly assign teams in large or distance learning classrooms in a manner superior to random assignment or student self-selection. Forming teams based on knowledge of ...
Alternatives to the gradient in optimal transfer line buffer allocation
(Massachusetts Institute of Technology, 2004)
This thesis describes several directions to replace the gradient in James Schor's gradient algorithm to solve the dual problem. The alternative directions are: the variance and standard deviation of buffer levels, the ...
Degradable airline scheduling : an approach to improve operational robustness and differentiate service quality
(Massachusetts Institute of Technology, 2004)
We present a methodology for deriving robust airline schedules that are not vulnerable to disruptions caused by bad weather. In this methodology, the existing schedule is partitioned into independent sub-schedules or layers ...
Optimizing safety stock placement in general network supply chains
(Massachusetts Institute of Technology, 2004)
The amount of safety stock to hold at each stage in a supply chain is an important problem for a manufacturing company that faces uncertain demand and needs to provide a high level of service to its customers. The amount ...
Inventory deployment and market area segmentation in a two-echelon distribution network design
(Massachusetts Institute of Technology, 2004)
Most of the logistics systems involve a multi-level distribution system structure due to value added by a multi-level configuration. Interactions of these levels, i.e. echelons, should be considered while making strategic ...
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 ...
Essays on variational inequalities and competitive supply chain models
(Massachusetts Institute of Technology, 2004)
In the first part of the thesis we combine ideas from cutting plane and interior point methods to solve variational inequality problems efficiently. In particular, we introduce "smarter" cuts into two general methods for ...
Approximation algorithms for packing and scheduling problems
(Massachusetts Institute of Technology, 2004)
In this thesis we consider three combinatorial optimization problems. Specifically, we study packing and scheduling questions of relevance in several areas of operations research, including interconnection networks and ...
Multi-mission optimized re-planning in air mobility command's channel route execution
(Massachusetts Institute of Technology, 2004)
The United States Air Force's Air Mobility Command is responsible for creating a schedule and executing that schedule for a large-scale air mobility network that encompasses different mission areas. One of the mission areas ...
Portfolio strategies in supply contracts
(Massachusetts Institute of Technology, 2004)
Traditionally, industrial buyers have focused on long-term contracts for many of their purchasing needs. Recently, however, some high-tech manufacturers have started looking at more flexible contracts for non-strategic ...
