Decision Support for Scheduling: Models, Methods and Validation

In this project we have developed column generation methods for a kind of scheduling in telecommunication (uplink scheduling in SC-FDMA) and for solving transportation problems with both fixed and linear costs. We have also developed a meta-heuristic search method for column-oriented models. The method is of a large neighbourhood search type where the repair step is to generate a column.

This work has resulted in Yixin Zhao's doctoral thesis: On the Intergration of Heuristics with Column-Oriented Models for Discrete Optimization.


This was a project within the Research school in interdisciplinary mathematics. The following people were involved: PhD student Yixin Zhao, Professor Torbjörn Larsson (main supervisor), Senior lecturer Elina Rönnberg (assistant supervisor). All at the Division of Applied Mathematics (TIMA), Department of Mathematics, Linköping University. The telecommunication part of the project is carried out in collaboration with Professor Di Yuan, Communications and Transport Systems, Department of Science and Technology, Linköping University.
