Optimering och tidtabelläggning: slutrapportering av förstudie

Per Olov Lindberg
Martin Aronsson

The purpose of this pilot study has been to assess the potential for developing an optimization tool for time-tabling of railway traffic. The study is based on a 20-year-old paper that the authors of the pilot study co-authored. The subsequent papers published in this field of research provide a basis for considering the further development of the original model architecture. A crucial component in this is the rapid capacity improvement of computer capacity. A second issue has been to consider the possibilities to speed up the solution to the large and complex algorithms used for identifying an optimal solution.

The mimeo demonstrates that the preconditions for improving the performance of the original model are very good. In three background papers, different dimensions of this potential are addressed. The description concludes by suggesting the design of a further test of the method on a shorter section of the national grid. Importantly, the test would be realized in parallel with the annual development of a new time-table for the coming year.
