En simulerings- och optimeringsstudie på DSB S-tog i Köpenhamn

To improve the reglllarity of the Capenhagen commute rrain, stag, by simulation. This is achieved by simulating different time schedules in a mode! of the S-tog network, and to develop an optimization heuristic that improves the abil!ty to simulate different time schedules. Even though desirable, it would be practically impossible to try out every single time schedule combination. Consequently we have chasen to only test thase time schedules that we believe have a good passibility of being optimal. The time schedule of today has therefore been used as a base, since ir would be unreasonable that these values are completely wrong. The simulation mode! daes Ilot take in consideration extraordinary events, such as weather phenomena, and nain malfunctions. Since we have conducted a comparative analyse of the regularity for different settings of an isolated factor is the chosen method called an experimental study, but with some modificatlons. The mam purpose is rather of a problem solving nature, than explaining. Even though we only simulated a small part of the total amount of different time schedules, we achieved a result that was better than the time schedule used today. fu long as the deve!oped mode! describes the real ity good enough, the result should be useful for application on the S-tog train network.
