- Abstract
- Purpose: The purpose of this thesis is to develop a simulation model that represents the S-train network. The model will then be analysed in order to improve the regularity. We will then present a locally optimized proposal on the placement of the buffer time for every train line. Delimitation: This report intends only to analyse a ”normal day” during rush hour. We will ignore unexpected course of events, e.g. train breakdowns, accidents, electricity errors and signal errors. Method: This thesis can be defined as a case study with an explanatory examination. We have chosen to follow Banks’ (1998) twelve step guide to conduct a simulation project.
Conclusions: All results indicate that our model is a good representation of the real...

Conclusions: All results indicate that our model is a good representation of the real situation. We therefore consider our model to be validated. From the simulation results we have come to the conclusion, that it is very important for the trains to arrive to the central part as planned, in order to prevent the trains from blocking each other. This is because the blockings cause the largest delays in the S-train network. It is also important to avoid regularity violations because they are often hard to get rid off and create regularity violations all the way to the end station. (Less)
