Abstract [en]

In a complex system such as the Norwegian railway network, there are much that can affect a trains punctuality. The undertakers strive to achieve higher and higher punctuality, while the infrastructure owner, Jernbaneverket, strive for minimal downtime on the railway network. There is collected much data for analysis about the trains run and the infrastructure, in order to achieve higher punctuality and less downtime. The users are able to track down the source of delays and find possible improvements on the infrastructure, by analyzing and comparing the different data sets collected. There are many users across both different companies and internal divisions in a company that need to cooperate, due to the size and complexity of a railway network. The different users have different needs when studying the data sets. A area director have the need to see the big picture over time, while a segment director wants to see every detail within its segment. In this thesis we demonstrate a system that is aware of the different stakeholders requirements when presenting data. The system also takes into consideration the stakeholders need for analyzing different types of data, and comparing these. Finally, we conclude how users should be defined within a domain in order to be aggregated over.
