Evaluation and implementation of mathematical models for train diagnostics (aw)

The company Bombardier
Bombardier Inc, with headquarters in Canada is a world leading manufacturer of innovative transport solutions, from regional aircrafts and business jets to railway equipment. Turnover was for the financial year 2006, $14.7 billion US and stocks is sold on the market in Toronto (BBD). News and information is available at www.bombardier.com.
Bombardier Transportation has its global head quarter in Berlin and are represented in over 60 countries. The company group has installed totally 97,000 vehicles worldwide. The company group offers the most complete product portfolio and is a recognised world leading supplier to the global train sector.
Bombardier Transportation in Sweden employs 1500 persons at sites in Västerås, Stockholm, Hässleholm, Nässjö and Göteborg and offers a complete set of products for train and railway on the swedish market. Sweden is a center of technology for development of vehicles, train signals, driving line and control for the global market.

A modern train includes central computers with data buses and control logics, hundreds of computers in sub-systems controlling doors, passenger comfort system, motors and breaks. The systems monitoring system is continuously sending data about the train behaviour and condition. Under development at Bombardier is a so called comfort computer that on-line can report train health.

The MSc degree work is to implement a mathematical model of the train into the comfort computer. The model is used to predict train behaviour and to solve tasks like detection of abnormal behaviour. Bayesian networks can be one of the methods applied to model the train. The task will mainly be solved in C#, in a combined Windows and Linux-environment. The model is tested on an advanced train simulator for train driving systems in Västerås. In addition to the work on the mathematical train model is a report on the known methods in the field of application.

The objective is to seek out what kind of methods are suited for modelling a train to be used as monitoring of train health.

Applicants for the degree work
Required is that the Master student got an interest of mathematical modelling and documented programming skills. Curiosity, communcation skills and ability to solve tasks methodically are also highly valued. Please leave your application with attached excerpt of completed courses in the post box of Christer Karlsson at The Department of Public Technology, Mälardalen University.
