(2) Dimensioning and resource requirements: Turnround time as calculation parameter; Dimensioning of rolling stock need; Dimensioning of staff need. (3) Vehicle operating strategies and concepts: Rolling stock strategies; Train composition strategies; Vehicle concepts; Vehicle design; Case studies. (4) Traction technology and energy supply: Technical requirements for vehicles; Vehicle body; Running gear; Train composition; Train resistance; Traction technologies; Energy supply. (5) Travel time, stop time and reserves: Overview on the calculation process; Identification of maximum allowed speed; Calculation of running time; Calculation of stop time; Quantifying the reserves. (6) Introduction to capacity analysis: Netwoork design / Capacity / Path allocation management; Definition and measurement of capacity; Infrastructure occupation; Network management and optimiziation of capacity use; Tools and forms of representation; Path allocation process. (7) Capacity of lines, nodes and local networks: Process of network capacity check; Principles and methods; Estimation and experience based values; Analytical methods; Simulations.

AbstractThis course is a mixture between a seminar primarily for PhD and postdoc students and a colloquium involving invited speakers. It consists of presentations and subsequent discussions in the area of modeling and governing complex socio-economic systems, and managing risks and crises. Students and other guests are welcome.
ObjectiveParticipants should learn to get an overview of the state of the art in the field, to present it in a well understandable way to an interdisciplinary scientific audience, to develop novel mathematical models and approaches for open problems, to analyze them with computers or other means, and to defend their results in response to critical questions. In essence, participants should improve their scientific skills and learn to work scientifically on an internationally competitive level.
