Dear all, this is a reminder for the next UnRAVeL survey lecture that takes place this *Thursday, June 17 at 4:30pm*.*Nils Nießen *will talk about *Optimised Maintenance of Railway Infrastructure*. Following the talk, UnRAVeL PhD student *Stephan Zieger* will give an informal summary of their doctoral studies within UnRAVeL.
*Abstract* The effect of maintenance and renewal funds on the quality of railway infrastructure is difficult to quantify. In order to establish a direct link, a model is presented to illustrate the cause-effect relationship, which describes the influence of the resources used on the infrastructure quality and vice versa. The model was applied for the infrastructure of DB Netz AG. The infrastructure under consideration is divided into the object groups bridges, tracks, points, signal boxes and level crossings. For these object groups, algorithms were created that map the cause-effect relationship by means of forecast approaches (bridges and tracks) and risk approaches (points, signal boxes and level crossings). The presentation describes the mapping of the cause-effect relationship using the example of the forecast model for the development of the condition of bridges.

Each lecture is delivered by one of the researchers involved in UnRAVeL. The main aim is to provide doctoral researchers as well as master students a broad overview of the subjects of UnRAVeL. This year, 12 UnRAVeL professors will answer the following questions, based on one of their recent scientific results: * How did you get to this result? * How did you come up with certain key ideas? * How did you cope with obstacles on the way? Which ideas you had did not work out? Following these talks, PhD students will give an informal summary of their doctoral studies within UnRAVeL. All interested doctoral researchers and master students are invited to attend the UnRAVeL lecture series 2021 and engage in discussions with researchers and doctoral students.

All events take place on *Thursdays from 16:30 to 18:00 on Zoom* https://rwth.zoom.us/j/96043715437?pwd=U0dRczkyQjRCY21abW13TDNmUHlhUT09 * 10/06/2021 Britta Peis: Sensitivity Analysis for Submodular Function Optimization with Applications in Algorithmic Game Theory * 17/06/2021 Nils Nießen: Optimised Maintenance of Railway Infrastructure * 24/06/2021 Gerhard Lakemeyer: Uncertainty in Robotics * 01/07/2021 Joost-Pieter Katoen: The Surprises of Probabilistic Termination * 08/07/2021 Christina Büsing: Robust Minimum Cost Flow Problem Under Consistent Flow Constraints * 15/07/2021 Gerhard Woeginger: Bilevel optimization /(to be rescheduled)/ * 22/07/2021 Ulrike Meyer: Malware Detection We are looking forward to seeing you at the lectures.
