LIT Cyber-Physical Systems Lab.

Welcome to the LIT | CPS Lab!

More with less — how do we master the increasing complexity of production systems?

Industry faces major challenges as product lifecycles shorten, product variability increases, and global markets become more volatile. To remain competitive, production facilities and equipment must be adaptable to respond quickly and efficiently to these changes.

A key success factor in achieving these goals is the control and automation infrastructure. New distributed architectures are a possible approach to address these requirements. New interaction and communication patterns as well as new ways of programming automation systems consisting of networked control units are required.

Mastering variability and complexity in cyber-physical production systems also requires new software engineering methods and tools, particularly for variability modeling and product configuration as well as to support maintenance and evolution.

Lisa Sonnleithner and Kevin Feichtinger successfully completed the dissertation colloquium

On September 29, the dissertation colloquium of the Computer Science Department of JKU took place. The candidates present their field of research, their research methodology, their results (publications) and the final steps to the written dissertation. Afterwards, the candidates face questions from the faculty, similar to the actual dissertation defense. This time, our PhD candidates Lisa Sonnleithner and Kevin Feichtinger participated in the colloquium. We are excited to announce that they passed the final milestone of the curriculum with flying colors and now enter the final phase of their respective dissertations.

Summer team event: LIT CPS team swaps office for lake

Yesterday we swapped the office for a day at the Ausee. Instead of meetings and video conferences, relaxation and fun were on the agenda. In the evening we went to the Rooftop7 Bar in Linz where we ended the day with excellent food and a drink or two.
