Selected Practice-Related Projects

ALPHABOT: a flexible manufacturing system
ALPHABOT is a physical model of a flexible manufacturing system. It was developed to illustrate the impact of optimization in complex manufacturing systems. Together with H. Gröflin, I initiated and led the project. For more information, see my ALPHABOT website.
DDSS-ESSA / Dicodess: Distributed decision support systems
I was a developer of a distributed decision support system (named DDSS-ESSA and DICODESS) used for food security by the Swiss government, see also the article Wie sicher ist die Ernährungssicherung? - Agrarforschung Schweiz (in German).
A course scheduling tool
I developed a tool that automatically schedules the 60 courses of the Swiss Joint Master of Science in Computer Science study program (jointly offered by the Universities of Bern, Fribourg and Neuchâtel)
A tournament scheduling tool
I developed a tool that automatically schedules a floorball tournament with nearly 300 matches.
