Intro

I started my PhD in September 2007 here at Informatics/TUM in the group of Dr. Martin Sachenbacher. My research interests are

  • model-based development and operation of technical systems
  • constraint-based diagnosis and planning
  • model-based reasoning, specifically model-based diagnosis
  • constraint optimization
  • probabilistic reasoning

On a more general scope I'm interested in the elements that constitute intelligent behavior and problem solving. I find it deeply fascinating to view and analyze tasks such as bringing a product design to live as a real product as computational problems.

Prior to my PhD studies I made my diploma in Computer Science at the University of Passau. In my diploma thesis, "Content-Based Image Retrieval: Review and Benchmarking", I analyzed and benchmarked a number of content-based image retrieval systems.   

Research

In my current research I focus on the model-based operation of manufacturing plants. Future factories are envisioned as highly automated facilities that can help human workers not only with mundane, repetitive tasks, but also support them by, e.g., automatically generating manufacturing schedules for customized products. Typically, automated scheduling is computationally intensive and therefore is done "off-line", e.g. during the night. The next day schedules can be executed to manufacture the products. However, while executing, current sensor data might indicate faults in this complex environment. The question arises, how this affects the single products currently being processed. In my thesis, I address this question as the problem of plan assessment: computing the probability that a product's manufacturing plan will successfully create the product, given sparse on-line sensor information and a probabilistic model of factory stations and products.
