Model-Based Diagnosis of Hybrid Systems Using Satisfiability Modulo Theory

Alexander Diedrich, Alexander Maier, Oliver Niggemann
2019 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
In this paper we present a novel model-based diagnosis approach for automatically diagnosing hybrid systems.  ...  With this, we create a static situation for the diagnosis algorithm and decouple modelling and diagnosis.

Knowledge-based cost-benefit analysis of robotics for SME-like manufacturing [article]

Thomas Dietz, Universität Stuttgart, Universität Stuttgart
2019
These models and the meta-information required for their usage are collected in a knowledge base.  ...  The input for the cost-benefit assessment is a description of the current planning status in AutomationML. This information is matched to the information in the knowledge base through reasoning.  ...  Hence, resources have limited cardinality and limited capacity and therefore control the speed with which activities are processed in the model.  ...
