This volume contains a selection of papers presented at the second European workshop EUROCAST '91, held in Krems, Austria, in April 1991. It gives an overview of the current state of Computer Aided Systems Theory research and its relation to CAD applications in the engineering fields. CAST research requires the application of the most advanced information processing technology in software and hardware for the implementation of CAST method base systems. Engineers in the field of information and control engineering have the opportunity in CAST to present the state ofthe art in modeling tools to computer scientists. EUROCAST '91 proved that CAST research is still in an early state of development. The papers in the volume are organized into sections on systems theory and CAST methodology, modeling environments, CAST method base systems and artificial vision, and information and control systems.
