INSTITUTE OF INFORMATION TECHNOLOGIES - BAS

Department: Intelligent Systems
Head of Department: Academician Vassil Stoyanov Sgurev

Current research of the IS department is concentrated on developing modern methods for analysis and sythesis of complex intelligent information and control systems based at dynamic ontologies, multiagent systems, softsensing. Novel results are obtained in the domain of hybrid dynamic systems, behavior and dynamics of swarms, model predictive control based on intelligent agents. The department also has a traditional interest and results in developing formal logical and probabilistic methods for research of dynamically changing systems with network structures.
Applied department elaborations are oriented towards information technologies for intelligent diagnostics and monitoring of industrial systems and ontologically based e-learning.
