#### **Vil ´em Nov ´ak**

Vilem Nov ´ ak is a senior researcher and full professor at the Institute of Research and ´ Applications of Fuzzy Modeling (University of Ostrava). He is the founder and former director of this institute. His research interests include mathematical fuzzy logic and its applications. He is the author of several formal theories that served as source material for establishing the theory of fuzzy natural logic. His theoretical results led to the development of an original method of fuzzy/linguistic control of technological processes based on expert knowledge, which also has practical applications. He also developed several non-statistical methods for the processing of time series. He is the author and co-author of more than 300 scientific papers and 5 scientific monographs. His h-index is 29 (WOS).
