Krassimir Atanassov

Krassimir Todorov Atanassov (23 March 1954, Burgas, Bulgaria) is a Bulgarian mathematician. He is best known for launching the concepts of Generalized nets and Intuitionistic fuzzy sets, which are extensions of the concepts of Petri nets and Fuzzy sets, respectively. Atanassov is also known for his research in the area of number theory.

Biography

Krassimir Atanassov graduated mathematics in the Sofia University, Sofia, in 1978, and defended his PhD in 1986. He became Doctor of Technical (computer) Sciences in 1997, with a doctor thesis on Generalized nets, and three years later defended a second degree - Doctor of Mathematical Sciences, with a thesis in the other field of his scientific interest - Intuitionistic fuzzy sets.

Honorary Associate of the University of Technology, Sydney, since 1995.Member of the Union of Bulgarian Mathematicians, since 1979, and of the American Mathematical Society, since 1989.Since 1995 he works in the Centre of Biomedical Engineering at the Bulgarian Academy of Sciences, being a vice director and scientific secretary.

Research

Generalized nets

In 1983 Atanassov introduced the object "Generalized Net" and investigated its basic properties, as well as some of its applications in artificial intelligence, systems theory, medicine, economics, transportation, chemical industry and others.He was the engine of the theoretical research on the area of Generalized nets, and promoted much of the applied research. He has defined a lot of operations and relations over generalized nets, part of which have analogues in the theory of ordinary Petri nets. However, the topological and logical operators he has introduced have no analogue in Petri nets theory.

Intuitionistic fuzzy sets

The other fundamental field of research interest for Atanassov are Fuzzy sets, defined by Lotfi Zadeh, which he significantly extended by launching the concept of "Intuitionistic Fuzzy Sets" and investigated their basis properties. He has also initiated the applications of Intuitionistic fuzzy sets in expert systems, systems theory, decision making and others. He has studied and defined a lot of operations and relations over intuitionistic fuzzy sets, part of which have analogues in the theory of fuzzy sets. Without analogues in traditional fuzzy set theory are the operators on modal, topological, level, which Atanassov introduced and researched.
