'''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.

== Education ==
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 has been working in the Centre of Biomedical Engineering at the Bulgarian Academy of Sciences, currently being the head of the "Biomedical Informatics" department.

== Research==
==== Generalized nets ====

In 1983 Atanassov introduced the object "[[Generalized net]]" and investigated its basic properties, as well as some of its [[applications of generalized nets|applications]] in artificial intelligence, systems theory, medicine, economics, transportation, chemical industry and others.

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 [[Operators over generalized nets|operator]], topological and logical aspects he has introduced have no analogue in Petri nets theory.

==== Intuitionistic fuzzy sets ====

The other fundamental field of research interest for Atanassov are [[Intuitionistic fuzzy sets]], which are an extension of the concept of [[Fuzzy sets]] as defined by [[Lotfi Zadeh]]. Atanassov researches the properties of IFS and has also initiated the applications of IFS in expert systems, systems theory, decision making and other scientific areas.

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 over intuitionistic fuzzy sets|operators]] on modal, topological, level, which Atanassov introduced and researched.

== Bibliography ==
Krassimir Atanassov has published about 370 papers in journals, 140 conference reports, 20 monographs.
