George Jiri Klir (born 1932
Prague, Czechoslovakia) is a Czech-American computer scientistand professor of systems sciencesat the Center for Intelligent Systems at the State University of New York at Binghamton, New York.
George Klir was born in 1932 in
Prague, Czechoslovakia. In 1957 he received a M.S.degree in Electrical engineeringat the Czech Technical University in Prague. In the early 1960s he taught at the Institute of Computer Research in Prague. In 1964 he received a doctorate in Computer sciencefrom the Czechoslovak Academy of Sciences.
In the 1960s Klir went to
Iraqto teach at the Baghdad Universityfor two years. At the end he managed to immigrate to the U.S. [http://www.binghamton.edu/watson/level3/WatRevSpr07.pdf. "George Klir, pioneer in systems science, ready to retire"] , Watsons Review, Spring 2007.] . He started teaching computer science at UCLA and at the Fairleigh Dickinson University. In 1969 he came to State University of New York at Binghamton, now called Binghamton University, where he later became here professor of Systems science. One year 1982–1983 he stayed as a fellow in Dutch Netherlands Institute for Advanced Studyin the Humanities and Social Sciences" (NIAS), where he completed the manuscript of his book "Architecture of Systems Problem Solving". In 2007 he is retiring after 37 years at the University. On of his doctoral students was Richard Sternberg[http://www.rsternberg.net/CV.htm "Richard Sternberg Curriculum vitae (partial)"] ]
Since 1974 Klir is editor of the "
International Journal of General Systems", and the "International Book Series on Systems Science and Systems Engineering" since 1985. From 1980 to 1984 George Klir was the first president of the International Federation for Systems Research(IFSR). In the year 1981–1982 he was is also president of Society for General Systems Research, now International Society for the Systems Sciences. He was further president of the North American Fuzzy Information Processing Society from 1988 to 1991 and the International Fuzzy Systems Association (IFSA) from 1993 to 1995.
Klir received numerous awards and honors, including 5 honorary doctoral degrees, the Gold Medal of Bernard Bolzano, Lotfi A. Zadeh Best Paper Award, the Kaufmann's Gold Medal, SUNY Chancellor's Award for Excellence in Research and IFSA Award for Outstanding Achievement. [ [http://www.ssie.binghamton.edu/faculty_klir.html "George Klir bibliography"] , Thomas J. Watson school, 2007.] In 2007 he has been awarded the Fuzzy Systems Pioneer Award of the
IEEEComputational Intelligence Society (CIS).
George Klir is known for path-breaking research over almost four decades. His earlier work was in the areas of
systems modelingand simulation, logic design, computer architecture, and discrete mathematics. More current research since the 1990s include the areas of intelligent systems, generalized information theory, fuzzy set theoryand fuzzy logic, theory of generalized measures, and soft computing.
General systems theory
Klir's research in
general systems theoryformed one of the foundations of systems scienceas an independent discipline and systems thinkingas a process necessary across diverse domains — from biological to manufacturing. This is why he is called “the father of systems science” by many. [ [http://inside.binghamton.edu/news/newspage.cgi?issue=2005oct20&id=16 Inside Binghamton University ] ]
Systems science, according to Klir, is the study of
knowledgestructures and is a bridge between natural languageand mathematics. As with applied mathematics, systems science is not confined to one field. Klir started thinking about this when he was still studying electrical engineering. He noted that sophisticated methods for analyzing electrical circuits led to a new mathematical theory. He began to realize that there were profound similarities between phenomena investigated by diverse disciplines of science or engineering that allow us to transfer knowledge from one discipline to another. The boundaries between disciplines started to lose some of their significance in my mind.
In the early 1960s Klir was teaching about computers in a wide range of audiences, which led him to work with biologists, physicians, economists, linguists, psychologists and even musicologists. These collaborations strengthened his belief that “systems and problems were not completely different from one discipline to another. According to Klir "Each system shares fundamental concepts such as information, control, organization, structure, invariance and change, learning and pattern recognition".
Founding of the IFSR
In 1980 the
International Federation for Systems Researchwas founded to interlink groups ofsystem thinkers around the world and to try to find answers to some of the pressing problems ofthe world. The key persons beside George J. Klir were Robert Trappland Gerard de Zeeuw, and they became the first officers of the IFSR. [http://www.ifsr.org/Flyer_emcsr_20060115.pdf "International Federation For Systems Research"] , flyer 15 January 2006.]
Klir's first contribution to the field of
fuzzy logiccame from his work with the geologist Robert Demicco. Together they applied fuzzy theory to problems in Earth science, which resulted in the book "Fuzzy Logic in Geology". Klir later wrote a history of fuzzy logic. Lotfi Zadeh, the father of fuzzy logic was ridiculed when Zadeh introduced his theories. "It is a wonderful example of a grand paradigm shift in mathematics that affects everything," he said.
Klir contribution to generalized theories of
uncertainty, combine fuzzy, probabilistic, intervals, and other types of uncertainty, to the design and analysis of different measures of uncertainty, and in many other areas. Klir sees interval computations is an important tool for fuzzy research. He has been advocating the need to combine interval computations and corresponding fuzzy computations with constraints. He himself contributed to the development of the corresponding constraint fuzzy arithmetic and fuzzy arithmetic with requisite constraints.

Generalized Information Theory
The term "Generalized Information Theory" (GIT) was introduced by George Klir in the early 1990s in his so called article in the "Fuzzy Sets and Systems" journal. This concept was meant as a research program whose objective was to develop a broader treatment of uncertainty-based information, not restricted to the classical notions of uncertainty. [1991, George Klir, "Generalized information theory", Fuzzy Sets and Systems, Vol 40 nr. 1, pp. 127–142.] The basic tenet of GIT is that uncertainty can be formalized in many different ways, each based on some specific assumptions. To develop a fully operational theory for some conceived type of uncertainty, we need to address issues at four levels: [ [http://www.carleton-scientific.com/isipta/PDF/024.pdf. An Update on Generalized Information Theory] , George Klir, 2000 ]
*LEVEL 1 – we need to find an appropriate mathematical representation of the conceived type of uncertainty
*LEVEL 2 – we need to develop a calculus by which this type of uncertainty can be properly manipulated
*LEVEL 3 – we need to find a meaningful way of measuring the amount of relevant uncertainty in any situation formalizable in the theory
*LEVEL 4 – we need to develop methodological aspects of the theoryThis Generalizes Information Theory is according to Klir, an outgrowth of two classical
uncertaintytheories. The older one, which is also simpler and more fundamental, is based on the notion of possibility.The newer one, which has been considerably more visible, is based on the notion of probability.
