Welcome to the
BISC Program
Summary
of principal contributions
- Development of a
frequency-domain based theory of time-varying networks, 1949.
- Extension of
Wiener's theory of prediction, with J.R. Ragazzini,
1950.
- Development of the
z-transform approach, with J.R. Ragazzini,
1952.
- Development of a
theory of nonlinear filters, 1953.
- Formulation of
the problem of system identification, 1956.
- Initiation of the
state-space approach to the analysis of linear systems, with C.A. Desoer, 1963.
- Initiation of the
theory of fuzzy sets, 1965.
- Development of a
theory of decision-making in a fuzzy environment, with R.E. Bellman,
1970.
- Introduction of
the concepts of a linguistic variable and fuzzy
if-then rules, 1973. This work laid the foundation for fuzzy
logic control and most of the current applications of fuzzy logic.
- Development of
possibility theory, 1978.
- Development of
PRUF - a meaning representation language for natural languages, 1978.
- Development of a
theory of approximate reasoning, 1979.
- Development of a
theory of ususality and commonsense reasoning,
1985.
- Development of
test-score semantics for natural languages, 1986.
- Development of
the concept of a generalized constraint, 1986.
- Development of
dispositional logic, 1988.
- Initiation of the
calculii of fuzzy rules, fuzzy graphs and
fuzzy probabilities, 1991.
- Development of
Soft Computing, 1991.
- Development of
Computing with Words, 1996.
- Development of a
theory of fuzzy information granulation, 1997.
- Development of a
Computational Theory of Perceptions, 1998.
- Development of Precisiated Natural Language, 2000.
- Development of a
perception-based theory of probabilistic reasoning, 2001.
- Development of
the concept of generalized definability, 2001.
