Welcome to the BISC Program


 


Summary of principal contributions

  1. Development of a frequency-domain based theory of time-varying networks, 1949.
  2. Extension of Wiener's theory of prediction, with J.R. Ragazzini, 1950.
  3. Development of the z-transform approach, with J.R. Ragazzini, 1952.
  4. Development of a theory of nonlinear filters, 1953.
  5. Formulation of the problem of system identification, 1956.
  6. Initiation of the state-space approach to the analysis of linear systems, with C.A. Desoer, 1963.
  7. Initiation of the theory of fuzzy sets, 1965.
  8. Development of a theory of decision-making in a fuzzy environment, with R.E. Bellman, 1970.
  9. 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.
  10. Development of possibility theory, 1978.
  11. Development of PRUF - a meaning representation language for natural languages, 1978.

  13. Development of a theory of ususality and commonsense reasoning, 1985.
  14. Development of test-score semantics for natural languages, 1986.
  15. Development of the concept of a generalized constraint, 1986.
  16. Development of dispositional logic, 1988.
  17. Initiation of the calculii of fuzzy rules, fuzzy graphs and fuzzy probabilities, 1991.
  18. Development of Soft Computing, 1991.
  19. Development of Computing with Words, 1996.
  20. Development of a theory of fuzzy information granulation, 1997.
  21. Development of a Computational Theory of Perceptions, 1998.
  22. Development of Precisiated Natural Language, 2000.
  23. Development of a perception-based theory of probabilistic reasoning, 2001.
  24. Development of the concept of generalized definability, 2001.
