An Analysis of Fuzzy Models and a Discussion of their Limitations

  • R. M. Tong

Abstract

This paper considers the value of fuzzy models as descriptions of technological processes. It analyses the effect of a priori assumptions on the quality of the model and introduces a systematic technique for constructing fuzzy models from normal operating records. Finally, the paper contains three case studies which serve as examples for a discussion of the limitations of this approach to process modelling.
