Abstract: The regression methods and time
series models have a long history of applications to data analysis and
statistical inference dealing with randomness of the modelling systems.
Modelling techniques based on fuzzy sets, especially fuzzy rule based models
are suitable for modelling nonlinear and complex systems with imprecise
information concerning the system structure and variables. The rules can be
seen as local submodels of the system, operating in particular fuzzy
regions.
In this work we present the methods of the creating the probabilistic-fuzzy
knowledge base and the inference procedure. The rules have fuzzy antecedents
representing linguistic values of input variables and consequents in the
form of fuzzy regression equations or fuzzy time series models. This
approach can be seen as an extension of the concept of Takagi-Sugeno fuzzy
models.
Such knowledge base and inference procedure, as parts of an expert system,
are capable of supporting human decisions in control, prediction, diagnosis
and in many fields of activity.
