Systems of Fuzzy Reasoning and Expert Knowledge-based Fuzzy Reasoning Systems, used in Modelling Real-world Phenomena

In this paper, the concept of ‘system of fuzzy reasoning’ is presented. It is the fi rsttemptation to expand ideas presented in [1] concerning ‘human intelligence’ linguisticvariable and [2] concerning ‘truth value of fuzzy reasoning’ in the framework of thehuman intelligence linguistic variable. In ‘systems of fuzzy reasoning’, besides the‘human intelligence’ linguistic variable also other linguistic variables are also used.An expert knowledge-based system of fuzzy reasoning describing the dynamics of areal-world phenomenon is presented.
