Fuzzy reasoning in pseudo-physical logics

Abstract

A new approach is described to modelling of human reasoning about objects acting in a real physical environment. Special pseudo-physical logics - temporal, locative, causal, etc. - are used for description of environment properties and related regularities. The basic idea lies in assigning values of linguistic variables of one pseudo-physical logic to these of another that enables one to define these values through values of other linguistic variables without constructing membership function. This approach is illustrated by determination of the values of linguistic variable 'distance' through those of linguistic variable 'size'. © 1987.
