On could argue that "fuzzy logic" is used in almost every model system
dynamicists build. Repeatedly, thinking about aggregates "smoothes out"
influences that for an individual would be shaped like a step, exactly the
way the membership function in a fuzzy set is a smothed out version of the
membership function in a discrete set. And the teaching of weighting
functions for aggregate if-thens has been going on in the field probably
longer than fuzy set logic has been popular.
But I dont know of a specific applications of fuzzy logic to accomplish
some end in a system dynamics model that required the sophisticated
accomplishments of the fuzzy logic folk.
