FUZZY SET SIMULATION MODELS IN A SYSTEMS DYNAMICS PERSPECTIVE

This paper introduces and discusses the concept of verbally formulated simulation models. Such models can operate with linguistic values as “high,” “rather high,” “low” and “not low,” etc. as inputs. The output will be similarly verbally formulated. The simulation procedure is based on a fuzzy set‐theoretic semantic model of a fragment of the English language, which converts verbal expressions into numerical quantities. The paper applies one particular semantical model in a simulation example.
