Quantitative analysis with linguistic values

Abstract The concept of quantitative analysis with linguistic values is set out and discussed. An APL-implemented auxiliary language is presented which makes such analysis operational with regard to humanistic systems where the variables cannot easily be numerically measured. Special emphasis is placed on linguistic approximation which is implemented by an APL-function of 19 statements with a range of approximately 10 10 linguistic values. Examples of the linguistic input-linguistic output characteristics of the language are shown.
