On the Issue of Comparisons with Reference Fuzzy Numbers - a Graphical Method to Guide the Choice of a Suitable Method in Managerial Decision-making
Original language description
This paper proposes a mathematical method for the analysis ofthe be- havior of similarity measures of fuzzy numbers in the task of comparing a fuzzy output ofa mathematical model with a reference fuzzy number. It is based on the visualisation ofthe set ofall fuzzy numbers similar with the reference fuzzy num- ber. This approach provides the user with the information concerning the whole set of objects that are considered equally similar to the reference object on the given level of similarity. This novel approach allows the used to see howcompact or diverse the set of "equally similar" objects is. It thus allows the user to see how reasonable it might be to rely on the given similarity measure of fuzzy numbers in the given application problem. The proposed method is intended for laymen users of fuzzy model, while providing valuable insights for the designers of these models as well. The selection of appropriate similarity measure can be benefi cial in a wide set of practical problems using models that provide fuzzy outputs, ranging from evaluation tasks through the ordering of alternatives (managerial decision-making) to fuzzy optimization.
