Özet

This paper deals with the problem of defuzzification of a fuzzy number on the basis of decompositional representation that takes into account the strategy of making decisions by a decision-maker (DM). Some advantages of this approach are shown and a method is proposed that increases the level of preciseness of the averaged representative of a fuzzy number with the help of changing weight coefficients of level sets.
