This paper presents a simple and useful decision method for making estimates in uncertain and dynamic environments. We extend traditionally triangular fuzzy numbers to pillared and triangular fuzzy numbers formats that are defined by X-Y-Z axes. The α-cut and the defuzzy method of the proposed fuzzy number type are also defined. Finally, a numerical example based on a multiple attribute decision making method is used to illustrate the proposed method.
