Abstract

Delphi method is one of the basic heuristic methods used in forecasting and decision making. It is based on several stages of experts’ evaluation with feedback. One of the variants is the fuzzy Delphi method, which assumes that expert’s opinion is expressed in fuzzy numbers. This article presents fuzzy Delphi method modification based on Z-numbers for expert’s opinions. It’s advantage is the fact that Z-numbers are supposed to be used to description of phenomena and processes in which we do not possess full knowledge better than fuzzy numbers. The presented version of Delphi method is used for prediction of prices of oil barrels in US Dollars.
