Difference between Fuzzy Delphi Method and Delphi Method

The Delphi method is a reasoning method based on expert opinion, which reaches a conclusion through repeated discussion, modification and reaching *** knowledge of the same problem by multiple experts. The fuzzy Delphi method, on the other hand, introduces the theory of fuzzy mathematics on the basis of the traditional Delphi method, which allows experts to give opinions with a higher degree of uncertainty and to deal with problems that are difficult to quantify or are subjective in nature.

Thus, compared to the traditional Delphi method, the fuzzy Delphi method is more advantageous when dealing with certain fields that involve more fuzzy properties or are difficult to describe accurately.
