Abstract:This paper shows:1) It is wrong to use the method of taking the bigger or smaller to decide the evaluating vectors in the mode1 M(∨,∧) of Fuzzy synthefical evaluation. 2) The definition of union (intersection) of the Fuzzy sets is worth discussing.
Keywords:fuzzy subordination degree  synthetically evaluation  M(∨  ∧) model
