A note on handling multicriteria fuzzy Decision-making problems based on vague set theory

S. M. Chen (Gau and Buehrer, 1993) presented a method for handling multicriteria fuzzy decision-making problems based on vague set theory, and D. H. Hong, C. H. Choi (2000) proposed the accuracy function H to resolve some questions which can not be answered by Chen´s theory. However, Hong´s theory has still some deficiency when we handle multicriteria fuzzy decision-making problems. In this paper, we put forward a general score function G to evaluate the suitable degree of the alternatives, and we get satisfactory conclusions according to it.
