Grey Set Conversion and Decision Method of Intuitionistic Fuzzy Sets

摘要

To research the internal relations of fuzzy set and grey set, and to expand the application range of grey decision, this paper proposes a conversion method for grey sets of intuitionistic fuzzy sets, and studies the decision-making method based on grey relation and grey possibility degree. By integrating membership grade, non-membership grade and hesitating degree into grey membership grade decision matrix, we conform index weight by using interval grey relation method, change grey membership grade decision matrix into solution interval grey number by using index weight, and sort the solution by grey possibility degree. In the end, an example is given to illustrate the feasibility and effectiveness of this method.
