| description | The invention relates to an interval intuitionistic fuzzy supplier selection method based on grey relational degree, and belongs to the technical field of multi-attribute decision making. According to the technical scheme, the method comprises the steps of firstly, establishing an interval intuition fuzzy evaluation matrix according to an evaluation value of an expert; secondly, respectively calculating a comprehensive evaluation value of each supplier by utilizing an interval intuitionistic fuzzy weighted average operator (IIFWA); then, improving a score function by calculating the grey correlation degree of the expert evaluation value and the subjective preference value, wherein subjective preference factors of experts are considered in the new score function; and finally, calculating scores of the suppliers by using an improved score function, sorting the scores and selecting an optimal supplier. The method has the advantages that the grey correlation degree and the interval intuition fuzzy are combined, t |
