(Research Information Ltd, 2019) Guo, Sandang; Li, Ye; Dong, Fenyi; Li, Bingjun; Yang, Yingjie
According to the characteristics of three-parameter interval grey number and the advantages of grey target, a multi-attribute grey target decision-making method is built. First, the "kernel" of the three-parameter interval grey number based on the most probability' is defined, and the upper bound degree of greyness and the lower bound degree of greyness are separately defined for the asymmetry on the two sides, then the distance measure formula affected by the risk attitude of the decision maker is given. Considering the proximity of schemes to the optimal vector and the worst vector, the comprehensive off-target distances and their space projection on the line connecting the point of the positive bull's eye and the negative bull's eye are obtained, and the ranking of the schemes is ultimately determined. Finally, an example validates the rationality and effectiveness of the method, which may provide a new way of thinking in terms of research on grey decision-making theory and application.
