Yanling Li, Qifei Yan, Jian-Wei Wu · 2017
Aiming at the group decision making problem of multi-person and multi-decision matrix, a multi-attribute group decision making method based on evidence theory has been proposed. In this method, firstly, the expert is regard as source of evidence to construct mass function of scheme, use expert weight coefficient to weight evidence, and to get the group decision making matrix. Secondly, according to the group decision making matrix, the attribute was regard as sources of evidence, to weight the evidence by measuring the dispersion degree of attribute based on grey correlation degree, and to obtain the belief function of each scheme based on weighted evidence composition principle. Lastly all the schemes will be ordered based on the value of belief function. By analysis a numerical example, the effectiveness of the method in this paper is verified.
