A Grey Incidence Based Group Decision-Making Approach and Its Application

We define the group measure matrix of alternative scheme and ideal based on relevant factor sequence system characteristic behavior sequence. Furthermore, information distances decision makers criteria are defined, respectively. According to distance, we obtain each scheme’s grey incidence degree for ranking. Finally, use an example verify rationality model compare it with other classic methods, such as TOPSIS, VIKOR, MULTI-MOORA. Compared previous analysis model, proposed can make full decision-maker dimension dimension. The avoid high-dimensional loss. results show that method has superiority in measuring decision-making standard information.
