In the selection of green packaging schemes, in view of the fact of the number of criteria obviously exceeding the number of schemes, and the complexity in the trust relationship among decision-making experts and the preference relationship for criteria in group decision-making under the social network environment, a green packaging scheme evaluation method integrating social network and priority relationship is proposed. Firstly, the evaluation index of green packaging schemes is determined, and the evaluation information of decision-making experts is expressed by using the probabilistic linguistic term set. Then, the weight of decision-making experts is calculated by using social relationship network analysis, and the weight of criteria is calculated by using preference relationship network analysis and probability formula. QUALIFLEX method is used to determine the priority relationship of alternative green packaging schemes. The validity and rationality of the proposed method are verified by comparing with other methods.
