In order to evaluate the green packaging scheme scientifically and reasonably, a green packaging evaluation method integrating probabilistic linguistic and QUALIFLEX in the social network environment is proposed. Firstly, the evaluation index system of green packaging is determined and the evaluation information of decision-making experts is expressed by using probabilistic linguistic term sets (PLTS). Then the weights of decision-making experts and criteria are calculated by using the trust relationship network among decision-making experts and decision-making expert-criterion preference matrix respectively, and finally, the outranking relationship of alternative green packaging schemes is determined by QUALIFLEX method. The effectiveness and rationality of the proposed method are verified by comparing with other methods.
