Abstract: Sustainable supplier selection plays an important role in the construction of sustainable supply chain.With respect to sustainable supplier selection under multi-products purchases,a novel evaluation index system of supplier selection was proposed based on economic performance,environmental performance and social performance of sustainable supplier.Then the two-stage supplier selection model was proposed.In the first phrase,the candidate suppliers meeting the basic requirements of environmental performance and social performance was selected.In the second phrase,the different decision-making methods were proposed based on the requirements of core enterprise for the number of suppliers through the evaluation of qualified candidate suppliers' economic performance.In the model,Possibility Distribution-Hesitant Fuzzy Linguistic Term Set (PD-HFLTS) was utilized to characterize the evaluation information with the advantage of more information contained and more accurate calculation,and then the group consensus checking and adjusting algorithm was given to overcome the the effect of outliers.Aiming at the problem that it was not easy for experts to give the preference information of pairwise comparison with a large number of the indices,the Best Worst Method (BWM) based on PD-HFLTS was proposed to solve the problem,and then a novel consistency checking and adjusting algorithm was proposed.The feasibility and effectivity of the model was illustrated by the example of sustainable supplier selection of an automobile seat manufacturer with four kinds of raw materials purchases.

Key words: sustainable supplier selection, possibility distribution-hesitant fuzzy linguistic term set, best worst method, group consensus
