Zusammenfassung:	The invention provides a supplier selection method based on a Pictgomery fuzzy set and VIKOR, and belongs to the technical field of supplier evaluation and selection. The supplier selection method based on the Pictgomery fuzzy set and the VIKOR comprises the steps of adopting the Pictgomery fuzzy set for evaluating alternative suppliers and evaluating index importance; respectively calculating subjective weights and objective weights of the evaluation indexes according to the evaluation data, and obtaining combined weights; and according to the alternative scheme evaluation and each evaluationindex weight, sorting the alternative suppliers by using a VIKOR method based on a Bigomery fuzzy set and determining an optimal supplier. 本发明提出了一种基于毕达哥拉斯模糊集和VIKOR的供应商选择方法，属于供应商评价及选择技术领域。该基于毕达哥拉斯模糊集和VIKOR的供应商选择方法包括：使用毕达哥拉斯模糊集评价备选供应商以及评价指标重要性；根据评价数据，分别计算评价指标的主观权重和客观权重，并得到组合权重；根据备选方案评价和各评价指标权重，使用基于毕达哥拉斯模糊集的VIKOR方法对备选供应商排序并确定最佳供应商。
