Research On Sustainable Supplier Selection Based On Fuzzy GRA

With the development of science and technology in human society,social and environmental problems have become increasingly prominent,and all sectors of society require enterprises to assume more social responsibilities.The selection of sustainable suppliers in supply chain management plays an important role in undertaking social responsibilities and gaining market competitive advantages.In this paper,the fuzzy GRA decision model is constructed based on the linguistic decision theory,and applied to the sustainable supplier selection of equipment manufacturing enterprises.The sensitivity analysis and comparative analysis verify the scientific and reasonable method proposed in this paper,which can provide reference for enterprises to make decisions in similar fields in the information age.The research contents of this paper are as follows:(1)Construct an indicator system for sustainable supplier selection.This paper analysis the sustainable supplier selection research actuality based on domestic and international of literature.Furthermore,the paper explains the related theory,and builds the index system of economic,environmental and social three aspects that uses the method of literature review and discussions with experts based on the triple bottom line theory.The index system includes quantitative indicators such as price and quality,as well as qualitative indicators such as environmental management system,safety and health,and impact on local communities.(2)The theory of interval-valued probabilistic linguistic term set is studied and the weighted power-average operator of interval-valued probabilistic linguistic is proposed.This article reviewed interval-valued probabilistic linguistic term set related knowledge,including algorithms,score,distance formula and so on,its power average operator is extended to,put forward the corresponding power average operator and weighted power average operator,and demonstrate the idempotency,replacement and boundedness,apply it on multiple intervalvalued probabilistic linguistic term set.(3)A sustainable supplier selection method based on fuzzy GRA is proposed.Firstly,the expert weight is determined by Shapely value based on cooperation and game among experts.Secondly,the advantages of LBWA method are simpler and have fewer comparisons of indicators,so the weights of sustainable supplier of indicators are determined by LBWA method.Furthermore,the paper builds fuzzy GRA method based on real number and intervalvalued probabilistic linguistic term set.And the method is applied to an instance of sustainable supplier selection of equipment manufacturing enterprise and does a sensitivity analysis and comparative analysis further.Through the comparison of methods,it is found that the method of this paper is scientific and effective,and more in line with the actual situation of the decision-making environment...
