New Method for Suppliers Selection under Uncertain Environment of the Supply Chain

Existing suppliers selection methods are mostly for certain environment. However, this environment is usually uncertain in practice. Therefore, the study of the suppliers selection under the uncertain environment has an important theoretical and practical application value. Based on Gray Theory, AHP and Fuzzy Opinion Centralized Sequence, this paper construct a new fuzzy ranking method to select suppliers. First, a correlation matrix model is established under the Gray Theory, the weight of every evaluation index is determined by AHP. Then the best supplier is judged and chose under the Fuzzy opinion centralized sequence.
