For the problem of supply chain risk factors identification, a method is proposed to solve the problem of risk factor identification in supply chain. Firstly, a system of supply chain risk factors is constructed. Then, taking account of the linguistic interval judgment information describing the degree of direct influence between risk factors given by experts, a method to identify supply chain risk factors considering mutual influence between risk factors is presented. Based on the idea of DEMATEL, 2-tuple fuzzy linguistic representation model developed in recent years is used in this method to process and aggregate the linguistic interval judgment information, thereby ranking and classifying supply chain risk factors. Finally, an example shows the feasibility and effectiveness of the proposed method.
