Study of Green Supply Chain and its Performance Based on Fuzzy AHP and Measurement System

The paper analyses that it is unsuitable to apply the evaluation system of general supply chain to the evaluation of green supply chain. The influence factors of the performance of green supply chain are put forward in accordance with the characteristics of green supply chain. The analytical hierarchy process (AHP) method has been widely used for solving weight problems. However, the conventional AHP method is incapable of handling the uncertainty and vagueness involving the mapping of one´s preference to an exact number or ratio. This paper presents a fuzzy AHP model to overcome this problem. The proposed approach employs triangular and trapezoidal fuzzy numbers and the a-cut concept to deal with the imprecision inherent to the process of subjective. The model can accurately and objectively evaluate the performance of green supply chain. The effectiveness and correction are tested by an application case.
