Fuzzy comprehensive evaluation on supply chains' total performance based on improved algorithm

The performance evaluation of supply chains is the key of effective supply chain management, which is not only helpful to describe and analyze the historical performance and status, but also can be used to set performance targets and determine the future focus. The paper, according to the shortcomings of existing fuzzy comprehensive evaluation models, eliminated the redundant data in index membership for object classification by defining distinguishable weight and extract valid values to compute object membership and apply the new algorithm in the fuzzy evaluation on supply chains' total performance. Evaluation results of examples showed the validity of the improved model, and the model achieved the dynamic evaluation of supply chains' total performance, which can provide the basis for researchers to study how to improve the operation performance of supply chains and for enterprises to implement performance evaluation of their supply chains.
