Abstract

As the urban sprawl, the influence of city logistics on economy, society and environment is more and more remarkable, so city logistics receives increasingly attention recently. Since the city logistics system is a complex system affected by many factors, and these factors affect each other, it is difficult to improve all the influence factors at the same time to enhance the performance of city logistics. Therefore, there is need to find out the key influence factors of city logistics in order to improve them gradually. Considering the vagueness of human judgments, this paper pioneers in exploring the decision-making trial and evaluation laboratory (DEMATEL) method combining with fuzzy logic to identify the key influence factors of city logistics. According to analysis results, six key influence factors are identified,which are helpful to propose a comprehensive measure. As the implementation of this comprehensive measure, all other factors can be improved step by step. Finally the development level of city logistics might be improved.
