On the basis of China port’s current requirements and development status in energy saving, we establish the port energy saving evaluation system, using AHP to determine the weight of each index, and based on AHP-fuzzy comprehensive evaluation method to get scores of port energy conservation in order to judge the advantage and disadvantage of port energy saving. Moreover, we evaluate the energy saving work of Qingdao port comprehensively, the results of which may serve as a reference for energy conservation in port and other industry.
