| Port and shipping system(PSS),which is an important part of the traffic and transport industry,has a tremendous space and potential to save energy,lower energy consumption and reduce pollutants discharge.However,the port and shipping system has not yet been setted up a perfect evaluation system for energy-saving emission reduction(ESER) in P.R.China.How to evaluate ESER performance in the way comprehensive,objective,scientific,is an issue which urgently needs to be addressed. The purpose of this paper is to establish a comprehensive evaluation index and method in accordance with the objective reality of the port and shipping system and to provide a scientific evaluation basis,and to put forward proposals and measures related for energy-saving emission reduction,which will has a practical significance to promote energy-saving emission reduction work continuously and rapidly develop for port and shipping system.First,the development status of energy-saving emission reduction for pot and shipping system in domestic and international was analyzed,and the systematic evaluation theory was studied.In accordance with the guidance and requirements of China's energy-saving emission reduction ideas,an evaluation model of energy-saving emission reduction was based on Analytic Hierarchy Process(AHP)-Fuzzy Comprehensive Evaluation(FCE) method for port and shipping system,which following the principle of qualitative and quantitative analysis.Then,the method of AHP-FCE is used to establish the index system and evaluation method.After that,the port and shipping system of some province was setted as an example for empirical studying.Finally,the gray relational analys is used to improve the method to the fuzzy evaluation and relevantly recommendations and measures were proposed to improve the work of energy-saving emission reduction for port and shipping system.Theory and case to prove:(1)In some extent,it is a scientific method to use the AHP-fuzzy comprehensive evaluation method evaluation on the performance of the energy-saving emission reduction for PSS.This method can simplify the complexity of the variety of influencing factors in the coexistence,and to a certain extent,reduce the impact of the evaluation results because of subjective preferences,also be an effective method to overcome the one-sided of single indicator;(2) The specific content and related emphases were cleared by using the fuzzy analytic hierarchy process to deal with the weight of the evaluation index;(3)The gray relational analys of the gray system theory was used to improve the fuzzy evaluation,which in order to better resolves the problem of the information lost and sequence of the evaluation results;(4)Through the research and analysis of the evaluation example,evaluation results in line with the actual situation,which shows that this evaluation method has the strong operational,the higher the accuracy,and has some role of guide and reference for energy-saving emission reduction of national PSS. |
