针对港口绿色化评价体系构建的问题,结合港口交通与能源融合发展理念,研究了一套规划方案综合评价方法.方法综合考虑了清洁能源可获得性自然禀赋、能源负荷特征及自洽能源系统规划容量等多种因素,构建了包含经济性、环境性、能效性、自洽性和可靠性5个维度的自洽能源系统规划方案评价指标体系,并基于这些指标建立了相应的量化评价模型.为解决数据匮乏问题,采用层次分析法(analytic hierarchy pro-cess,AHP)和熵权法(entropy weight method,EWM)分别计算各指标权重,并采用博弈集结模型确定评价指标的组合权重.最后,采用TOPSIS综合评价方法对不同规划方案进行综合评价,通过以某港口智能化集装箱港区A的示范项目作为案例进行验证.采用传统熵权法(EWM)、秩和比法(rank sum ratio,RSR)和基于熵权的多准则妥协解排序法(EWM-VIKOR)对上述算例进行方案排序,并与本文所提出的综合评价方法(AHP-EWM-TOPSIS)进行对比验证;通过改变方案原始排名第1的方案2中某个指标的数值作为测试数据集进行评估,确定各评价指标在一定范围内变动时是否引起方案排名结果变动,同时找出影响方案排名结果的最敏感的指标比较不同评价方法的鲁棒性.结果表明:不同方法得到的方案排序结果一致,验证了该模型的有效性;AHP-EWM-TOPSIS方法在评价结果的稳定性优于EWM-VIKOR.
A Comprehensive Evaluation Method for the Planning of Self-Sufficient Energy System for Ports Based on Improved Composite Weighting
This study develops a comprehensive evaluation method for green port planning schemes,integrating the concepts of sustainable port transportation and energy management,to address the issue of constructing a green port evaluation system.The method considers critical factors including the availability of clean energy resources,energy load characteristics,and the capacity for planning a self-sufficient energy system.An evaluation index system for self-sufficient energy system planning is established across five dimensions:economic feasibility,environmental im-pact,energy efficiency,self-sufficiency,and reliability.Based on these indicators,a quantitative evaluation model is developed.To address data limitations,the analytic hierarchy process(AHP)and entropy weight method(EWM)are used to calculate weights individually,while an aggregated game theory-based model is used to determine the combined weights of the evaluation indices.The Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)is then employed for the comprehensive assessment of different planning schemes.A demonstration proj-ect from an intelligent container port(Port Area A)serves as a case study to verify and validate the model.The pro-posed AHP-EWM-TOPSIS method is compared with traditional methods,including the entropy weight method(EWM),rank sum ratio method(RSR),and the Entropy-weighted VIKOR method(EWM-VIKOR),to assess the stability and sensitivity of scheme rankings.By altering a specific index in the top-ranking scheme(Scheme 2)as test data,the model's robustness is evaluated in terms of ranking consistency and sensitivity to index variations.Re-sults indicate that scheme rankings are consistent across methods,verifying the model's effectiveness,with AHP-EWM-TOPSIS demonstrating superior stability over EWM-VIKOR.
