基于多目标属性决策和信息熵值法的港口集装箱装卸设备选型评价

摘要

装卸设备选型对专业集装箱码头的发展具有重大意义,本文从这一现实问题入手,基于集装箱装卸设备选型的多属性特征以及港口物流工业的一体化趋势,提出了基于信息熵值法的多目标属性决策模型(Multi-attribute decision-making Model Based on Information Entropy Method,MADM-IEM).以装卸设备为研究对象,构建全面的装卸设备选型评价指标体系;针对指标属性不相容性和不确定性、相关指标难以量化呈现的特点,运用多属性决策和信息熵值法的数据效用值相结合的方法,客观、合理地计算属性指标的权重系数,并进行归一化处理;在此基础上结合ELECTRE法和TOPSIS法,对装卸设备进行综合排序,由此确定设备选型结果.注意到,两种方法求解结果具有一致性,验证了该模型的可行性和有效性.最后对港口装卸设备选型评价进行灵敏度分析,深入讨论评价指标的权重变动对结果的影响.研究结果充分表明提出的MADM-IEM模型能为中小型内河港口码头的基础建设规划提供科学合理的决策依据.%Handling equipment selection is of great significance for the development of specialized container terminals,and hence it is addressed in this article.Recognizing the multi-attribute nature of container handling equipment evaluation and the integrative trend of port logistics industry,we introduce a multi-attribute decisionmaking model based on information entropy method(MADM-IEM).Taking handling equipment as the research object,we propose a comprehensive handling equipment evaluation index system.In the handling equipment evaluation model,the indices are featured with incompatibility,uncertainty and difficulty to quantify.Therefore,the multi-attribute decision-making method and data utility value of information entropy method are integrated to objectively both normalize and calculate the weight coefficient of attribute indices.For the ranking of different handling equipment options,the ELECTRE method and TOPSIS method are utilized separately,which results in consistent outcomes and verifies the feasibility and validity of the proposed method.Finally,the sensitivity analysis and causality analysis between weight combinations and the port terminal handling equipment evaluation results are thoroughly investigated.The research results indicate that the proposed MADM-IEM model could be used to facilitate the decision making regarding the container port infrastructure planning.
