Abstract

The maritime Aids to Navigation (AtoN) plays a vital role in ensuring safety and efficiency of the water transport. The efficacy evaluation of AtoN is closely associated with the arrangement of navigation aids in both river and port waters. Qualitative description methods are known as convenient but sometimes subjective. A few attempts in the literature review have been conducted for quantitative evaluation. In the present study, a numerical model has been presented by adopting Analytic Hierarchy Process (AHP) and Fuzzy theory. The index evaluation system is established considering the characteristics of the navigation channels in the research domain. The weight of each index is then determined. The judgment matrix is finally combined with the data analysis of the expert questionnaire to achieve quantitative evaluation of the AtoN efficacy. The results indicate that the efficacy of AtoN is overall favorable (with a mean value of 8.0 out of 10) under current arrangement. The proposed quantitative evaluation method could provide a guidance for maritime safety administration.

基于模糊层次分析法的海事AtoN效能评价

海上助航设备对保证海上运输的安全和效率起着至关重要的作用。导航仪的效果评价与河港水域助航设备的布置密切相关。定性描述方法是众所周知的方便，但有时是主观的。在文献综述中进行了一些量化评价的尝试。本文采用层次分析法(AHP)和模糊理论建立了一个数值模型。结合研究区域内航道的特点，建立了指标评价体系。然后确定每个指标的权重。最后将判断矩阵与专家问卷的数据分析相结合，实现对AtoN效能的定量评价。结果表明，在目前的安排下，AtoN的效果总体上是有利的(平均值为8.0分)。所提出的定量评价方法可为海上安全管理提供指导。
