基于熵权-TOPSIS-灰色关联的航道宽度设计结果评价*

通过对国内外3种不同的航道宽度设计规范进行分析对比，从通航安全和效率的角度建立综合评价指标，旨在 对不同的航道宽度设计结果进行排序，为航道宽度的合理设计提供借鉴。建立熵权-TOPSIS-灰色关联度综合评价模型，采 用熵权法获取各指标的客观性权重，分别获取备选方案与正理想解和负理想解的正、负灰色关联度，综合得出各方案的灰 色关联相对贴近度，从而进行方案排序与优选。并假定评价环境，对3种不同的设计规范进行了实例分析与评价，从安全、 效益和综合水平上给出了各规范在假定环境下的设计效果排序情况。评价结果基本符合实际情况，可以对航道宽度设计规 范的进一步研究与发展提供一定的基础。

Entropy weight-TOPSIS-grey correlation method on assessment of channel width design result

For ranking and comparing different design results of the channel width given by different codes to promote the reasonable design of channel width, comprehensive evaluation indices are determined from the point of navigation safety and efficiency after analyzing and comparing three different kinds of channel width design codes. The entropy weight-TOPSIS-grey correlation comprehensive assessment model is built, in which, the objective weight of each index is obtained from the entropy method. The positive & negative grey correlation grade between alternative schemes and positive & negative ideal solution are calculated respectively, and the grey correlation relative closeness between each alternative and ideal solution is obtained. So the scheme ranking and optimization can be achieved based on the relative closeness. Given practical assessment situation, three different kinds of design codes are taken into practical example analysis and assessment. Then, from the view of navigation safety, navigation efficiency and comprehensive benefit, the reasonability of the channel width given by different codes for the given situation is clarified. The assessment result tallies with the actual situation and can provide the basis for further study and development for the channel width design code.
