机场净空障碍物危险度的白化权聚类评价

摘要

为将灰色理论引入机场净空障碍物危险度评价，建立四个评价指标，将障碍物危险度等级划分为五个标准，使用灰色白化权聚类法建立机场净空区障碍物危险度评价模型，包括每个指标的白化权函数和权重确定，在此基础上，机场所有的障碍物及机场整体的危险度等级可确定。以某机场为例对其净空障碍物进行整体评价证明，基于灰色白化权聚类法的机场净空区障碍物危险度评价模型可用于解决民用机场净空区内障碍物危险度定量评价问题。%The paper evaluate the danger degree of obstructions in airport clearance area by using grey system theory,which is the first time in the field .Firstly,Evaluation model of danger degree of obstruc-tions in the airport clearance area based on grey whitening weight function clustering method was estab-lished on four aspects .Then danger degrees of obstructions in airport clearance area were classified ,which included 5 levels.Then with the application of grey whitening weight function clustering method ,an evalu-ation model of danger degree of obstructions in the airport clearance area was established ,including con-structing the whitening weight functions and measuring the whitening weights of the four indicators .After that,a danger degree of each obstruction and of the whole obstruction system in the airport clearance area was deduced by applying the model .At last,the model was verified by an example on an airport ,which in-dicated that the model was suitable for evaluating the safety of airport clearance area ,and for assisting ob-structions′danger degree decision quantitatively .
