基于灰色聚类的飞机技术派遣决策参数组合权重确定

Determination of Combination Weights in Aircraft Technical Dispatch Based on Grey Clustering

为了保障民航飞行的安全性与航班运行的正常性,要使用科学有效的方法对执行航班的飞机进行技术派遣。对各类影响飞机技术状况的决策参数进行分级,依据灰色聚类的基本原理,定义相应的白化权函数,在此基础上,利用信息熵确定参数的客观权重,并使用指数乘法合成归一化组合方法求出组合权重,最后将该方法应用于某航空公司飞机技术派遣决策参数权重计算。结果表明该方法计算出来的组合权重与航空公司目前采用的工程经验纬度权重具有较高的吻合度。

To ensure the civil aviation flight safety and dispatch reliability, it is necessary to use scientific and effective methods to dispatch the aircrafts technically. All kinds of event parameters affecting aircraft technical status were graded. The parameters were clustered by the corresponding definite weighted func- tions based on basic principle of grey clustering. Based on this, the objective weight of parameters was de- termined by adopting the information entropy. The combination weights were obtained by applying the combination of exponential multiplicative synthesis. Finally, the method was applied to the parameter weight calculation of technical dispatch of a certain aircraft. The results showed that the combination weights calculated by this method had a high degree of agreement with the engineering experience.
