An effective method for performance evaluation of ACLS based on improved grey analytic hierarchy

The performance evaluation of automatic carrier landing system(ACLS)is an important part in the field of carrier aircraft landing control.Combining grey analytic hierarchy theory and data normalization theory,an improved grey analytic hierarchy method is introduced to evaluate the performance of ACLS.A complete performance evaluation indicators system of ACLS is established,and the definition and calculation formula of each indicator are provided.The grey analytic hierarchy model is modified to improve the real-time performance of the algorithm,where traditional expert scoring sampling matrix is substituted by an indicator normalized sample matrix.Taking a certain ACLS as an example,the experimental simulation is carried out,and the simulation results verify the reliability and the accuracy of the improved grey analytic hierarchy method.

基于层次灰色模型的铁路技术创新绩效综合评价

运用技术创新基本理论,结合铁路技术创新实际,从效益(经济、社会)增长、市场状态(市场份额、市场营销)改善和创新主体素质(技术装备水平、管理水平)提高3个方面建立了评价铁路技术创新绩效的多级指标体系。将层次分析法(AHP)和灰色系统理论结合起来建立了层次灰色评价模型(HGM),运用该模型对铁路技术创新绩效分别从整体和分项进行了综合评价,得出:铁路技术创新绩效绩优度为“一般”,其主要原因在于铁路运输市场状态改善中市场份额扩大程度较低。实证分析结果表明:改进层次灰色评价法(层次灰色评价模型)为一种评价铁路技术创新绩效的有效方法。
