基于效能指数的军用飞机经济性建模

以军用飞机整机的费用估算为研究对象,探讨解决参数模型构建过程中合理选取说明性变量与保持模型有效性之间的矛盾,分析并确立了基于效能指数的费用建模思路,针对费用估算建模的需要研究了效能指数的构建方法.通过一个实例分析,建立和分析了基于效能指数的费用模型.作为比较,同时采用DAPCA模型形式建立了模型.结果表明:基于效能指数的费用参数模型既比较全面地考虑了对费用有明显驱动的参数指标,又减少了回归分析的变量数,从而使模型具有较强的有效性.

Research on Affordability Modeling of Aircrafts Based on Effectiveness Indexes

Aimed at the whole military aircraft,the paper tries to solve the contradictory between keeping model effective and choosing the right expository variables.The basic modeling idea based on Effectiveness Indexes is analyzed and the form of models is established.According to the demand of cost modeling,the Effectiveness Indexes' constructing method is studied deeply.Finally,the cost modeling process based on Effectiveness Indexes is introduced through an example.In order to compare the effect of methods,some ...
