Research on Affordability Modeling of Aircraft Based on Effectiveness Indexes

With the cost estimation of military aircraft as the research object,this paper aims to study the contradiction between the choice of explanatory variables in index modeling and the maintaining of model validity.It analyzes and establishes a cost estimation modeling concept based on an Effectiveness Index and studies the way to construct Effectiveness Indexes for the sake of cost estimation modeling.Based on a case study,the paper establishes and analyzes the Effectiveness Index-based cost estimation models...
