在分析参数法成本估算的基础上,针对飞机研制项目分析成本影响因素,运用相关性分析确定影响成本的关键影响因素,构建飞机研制项目成本影响因素模型,并在此基础上运用多元非线性回归分析建立飞机研制项目的参数法成本估算模型,最后从航空飞机制造企业、研发机构和政府三个角度对我国航空飞机研制项目实施参数法成本估算提出建议。
On the basis of analyzing the cost estimation of the parameter method, this paper analyzes the factors influencing the cost of the aircraft development project, uses the correlation analysis to determine the key influencing factors of the cost, constructs the model of the influencing factors of the cost of the aircraft development project, and uses the multiple nonlinear regression Analyze and establish the parametric method cost estimation model of the aircraft development project. Finally, put forward some suggestions on how to estimate the cost of the parameter method in China’s aviation aircraft development projects from the perspective of the aircraft manufacturing enterprises, R & D institutions and the government.
