Research on the Cost Estimating of China´s Aviation Aircraft Development Project Based on the Parametric Method

The modern aircraft development work has so more significant characteristics, such as the more complex product structure, the longer development cycle, the higher risks and poor reproducibility, that the cost estimating of development project is difficult. Based on the Parametric Cost Estimating method, analyzing the influencing factors of aircraft development project costs, using the correlation analysis to determine the key influencing factors of project costs and establish the cost impact factor model. And on this basis, using multiple nonlinear regression analysis method to establish the aircraft development project cost estimation model. Finally, the recommendations of using the Parametric Cost Estimating method to estimate the cost of China´s aviation aircraft development project are given from the three aspects of enterprise, development institution and government.
