| Abstract: | Based on the structure analysis of the typical aerospace static test,the cost estimation relation,Delphi method and statistic analysis are used to study the factors of the hardware and software in the different static test periods.The main factors that affect the test pricing are selected,and the price-factors relation method is used to design the pricing model of static test.The experts pricing formula and statistical pricing model are established,and they are obtained under the history test price data.The... |
