Study on the Estimation Model of Ammunition and Rocket System Development Cost Based on the Residual Error Correction

The estimation of ammunition and rocket system development cost often adopts the method of multiple variable linear regression equation. The method requires a great number of sampld data and shows a low estimation accuracy. During the new-type ammunition and rocket system development, the small or limited number of the samples maks it very difficult to estimate the development cost. This paper suggests that the n-degree cumulative residual error model should be used to correct the parameter model so as to solve the problem mentioned above. The examples indicate that a higher accuracy can be obtained with fewer samples by this method.
