| Abstract: | A cost model based on gray theory is made for the airframe cost estimating of uninhabited combat air vehicles(UCAV).The sample data of UCAV is simulated by the transformation of modified manned attack fighters and the cost sample data is also created using DAPCA Ⅳ cost model for the same airplanes. Gray model has a good ability of forming a rule through accumulated generation operation and inverse accumulated generating operation. Therefore it makes gray model be used widely in model making, especially in... |
