To solve acquired the membership degree in fuzzy evaluation. we use correlation function extension theory to calculate of association between evaluation indicators and scales, then is done standers conversion normalized processing,, getting value matrix comprehensive Comprising traditional statistical methods expert method, which gat through method more simple reasonable. Comprehensive got from Calculating linear weighted index weight coming analytic hierarchy process. Finally, using two type home made NC machine tools as example do practical application study proposed results show that this can give reasonable
