“…If we want to get comprehensive evaluation, two parts can be divided, one part is the determination of evaluation index and the weight distribution; the other part is the establishment of the evaluation model [4]. The doctors of Jia Yazhou and Wang Guiping evaluate the CNC machine tool's green degree through fuzzy extension analytic hierarchy process [5], in evaluation model, the fuzzy single factor results are made by experts, lack of objectivity, and relatively complicated especially there are too many indexes [6][7][8].…”

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