Abstract: A new evaluation methodology about manufacturing informatization engineering requirement analysis (MIERA) is proposed，and an index system is designed for it.Moreover, Analytic Hierarchy Process (AHP) is used to calculate the index values and weights. By choosing the suited fuzzy subject function and establishing fuzzy relationship matrix, fuzzy judgment is applied to get an integrated value of MIERA so that the level of MIERA is confirmed．At last，a method are put forward to solve the uncertainty and non-standardization of MIERA, which make for enterprises to find the bottleneck when implementing MIE.
