The evaluation system structure of servo configuration of the machinery was studied considering its characteristic in production, running and service. The analysis and calculation of the evaluation index of the servo configuration of the machinery was realized using fuzzy set, analytic hierarchy process, and range analysis method. A servo configuration design system based on iSIGHT was developed, and the alternatives were evaluated by using technique for order preference by similarity to ideal solution (TOPSIS). An example of servo configuration was used verify the proposed approach. The result showed that the proposed approach with FAHP and TOPSIS can perform the configuration evaluation more effectively and objectively for the machinery.
