Abstract: Aiming at the general design and proper plan of earth observation system, the hierarchy efficiency evaluation index system was derived, and the analytic hierarchy process (AHP) approach was used to get the weight of index. The acquisition and nondimensionlization method for the qualitative and quantitative index was given. The efficiency evaluation model was derived based on fuzzy synthetical computation, and the membership function approach and the experts scoring method were used separately to compute fuzzy evaluation vector of the qualitative and quantitative index. Finally, a multi-level system efficiency evaluation flow path was put forward based on AHP-FCE(Fuzzy synthetic evaluation), and the effectiveness of the given approach was verified by a mathematical example.
