The postapplication effect of meteorological instrument equipment achievements is studied. Some details of the corresponding evaluation index system, such as classifying the evaluation objects, analyzing essential characteristics, and exploring indices, are introduced. The weights of various indexes are calculated based on the analytic hierarchy process (AHP) method. The comprehensive scoring method is proposed to carry out simulation evaluation. The results show that the evaluation index system and the proposed method have the practical operability and the findings provide a reference for meteorological science and technology evaluation management.
