The initiation risk and performance assessment of meteorological research projects are studied in this paper,with 51 meteorological projects supported by the special scientific research fund of public welfare profession,initiated by the ministry of science and technology,as assessment objects.The risk evaluation index system is built through comprehensive analysis and judgment from aspects of applicant background,technological difficulty,expected achievement and management control.A risk evaluation model is proposed based on fuzzy theory,to assess the initiation risk of the meteorological projects,and 51 projects are therefore evaluated to provide references for decision making.The performance and promotion value appraisal method is put forward based on AHP,and the promotion values of the 51 meteorological projects are assessed using this multi-index evaluation method.
