Research for application of group decision method on appraisement system of science research schema

Appraisement of science research schema is a kind of group decision problem including multiple objects and multiple factors. In order to increase the level of science and impartiality of the appraisement, the paper studies the construction of a cascade index system and elimination method under asymmetry status, employs a fuzzy multiple hierarchy integrative judgement method to perform sorting and appraising of schemas, and argues for the method of combining Delphi and AHP to confirm the weight of the index.
