Abstract: Weight determination is a puzzle subject in the comprehensive assessment of the objective characteristics of things,and has not been solved so far.Taking as an example the comprehensive assessment of gas-bearing bed of carbonate rock,and using the method of grey relational anAlysis,this paper has successfully solved the problem of weight determination in fuzzy comprehensive assessment.With this achievment the comprehensive assessment can be made to be more in consistent with the objective reality and a good way also be provided for the wide use of the comprehensive assessment.

Key words: Weight, Fuzzy comprehensive assessment, Grey relation lanalysis, Assessrnent index
