The proposed evaluating method based Cloud Model and Gray Relational Degree aims to solve the fuzziness and randomness problems of evaluation methods and the outcome efficiently. Cloud model is implemented to convert qualitative concept into quantitative value based index system. Gray Relation Degree theory is implemented to access to evaluation index weights.
