A Fuzzy Comprehensive Assessment Model for Reflection of Dominant Factors

The fuzzy comprehensive assessment models commonly used are usually static weight model, which can not reflect the prominent influence of single factor. To solve this problem, this article shows a new alterable weight model which can be widely used. The new model can reflect the prominent influence of single factor, and can also regard the commonly used fuzzy comprehensive assessment model as its special case. Based on this modified model, the case analysis of water quality got a more reasonable result, which shows the advantage of the modified model. This model is especially applicable in the continuous, timely, dynamic evaluation, and it will be widely used in the timely evaluation in the fields of military, economic, environment, etc.
