Comprehensive Evaluation Method

For the accuracy of the inrush risk assessment of the problem, put forward in the mine inrush risk assessment using the entropy weight fuzzy comprehensive evaluation method to determine the index weight, through the membership function in fuzzy comprehensive evaluation to quantify the qualitative description of these factors, evaluated the henan jiaozuo mine inrush risk. The results show that the mine water inrush risk grade is "great", the actual mine water inrush accidents have occurred, prediction results conform to the actual situation, and safety evaluation value based on the principle of maximum membership degree is more than analytic hierarchy - fuzzy comprehensive evaluation to get , 0.0696. Thus, the method in the mine inrush prediction can objectively and accurately reflect the actual situation of mine inrush.

According to the characteristics of subway construction in Tianjin, a risk assessment indicator system has been established in subway construction. On the basis of traditional AHP (Analytic Hierarchy Process), the introduction of the concept of triangular fuzzy numbers evaluates the weight of risk factors in a more accurate and objective way. Adopting a fuzzy comprehensive evaluation mathematical model, by constructing membership matrix, the metro construction is not difficult to quantify the risk factors with the scientific evaluation methods. It can be proved that fuzzy comprehensive evaluation method used in subway construction process is a scientific, effective evaluation method.
