Abstract

According to the defects of fuzziness of index of fire risk evaluation and the complexity of structure consistent pair-wise comparison matrix, the fuzzy consistent matrix was introduce, by doing this, the influence of subjective factors could be reduced effectively. The paper established a Fuzzy Analytic Hierarchy Process model which aimed at assessing the tunnel fire risk assessment of subway by combining the fuzzy consistent matrix and AHP. Then a subway tunnel was selected for example, considering the hierarchical model of the complex index system carefully, Firstly, building it's fuzzy consistent matrix which tolerate ambiguity and vagueness, calculating the weight of various factors with the fuzzy theory; Secondly, quantifying the fire risk of subway tunnel with the aid of the fire risk index method and the grade of the fire disaster danger grades could be drawn. Thirdly, the weak link of the system could be found by assessing the weight of various factors which can guide the fire safety work during designing, constructing, operating and so on. The inconformity of the pair-wise comparison matrix could be avoided by using this model. This model would shows greater superiority over the engineering.
