Metro station fire safety evaluation database
This paper introduces the data of fire safety evaluation of subway station. Experts were invited to assign the security evaluation index status of each site to get the original data matrix. The first step is to determine the weight of the evaluation index: By combining cloud model with AHP, the subjective weight of indicators is calculated by the importance evaluation matrix. The objective weight of the index is measured by the amount of information carried by the factor. Then, the optimal weight value is obtained by using the combined weighting optimization model of least square method. In the second step, the concept of cloud model is introduced, and the membership matrix is determined according to the index value through the forward cloud generator. Then, the evaluation cloud model matrix of each index is determined and multiplied by the index weight matrix to determine the comprehensive evaluation cloud model.
