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.本文介绍了地铁站消防安全评估数据集。邀请专家对各站点的安全评估指标状态进行赋值，以此获取原始数据矩阵。第一步为确定评估指标权重：将云模型与层次分析法（Analytic Hierarchy Process, AHP）相结合，通过重要性评估矩阵计算得到指标的主观权重；利用指标因子所携带的信息量衡量指标的客观权重；随后采用最小二乘法组合赋权优化模型，求解得到最优权重值。第二步引入云模型概念，通过正向云发生器依据指标数值确定隶属度矩阵；随后确定各指标的评估云模型矩阵，并将其与指标权重矩阵相乘，最终得到综合评估云模型。
