为客观反映城市消防安全水平,本文提出了一种灰色关联投影算法的城市消防安全评估方法。通过分析系统运行流程,建立指标体系,确定评估模型等步骤,实现了基于灰色关联投影算法的城市消防安全评估。并以江苏省部分城市消防为实例进行了实际计算,从结果看,基于该算法城市消防安全评估模型科学,体系合理,符合客观实际。 In order to objectively reflect the level of urban fire safety, this paper presents a gray correlation projection algorithm for urban fire safety assessment. Through the analysis of system operation flow, establishment of index system, determination of evaluation model and other steps, the city fire safety assessment based on gray relational projection algorithm is realized. And some cities in Jiangsu Province fire as an example for the actual calculation, from the results, the city fire safety assessment model based on the algorithm of scientific, rational system, in line with objective reality.
