城市大型商场火灾风险评价的投影寻踪模型与应用
Fire Risk Comprehensive Evaluation of the Large Urban Building based on Projection Pursuit Clustering Model and its Application
摘要
Abstract
Based upon the fire risk comprehensive evaluation (FRCE) index system of the urban shopping malls (USM) and its five-class evaluation criteria,the projection pursuit clustering (PPC) model for FRCE of the USM were established by applying group search optimization (GSO) in this paper.The reliable and effective results of unknown fifteen samples were obtained by applying the PPC model.The results applying PPC model are good agreement with the results using the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) and gray relation analysis (GRA) based on information-entropy weights.The shortcomings of the published literatures on FRCE using neural networks are discussed and analyzed,and these established BPNN models are unreliable,non-generalized and useless.The case study shows that the PPC model is robust and suitable for FRCE of the USM.The PPC models possess the characteristics of clear concept and convenient application.关键词
