基于综合赋权和未确知测度的火灾风险评价

为准确评估商场火灾风险,建立了基于综合赋权法的未确知测度评价模型,该模型利用未确知测度建立单指标测度评价矩阵,基于IIAHP、熵、离差平方和最大化计算评价指标的综合权重,从而得到评价对象的综合测度评价向量,最终判定风险等级和排序.利用建立的模型对商场火灾风险进行评价,选取了16个影响商场火灾风险的评价指标,建立了评价指...

Fire risk evaluation based on comprehensive weighting and uncertainty measurement

To get an accurate evaluation of fire risk in malls, uncertainty measurement evaluation model was built based on comprehensive weighting method. In this model, single index measure evaluation matrix was built by uncertainty measurement. Comprehensive weight of evaluation indexes was calculated based on IIAHP, entropy and sum of deviation square maximizing. Comprehensive measure evaluation vectors of evaluation objects were obtained by single index measure evaluation matrix and comprehensive weight of evaluation indexes. Risk rating and sequencing were judged by comprehensive measure evaluation vectors. Fire risk of malls was evaluated by the established model. 16 evaluation indexes of affecting malls fire risk were selected and uncertainty measure functions of evaluation indexes were built. Fire risk rating and sequencing of 4 malls were obtained by field datum of evaluation indexes. Analysis showed that risk rating and sequencing are consistent with the safety situation of malls. The evaluation results have application value.
