基于风险矩阵法的封闭空间空气安全风险评估模型

摘要

为提高城市人防工程等地下大型封闭空间空气质量评估的客观性,提出基于风险矩阵法的封闭空间空气安全风险评估模型.构建二维矩阵,定量计算出受评实体的风险要素,再利用Borda序值理论和层次分析法(analytical hierarchy process,AHP)得出各风险要素的权重,最后利用风险矩阵得出实体风险等级值,以某人防工程为评估对象进行实例计算.计算结果证明:该方法将定性的过程定量化,很大程度上减少了人为失误带来的损失.%A assessment model which based on risk matrix is proposed in this paper, for improving objectivity of the air security assessment on big enclosure space such as defense construction. Risk factors of the enclosure space are counted quantitative by two dimension matrix. The weight of the risk factor is got by Borda and AHP (analytical hierarchy process). The risky numerical value is reckoned by the risk matrix and a storehouse is taken for an example. It proves that the assessment model can quantify qualitative process and reduce factitious loss in a large part.
