摘要
为提高高危行业安全管理水平,研究风险要素的评价模型。借鉴作业条件危险性评价LEC法理论意义,针对其主观性和间接性太强的缺憾进行了实质性地改进。同时,通过给出风险源强度评估模型及各风险要素强度评估模型,设计同类型同等级事件风险要素的风险贡献度模型。在此基础上,结合改进后的LEC法,建立同类型同等级事件风险要素的风险值模型,风险警戒标准模型以及风险警戒状态模型。验证结果表明:所建模型对风险要素的评价与实际情况较为吻合。
In order to improve the level of high-danger industries risk management, research into fish factors＇ evaluation models was made. The classical LEC method was improved essentially, a risk contribution model of same type and level incidents＇ risk factors was built. Combining with the improved LEC method, a risk value model, a risk alert standard model and a risk alert status model were built. Verification results show that the models run well.
