摘要
将复杂社会网络(SNA)与N-K模型的融合风险因素分析体系引入氢能储运系统安全风险评价中.收集整理国内外近 20 年来氢能储运事故案例;运用N-K模型计算风险耦合值并确定事故耦合形式,利用SNA构建关联网络计算风险度量;结合复杂社会网络可达性分析与N-K模型修正出接近中心度以确定关键风险因素,并提出相关对策措施.结果表明:避免人-设-环-管多因素风险耦合形式是降低事故发生概率的关键方式;设-环-管三因素风险耦合形式最易引起事故的发生;人才队伍、管理执行力度、规章制度、文化水平、专业技能是需要重点防范的关键风险因素.
Abstract
The fusion risk factor analysis system of complex social network(SNA)and N-K model was in-troduced into the safety risk assessment of hydrogen energy storage and transportation system.Through col-lecting hydrogen energy storage and transportation accidents in the past 20 years at home and abroad,mak-ing use of N-K model calculate risk coupling values and determine accident coupling forms,and employing the SNA to construct correlation network to calculate risk measurement,as well as combining SNA reacha-bility analysis with and N-K model,The closeness centrality was modified to determine key risk factors and relevant countermeasures were presented.The results show that,reducing probability of accidents can avoid multi-factor risk coupling form of operator-device-environment-management which cause accidents most likely.Talent team,management strength,rules and regulations,cultural level and professional skills become key risk factors that need to be focused on prevention.
