【摘要】：为给事故预防与调查提供有效方法和依据,运用信息科学与安全科学方法,开展多级安全信息不对称所致事故模式研究。基于信息流动的一般模型,构建安全系统中安全信息流动的一般模型;分析安全系统中引发安全信息不对称的因素,并构建"信源-预测-决策-执行"多级安全信息不对称的事故致因模式;根据事故案例,分析验证多级安全信息不对称的事故致因模式的可行性和可靠性。结果表明:多级安全信息不对称的事故致因模式主要包括"真信源—安全信源"信息不对称、"安全信源—安全信宿"信息不对称和"安全信宿—安全信宿"信息不对称等3种事故致因模式,且具有充分的实用性与可行性。
[Abstract]:In order to provide effective method and basis for accident prevention and investigation, the accident mode caused by multi-level safety information asymmetry is studied by means of information science and safety science. Based on the general model of information flow, the general model of security information flow in security system is constructed. The factors causing asymmetry of safety information in safety system are analyzed, and the accident cause mode of "source-prediction-decision-making-execution" multi-level safety information asymmetry is constructed. According to the accident cases, the feasibility and reliability of the multi-level safety information asymmetry accident-induced mode are analyzed and verified. The results show that the accident cause mode of multilevel security information asymmetry mainly includes "true source-secure source" information asymmetry. The information asymmetry of "safe source-safe destination" and "safe source-safe destination" information are three kinds of accident-causing modes, which have sufficient practicability and feasibility.
