ETA是一种逻辑的演绎法,是安全分析的方法之一。它常用于安全系统的事故分析和系统的可靠性分析。一起伤亡事故的发生,是许多事件按时间顺序相继出现的结果。其中,一些事件的出现是以另一些事件首先发生为条件的。描述事故发展逻辑次序可以通过“事件树”来实现。
ETA is a logical deduction, which is one of the methods of safety analysis. It is commonly used in accident analysis of safety systems and reliability analysis of systems. The occurrence of a casualty is the result of successive occurrences of many events in chronological order. Among them, the emergence of some events is based on the occurrence of other events first. The logical sequence describing the development of an incident can be achieved through “Event Tree ”.
