摘要
逻辑诊断,特别是事故树分析(FTA),近年来已在国民经济各个领域得到广泛的应用.为了采用计算机辅助分析(CAA)和辅助设计(CAD)方法对事故系统进行分析与综合,首先必须获取系统的优化模型.本文研究了由人—机构成的事故系统,提出了轨迹交汇原理,完善了轨迹交汇模型.该原理与模型在安全分析、安全评价、安全预测、安全设计中具有应用价值.
The logic diagnosis,especially,the fault tree analysis,has been playing art important part in national economy.In order to utilize computer aided analysis and design in analysis and synthesis of accident system,a mathematical model is of great use.This paper deals with the Human-Machine accident system,giving the principle of the lous cross and the model of the accident system in the safety system engineering.The principle and model are applica- ble to safety analysis,safety assessment,safety forecast and safety design.
