安全系统工程是20世纪后半叶系统工程发展最快的分支学科之一,事故树分析则是安全系统工程最重要的分析方法之一,该方法具有描述事故因果关系直观、明了,思路清晰,逻辑性强的特点,能对各种系统的危险性进行定性和定量的辨识和评价.作者针对传统事故树分析方法的不足,提出了基于可视化理论和技术的事故树可视化模型,并进行了系统的初步开发,确定了系统功能目标,完成了系统结构设计,构造了事故树图形生成与事故树动态分析于一体的集成分析环境,为事故分析和系统安全评价提供高效准确的新方法.图6,参6.
Safety system engineering is one of the fastest growing branch systems in the second half of the 20th century. Fault tree analysis is one of the most important analysis methods in safety system engineering. It has the characteristics of describing the causal relationship of accidents as being intuitive, clear and clear, Which can logically and quantitatively identify and evaluate the danger of various systems.According to the deficiency of traditional fault tree analysis methods, the author presents an accident tree visualization model based on visualization theory and technology and carries out a systematic Of the initial development, to determine the system functional goals, completed the system structure design, construction of the accident tree tree and dynamic analysis of the accident tree in one integrated analysis environment, for accident analysis and system safety evaluation with high efficiency and accuracy of the new method Figure 6 Participation 6.
