故障树综合是故障树分析的基础,也是风险分析的有力工具。传统的人工构建故障树的方法费时费力,且易受人为错误的影响,因此计算机辅助故障树合成已成为系统安全工程领域的一个发展趋势。本文阐述了一种应用决策矩阵方法开发的过程工业故障树综合信息系统(FTSIS)。该系统将目标系统分解为一系列的系统部件,建立各部件的因果模型,并将其存储在关系数据库中,转化为决策矩阵。在FTSIS中对决策矩阵进行充分搜索后,自动生成故障树,成功实施后,验证了该方法的有效性。
Fault trees synthesis, the basis for fault tree analysis (FTA), serves as a powerful tool for risk analysis. It has become a trend to accomplish computer-assisted fault tree synthesis in the field of system safety engineering because conventional manual construction of fault trees can be extremely time-consuming and vulnerable to human errors. This paper expounds upon a fault tree synthesis information system (FTSIS) developed by means of decision matrix for the purpose of its application to process plants, where the objective system is decomposed into a series of system components whose cause-effect models are constructed and stored in the relational database and transferred into decision matrix. The fault tree is synthesized automatically after the decision matrix is fully searched in FTSIS, the availability of which has been verified after it was put into effect successfully.
