摘要
分析了符号定向图(SignedDirectedGraph,SDG)技术在危险与可操作性分析(HAZardandOPerability,HAZOP)、过程危险性分析(ProcessHazardAnalysis,PHA)等领域中的应用现状和前景,提出了研究基于SDG的HAZOP计算机辅助自动建模方法,构建了基于SDG的HAZOP计算机辅助自动建模软件平台,阐述了研究路线,展示了应用策略。软件平台构建的研究填补了国内在SDG自动建模领域的研究空白,拓展了计算机辅助设计(CAD)技术和符号定向图(SDG)技术在复杂系统重大事故及智能诊断领域的应用。
The actuality and foreground of SDG (signed directed graph) applied in the field of HAZOP (HAZard and OPerability) and PHA (process hazard analysis) are analyzed. The method of HAZOP models established automatically is put forward based on SDG. The task is to develop a software based on the method. There are the investigative route and applied strategy. This study and the software platform have not be down in domestic now. This study will accelerate the application of the method of CAD and SDG in fault diagnosis realm.
