基于SDG的计算机辅助危险与可操作性分析

对于过程系统，危险与可操作性(Hazard and Operabiljty，简称HAZOP)分析是一套应用最广的评价方法。但是人工评价存在费时、费力、成本高等缺点。本文介绍了一种基于SDG(Signed Directed Graph)的计算机辅助危险与可操作性分析系统，该系统基于SDG定性模型。过程模型利用模型库中的单元模型建立，通用性强，且又能分析各种具体工艺的特定信息。应用实验表明，与人工专家评价相比，该系统具有完备性好、省时、省力、成本低、评价结果系统性和条理性强等众多优点。

Computer Aided HAZOP Analysis Based on SDG

Hazard and Operability (HAZOP) analysis is widely used and recognized as the preferred safety analysis approach in the process systems. However, the manual HAZOP analysis is time consuming, strenuous and costly. A computer aided HAZOP analysis system based on SDG is introduced. SDG qualitative model is used in this system. As process model is built by unit models in the model base, the system is very adaptive. Besides, it can handle the huge amount of specific process information. Compared with the manual HAZOP analysis, the system has many advantages, such as good maturity, time saving, effort saving, money saving, systematic result, and so on.
