工艺安全问题已经引起了公众越来越多的关注和担忧。在过程危害分析（PHA）中投入了大量的人力和物力，其中大部分是人工进行的。近年来，通过引入SDG，基于计算机的自动PHA成为现实。在这个过程中，最重要的任务是创建一个实用的SDG建模和推理平台。本文介绍了本实验室在流程工业安全分析研究方面的进展。在对HAZOP（危险可操作性）分析研究的基础上，根据HAZOP分析的步骤和要求，设计并开发了一个基于图的、分层结构的、构件可重用的软件集成平台。该平台基于自主开发的SDG引擎和图形建模环境，充分考虑了SDG研究的进展，采用了多种迭代开发技术和面向对象编程（OOP）技术。在这个平台中，各种算法可以一起使用，它们的组件可以很容易地重用。为SDG图建模、推理机结构和双向推理提供了一个良好的开端。
Process safety issues have caused ever-increasing public concern and worry. Enormous labour and material resources have been invested in Process Hazard Analysis (PHA), most of which are carried out manually. Recently, by importing SDG, the automatic computer based PHA becomes practical. During the process, the most important task is to create a practical SDG platform for modeling and inference. In this paper, we discuss the progress in our laboratory on safety analysis research for process industry. Based on research in HAZOP (Hazard Operability) analysis and according to its steps and requirements, we have designed and developed a graph based, layered structured and components reusable software integrated platform. This platform, which is based on a SDG Engine and a graphic modeling environment developed by ourselves, fully considers progress of SDG research, and uses a variety of iterative development technique and object orient programming (OOP). Within this platform, various algorithms can be used together and their components can be easily reused. It is a good start for SDG graph modeling, inference engine structure and dual direction inference.
