集成化SDG建模、推理与信息处理软件平台

过程工业的安全问题正日益引起公众及政府的关注和担忧。大量的人力物力被投入到过程风险评价(PHA)中，而它们的大多数依靠人工完成。近年来，通过引入符号有向图(SDG)，基于计算机的自动PHA成为了可能。这项工作的首要任务是建立一个实用的SDG建模、推理平台。我们基于对HAZOP评价方法的研究，根据操作的步骤和需要，最终设计、开发了一个图形化、层次化、支持组件可复用的SDG软件平台，以供建模、推理和数据后处理使用。该平台基于自主开发的SDG推理引擎和图形建模环境，其设计充分考虑技术研究的持续和渐进性，利用迭代开发和面向对象的技术，支持多种算法的混合使用和组件的复用，从而在SDG的图形建模、推理引擎构架和双向推理方面做出了有益的探索。

Integrated SDG Modeling, Inference and Post-Processing Software Platform

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.
