G2实时智能软件是一种在线专家系统开发工具。论述了如何利用G2软件进行加氢裂化工艺在线专家指导系统的开发过程 ,以加氢裂化工艺为应用对象建立了类层、工作空间层次和模块化层次 ,对知识库的建立以及知识的获取和知识的表示作了说明 ,以加热炉为例建立了部分模拟规则。开发的加氢裂化工艺在线指导系统 ,保存了各种加氢裂化工艺技术知识和专家们的宝贵经验 ,为操作员实时提供正确的指导信息 ,可改进生产过程控制和管理 ,优化生产操作 ,提高产品质量 。

The G2 real-time intelligence software is a developing tool for on-line expert system. The process how to develop on-line expert guide system with the G2 real-time intelligence software was introduced. With the hydrocracking process as the application object the class hierarchy, working space level and module level were established. Building of knowledge base, acquisition of knowledge and representation of knowledge were discussed. Part emulation rules was set up by taking furnace as example. The developed on-line expert guide system for the hydrocracking process stores the knowledge of every kind of hydrocracking process technique and the precious experience of experts. Thus it can offer the operators right guide information, improve the production process control and management, and optimize production operation, increase product quantity, reduce cost.
