【摘要】：诠释了生产执行制造系统(MES)智能化的内涵,提出了石化MES智能化功能提升方案,阐明提升应包括功能层及平台层中已有功能提升和新功能构建及功能集成。本文重点介绍了平台层中的工厂模型提升、智能计算服务环境和事件服务中心这三大智能支撑功能的提升。采用基于面向对象分析方法的工厂模型扩展方法,实现了现有工厂模型提升。通过问题求解算法选型及组件封装,实现了智能计算服务环境的构建。在介绍事件服务中心总体架构的基础上,分别阐述了为了实现复杂事件检测和专家知识库两大核心功能所解决的复杂事件匹配模型和专家规则引擎的构建等关键问题。依据所提出的集成方案,将三大提升功能集成于现有MES平台之中,实现了平台功能提升。最后介绍了为实现某炼化企业乙烯装置节能降耗和安全生产所进行的MES智能化功能提升、实际应用效果及经济效益。
[Abstract]:This paper explains the connotation of intelligent production execution manufacturing system (mes), and puts forward an intelligent function upgrading scheme for petrochemical MES. It is clarified that the promotion should include the existing function enhancement and the new function construction and function integration in the functional layer and platform layer. This paper focuses on the promotion of factory model in the platform layer. The intelligent computing service environment and event service center are the three main functions of intelligent support. The factory model extension method based on object-oriented analysis is adopted. Through problem solving algorithm selection and component encapsulation, the intelligent computing service environment is constructed. The overall architecture of event service center is introduced. In order to realize the two core functions of complex event detection and expert knowledge base, the key problems such as complex event matching model and the construction of expert rule engine are expounded respectively. Integrate the three enhancements into the existing MES platform. Finally, the MES intelligent function, practical application effect and economic benefit are introduced in order to realize energy saving and consumption reduction and safety production of ethylene plant in a refinery.
