摘　　要：传统的设备管理模式造成设备非计划停机次数较多、故障频繁、可靠性和可用性不高等问题。为了解决上述问题,开发了成套装置动态风险管理专家系统,该系统包括动态风险监控、数据存储、失效模式及损伤机理判别、动态风险评估、风险辅助分析5个流程。该系统通过GIS平台进行展示,使用户可以直观、方便地查找、定位管线和容器位置,实现了高风险设备的风险展示、管道剩余寿命不足报警功能和管道冲蚀图例展示。将该专家系统进行了工程应用,得到容器和管道的潜在损伤机及其风险等级,针对不同风险等级的设备,生成了不同的检维修策略,为工程应用带来了很大的方便。The traditional equipment maintenance and security management methods, such as multi-inspection, multi-repair, multi-maintenance and repair after failure, are still the main stream in Chinese petrochemical enterprises. Thus, there are many unplanned shutdowns of equipments and failures of equipments, which have a great impact on the petrochemical industrial safety, environmental and economic loss. The equipment reliability and a- vailability is not good. To solve the above problems, an expert system for dynamic risk management of complete set of equipments was developed. The system has five processes, including risk monitoring, data storage, failure mode and discrimination of damage mechanism, dynamic risk assessment, and risk auxiliary analysis. An engineering ap- plication was carried out for the expert system. The potential damage mechanism and risk rating of the pressure ves- sel and piping were obtained. The different inspection maintenance strategies for different risk pressure vessel and piping were generated automatically. The system has brought a convenience for the equipment management in an enterprise.
