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 enter-prises.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 .
