Abstract

Abstract: Alarm systems as the primary means for improving safety performances and maintaining reliable operations for industrial processes have been playing a significant role in practice. However, there exist many problems in practical applications with conventional alarm systems. Industrial accidents may occur because operators cannot handle abnormal events due to inefficient alarm systems. Motivated by these observations, this article discusses assessment of alarm systems in the management lifecycle. The paper conducts a detailed analysis for the common problems, causes and possible consequences of current industrial process alarm systems, as well as constructing an evaluation framework of alarm systems reasonable and efficient combined alarm system characteristics and parameters. Based on this framework, a quantitative assessment method is introduced, which can enjoy some advantages such as accessing data easily, implementing conveniently, and facilitating understanding for operators and managers.

Key words: alarm system assessment, quantitative assessment method, false alarm rate, missed alarm rate, averaged alarm delay

摘要： 流程工业报警系统通过报警信息显示当前过程存在的异常情况,提醒操作员及时干预以避免生产事故,其运行效率和流程工业的安全性能密切相关.报警系统效率低下会严重影响流程工业安全经济运行,然而报警系统优化与再设计的过程复杂,耗费大量人力物力,并且可能影响整个生产过程的正常运行.报警系统是否需要重新优化、何时优化、优化方向等问题困扰着工程研究人员,需要对其进行正确的评估.针对评价流程工业报警系统的常用定性指标进行机理分析,指出对于报警系统运行效率影响较大的几个因素,在此基础上构建了量化评估报警系统效率的指标,评估指标可以使工程研究人员更为直观地了解报警系统运行效率及其对于流程工业的影响,辅助优化报警系统.
