Abstract: In process industry, alarms are configured to notify operators of equipment malfunctions, process deviations, or any other abnormalities in the plant. However, unsophisticated alarm configuration may result in numerous of false alarm and nuisance alarm or even alarm floods for operators and reduce its performance as a safeguard for plant operations. In the past, many catastrophic incidents happened due to poor performance of alarm systems. Motivated by this, we first propose a new techniques which considered deadbands and delay-timers sufficiently configured in univariate alarm system. Extensive simulations are conducted to verify the analytical results and illustrate the advantages.
