Abstract

False and nuisance alarms are major problems in the process industry. Generalized delay-timer is an effective technique to improve the performance of an alarm system. However, due to the increasing intermediate states, computation of the performance indices, false alarm rate (FAR), missed alarm rate (MAR) and expected detection delay (EDD), is hard and unsolved for generalized delay-timer. In this paper, we first propose a general formula to compute FAR and MAR by adequately reconsidering the internal relationship between the no-alarm state and the alarm state for generalized delay timer. Then the computation of EDD is discussed via the probability of alarm or no-alarm at samples by iteration.
