Abstract

To assess performance of a plant´s alarm system, it is necessary to evaluate various performances indices. False alarm rates, missed alarm rates and detection delays are considered as important performance measures for univariate alarm design. To reduce false and nuisance alarms, filtering is widely used in industries. However there has been very limited study on performance specifications of various filtering methods, and the quantitative relation between filter properties and these performance indices are not well known. In this paper we investigate the effect of filtering on detection delay as an important alarm performance index.
