Design method of plant alarm systems on the basis of two-layer cause-effect model

Abstract

In the recent years, there has been an increase in the number of accidents involving chemical and industrial plants. In most of the cases, the inadequate performance of alarm system has become a significant cause of industrial incidents and serious accidents. In general, alarm systems design can be divided into two processes, which are selecting alarm source signal and determining alarm limit. Authors have proposed the alarm source signal selection method. In this paper, we would like to focus on how to determine alarm limit using statistical method and evaluate this alarm design method through study case. © 2011 Springer-Verlag.
