摘要

Abstract

Alarm systems play important roles for the safe and efficient operation of modern industrial plants. Critical alarms are configured with a higher priority and are safety related among many other alarms. If critical alarms can be predicted in advance

the operator will have more time to prevent them from happening. In this paper

we present a dynamic alarm prediction algorithm

which is a probabilistic model that utilizes alarm data from distributed control system

to calculate the occurrence probability of critical alarms. It accounts for the local interdependences among the alarms using the n-gram model

which occur because of the nonlinear relationships between variables. Finally

the dynamic alarm prediction algorithm is applied to an industrial case study.
