Alarm systems play critically important roles for the safe and efficient operation of modern
industrial plants. However, most existing industrial alarm systems suffer from poor …

In modern industrial plants with a variety of interconnected devices and control loops, a fault
may propagate through the information and material flow pathways. Alarms are indicators of …

In order to be prepared for future challenges facing the industrial production domain, Cyber-
Physical Production Systems (CPPS) consisting of intelligent entities which collaborate and …

During an alarm flood, the alarm rate is greater than the operator can effectively manage.
Many alarm data analysis methods have been proposed in the literature to mitigate the …

Similar alarm sequence alignment algorithms have been used to find similar alarm floods in
the historical database for the prediction and prevention of alarm floods. However, the …

A method is proposed to analyze cause-effect relationships among binary-valued alarm
variables. A normalized transfer entropy (NTE) and a normalized direct transfer entropy …

Process abnormalities can result in serious accidents that may lead to unexpected loss of
life and property. Early fault detection and diagnosis are essential to prevent these …

A fault-isolation method based on pattern matching using the alarm lists raised by the
SCADA system during an alarm flood is proposed. A training set composed of faults is used …

In large-scale industrial plants, alarm management system (AMS) has a critical role in safety
and efficiency of the plant. High degree of connectivity in large-scale plants results in high …

An alarm management system with the Human Machine Interface in a process control
system is used to alert an operator of any abnormal situation, so that corrective action can be …
