For acceptable performance of an alarm system for a mulitmode process, it is inevitable to
have appropriate alarm configurations for every mode of the process. Delay-timers, being …

Pipelines are among the principal means of transporting hydrocarbon fluids and gases, so
leakage detection is critical to avoid the loss of these energy resources. In this article, based …

In process plants, alarms are configured to notify operators of any abnormalities or faults.
However, in practice a majority of raised alarms are false or nuisance and create problems …

Deadbands are widely used in industries due to their ease in configuration, and
effectiveness in reducing false and nuisance alarms. An effective design of a deadband …

In the process industry, process variables are continuously monitored to ensure safety,
reliability and efficiency of plant operations. Due to the advancement of the modern …

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 …

The effectiveness of industrial process monitoring depends heavily on alarm systems. If
alarm configurations are not rationally designed, the problem of excessive alarm messages …

Nowadays, leakage detection is of great importance as pipelines are the major means of
transporting hydrocarbon fluids and gases. In this thesis, we propose two methods based on …

In process plants, alarms are configured to notify operators of any abnormalities or faults. In
practice, operators receive far more false and nuisance alarms than valid and useful alarms …
