With digital technology, alarm systems have become complex and overwhelming for operators, resulting in disasters like Chernobyl. Therefore, it is crucial to develop reliable decision support systems.<\/p>\n<p>We draw a parallel between these alarms and constellations, which are prominent stars that stand out among millions of stars and form a specific shape. Analyzing correlated alarms from historical data, we create a visual map or &#8220;constellation of alarms&#8221; showing abnormality propagation paths. This helps to construct &#8220;pathways\u201d for better and safer process operation. In the network graph shown, each node represents an alarm, the bigger the node, the more prominent the alarm; and the arrow represent the abnormality propagation direction.<\/p>\n<p>Join us in our &#8220;star (alarm)-gazing&#8221; journey to prevent industrial disasters.<\/p><\/p>\n\n\n\n<p><\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Submission 2023 Submitted by: Harikrishna Rao Mohan Rao Department: Electrical and Computer Engineering Faculty: Engineering Looking to the stars for guidance isn&#8217;t just for sailors &#8211; it can also help prevent catastrophic disasters in chemical processes.
