Performance analysis of safety instrumented systems against cascading failure during prolonged demand
Xie, Lin; Lundteigen, Mary Ann; Liu, Yiliu (Peer reviewed; Journal article, 2021)Cascading failures may occur in many technical systems where the failure of one component triggers successive events. Safety barriers like safety instrumented systems are installed in many industries to prevent failures ... -
Performance assessment of K-out-of-N safety instrumented systems subject to cascading failures
Xie, Lin; Lundteigen, Mary Ann; Liu, Yiliu (Peer reviewed; Journal article, 2021)Safety instrumented systems often employ redundancy to enhance the ability to detect and respond to hazardous events. The use of redundancy increases the fault tolerance to single failure but remains vulnerable in case of ... -
