Dynamic risk assessment of chemical process systems using the System-Theoretic accident model and process approach (STAMP) in combination with cascading failure propagation model (CFPM)

Sun, Hao (author), Wang, Haiqing (author), Yang, M. (author), Reniers, G.L.L.M.E. (author)

To maintain continuous production, chemical plant operators may ignore faults or handle faults online rather than shutting down process systems. However, interaction and interdependence links between components in a digitalized process system are substantial. Thus, faults will be propagated to downstream nodes, potentially leading to risk...

Dynamic Risk Assessment of Chemical Process Systems using System-Theoretic Accident Model and Process (STAMP) and Failure Propagation Model

Sun, H. (author), Wang, Haiqing (author), Yang, M. (author), Reniers, G.L.L.M.E. (author)

Chemical process systems involve complex dynamic processes, and the state of the system often fluctuates during the production process. To ensure the continuation of production, these fluctuations are often ignored or processed online instead of shutting down the unit. However, the interdependence between components in the system is strong, and...

A STAMP-based approach to quantitative resilience assessment of chemical process systems

Sun, H. (author), Wang, Haiqing (author), Yang, M. (author), Reniers, G.L.L.M.E. (author)

Chemical process systems (CPSs) involve complex dynamic processes. Besides, the emergent and uncertain hazards and disruptions cannot be identified entirely and prevented by conventional methods. In those situations, resilience for CPSs plays an essential role in absorbing, adapting to disruptions, and restoring from damages. Systemic modeling...

A virtual experiment for measuring system resilience: a case of chemical process systems

Sun, H. (author), Yang, M. (author), Wang, Haiqing (author)

Resilience is an emergent property of a system, which changes with various internal and external factors. Resilience is also a hidden property of a system that cannot be observed. Thus, experiments should be performed for a given system to measure its resilience. However, physical experiments are practically impossible. Inspired by the tensile...
