Research on safety resilience evaluation of gastransmission pipelines in chemical industry parks

Gas transmission pipelines within chemical industrial parks operate in complex environments with elevated risk profiles, where potential leaks or explosions could trigger cascading consequences including operational disruptions, critical infrastructure failures and severe environmental and safety implications. Consequently, this study develops a systematic safety resilience assessment framework for gas transmission pipelines in chemical industrial parks, integrating system dynamics simulation methodologies. A comprehensive complex network model is established to identify and analyze critical factors influencing pipeline safety resilience. The proposed evaluation framework incorporates a multidimensional index system encompassing resistance, recovery and adaptability capacities. By integrating techniques such as quadratic exponential smoothing, grey system theory and system dynamics simulation, the safety resilience characteristics of gas transmission pipelines are quantitatively evaluated and predicted. The analytical results provide valuable insights into the evolutionary trends of resistance, recovery, adaptability and overall system resilience of gas transmission infrastructure. The findings offer critical insights for ensuring the safe operation of gas transmission pipelines and enhancing the overall resilience of chemical industry parks.
