Temporal assessment of emergency response and rescue capability for hybrid hydrogen-gasoline fueling stations based on dynamic scenario construction

Abstract

In the event of a fire or explosion at a hybrid hydrogen-gasoline fueling station, the consequences can be significantly more severe compared to a traditional refueling station or hydrogen refueling station. It is imperative to establish an effective assessment model specific to the hybrid station to prevent and mitigate such accidents. This paper introduces a temporal dynamic assessment model designed to evaluate the emergency response and rescue capabilities of hybrid hydrogen-gasoline fueling stations. The model is grounded in dynamic scenario construction and utilizes information-driven theory. This innovative approach allows for evaluations of the risk evolution process at different stages of an accident. The proposed assessment model combines the Temporal Weighted Average (TOWA) and Temporal Weighted Geometric Average (TOWGA) operators to integrate assessment values across different stages including the initial disaster assessment, emergency action plans, effectiveness feedback, and emergency response adjustment. This integration yields a comprehensive dynamic assessment value for the emergency response and rescue capabilities of the hybrid hydrogen-gasoline fueling station. Based on the dynamic assessment of a previously occurring accident, the specialized emergency management department performed most effectively during the incident response stage, achieving a commendable assessment value of 3.184. Following closely was the government emergency response department, with assessment values of 2.865 and 2.277. This study offers a novel analytical perspective for emergency management in hybrid hydrogen-gasoline fueling stations by incorporating the findings of both dynamic and static assessments.
