Study on emergency resource allocation in chemical parks considering domino effect
This paper delves into a series of studies regarding quantitative risk assessment,the siting of emergency facilities,and the deployment of emergency resources in chemical parks.Firstly,focusing on fixed hazard sources of hazardous chemicals in the chemical industry park,this study describes the risk arising from such sources as a function of accident probability and the severity of its consequences,establishing a quantitative model.Utilizing this model,a method and process for quantitative risk assessment considering the domino effect are developed,alongside an enhanced Monte Carlo simulation method to estimate accident probability.The quantitative risk assessment results indicate that the domino effect can markedly elevate the regional risk level associated with stationary hazard source accidents involving hazardous chemicals.Secondly,leveraging the quantitative risk assessment outcomes,this paper formulates an emergency facility location model with optimization objectives aimed at minimizing the overall cost of facility construction while maximizing the total risk coverage of the facilities.The model incorporates the intensity of emergency demand by constructing an emergency demand level that describes the intensity,utilizing the classification index of major danger source identification method.The solution is devised using a weighted linear combination method and an augmentation-constraint method.Additionally,the TOPSIS method is employed to optimize the decision scheme.Finally,the problem of emergency resource allocation is addressed in two stages.The first stage involves the route planning of emergency rescue vehicles.Considering the risk factors associated with vehicles during driving,this study establishes a route planning method for emergency rescue vehicles that takes into account the risk distribution of the domino effect.It proposes a route search method called Dijkstra-Domino Effect Risk,which is based on cumulative risk value.The second stage involves the scheduling of emergency resources,aiming to prioritize the earliest commencement of emergency rescue activities,optimize the allocation of various emergency resources,and minimize the number of emergency rescue points required.The emergency resource scheduling model offers tailored scheduling schemes based on the varied decision preferences of managers.
