Regional collaborative allocation of emergency resources for enterprises within a chemical industry park based on the worst credible accident scenarios

Abstract

Emergency resources play a vital role in the emergency rescue process. The adequate and timely supply of emergency resources can effectively control the development of accidents and reduce accident losses. However, the current emergency resource allocation of chemical enterprises lacks scientific analysis of accident scenarios, and the individual allocation method of enterprises increases the cost of emergency resource allocation. Given the above problems, this paper proposes a regional collaborative allocation method of emergency resources for enterprises within the chemical industry park (CIP) based on the worst credible accident scenario (WCAS). Firstly, the concept and analysis method of the WCAS is proposed. Then, based on the characteristics and consequences of the accident, the mapping relationship between accident scenarios and emergency resources is established. Finally, an optimization model for regional collaborative allocation of emergency resources is constructed to determine the amount of emergency resource allocation for each enterprise. Through the case study, the emergency resource allocation method based on the WCAS analysis can better meet the demands of accident emergency rescue. Simultaneously, the regional collaborative allocation optimization model can strengthen the cooperation ability among enterprises, greatly reducing the cost of emergency resource allocation for each enterprise.
