Due to the uncertainty of risk occurrence and the severity of accident consequences in the process of hazardous chemical storage, there are many stakeholders involved in the management and supervision of hazardous chemical storage, and their interest appeals are different. On the basis of ensuring storage safety, in order to balance the interests of stakeholders and achieve cooperative operation, a two-level programming model considering the maximization of social welfare and the interests of warehousing enterprises was proposed. First, the upper model mainly refers to the regulatory department represented by the government, including the daily supervision cost, risk loss cost, risk compensation cost, and penalty coefficient formulated by combining various indicators. In the lower model, the comprehensive risk level of the warehouse is determined by the warehouse enterprise. Based on this, the supervision coefficient is determined. Combined with the punishment coefficient, the warehousing operation cost, warehousing supervision cost, and the punishment cost when the accident occurs under different risk levels are determined. The relevant case analysis shows that, compared with the evolutionary game model, the social supervision cost of the upper level and the enterprise cost of the lower level can be reduced by 0.49% and 30.43% respectively. Compared with the traditional improved particle swarm optimization algorithm, the proposed algorithm can reduce the supervision cost of the upper society and the lower enterprise by 0.11% and 7.05%, respectively, thus achieving a better supervision effect at a relatively low cost. |
