Optimization of enterprise emergency material dispatch considering the third-party emergency force

The third-party emergency forces such as neighboring enterprises in the accident can improve the rescue efficiency and shorten the rescue time to ensure the production and property safety of the affected people as much as possible. This paper proposes an emergency material scheduling model taking time as the objective and considering the participation of multi-party emergency forces. The model can freely decide the type of materials to improve the rescue efficiency when the risk index of the accident point is satisfied. A real case illustrates the applicability of the proposed model. The result shows that the average arrival time of emergency supplies for corporate safety production accidents is 12.53 minutes, of which 89.13% of accidents can deliver supplies within 10 minutes. Daishan Fire Brigade and CNOOC (Zhoushan) are the main rescue partners for enterprises. In addition, foam trucks are given priority to be put into the rescue process. This study can provide a basis for enterprises to adjust the storage of materials and the government to supervise enterprises.
