Cost control model of marine crude oil pollutant degradation based on game analysis.

In the process of exploration, exploitation, and transportation of offshore oil, it is easy to cause leakage accidents due to bad environment, aging facilities, and violent collision. The existence of a large number of offshore oil spills has seriously affected the marine ecological environment; the treatment of crude oil pollutants not only has a very long treatment cycle, but also its treatment cost is immeasurable. In order to clarify the cost allocation of marine crude oil pollutants, this study constructs the cost allocation model of offshore crude oil based on game theory. Based on the characteristics of crude oil diffusion and the tidal current field model of the leakage sea area, the influence area of crude oil diffusion is analyzed, and the crude oil leakage diffusion model is constructed. Based on the Shapley value method, this paper constructs the cost allocation model of the tripartite game subject, and analyzes its stability and fairness. The results show that the fair index of Shapley method is 0.507, and the split index of the three subjects is 0.688, 0785, and 0.011.This model can ensure the fairness of cost allocation on the premise of ensuring the stability of the cooperative alliance. The crude oil diffusion model and cost allocation model constructed in this study will have certain guiding significance for compensation allocation in crude oil leakage. [ABSTRACT FROM AUTHOR]
