| Summary: | In order to scientifically and rationally assess the safety condition of coal mine production logistics system, this paper establishes a risk assessment model of coal mine production logistics system based on BWM-Vague set. On the basis of reviewing a large amount of literature and combining the main contributing factors of coal mine production safety accidents in practice, a relatively complete set of safety evaluation index system for coal mine production and logistics system was established, including 4 primary indexes of personnel safety, machine and equipment safety, environmental safety and management safety, and 16 secondary indexes such as the proportion of professional and technical personnel, and the fuzzy comprehensive evaluation method was applied to evaluate the index system. Firstly, the BWM assignment method is used to determine the weights of each index, after which Vague set theory is introduced and experts are invited to evaluate and score each index, and then the two are combined to determine the final comprehensive evaluation. Finally, the model was empirically tested in the context of a coal mine enterprise in Beijing, with a view to improving the safety of the production logistics system in coal mines.
