Emergency Vehicle Dispatching for Railway Dangerous Goods Accidents Based on the Cooperative Game Theory

Transport of dangerous goods via railway is quite complicated as there are many uncertain factors that can threaten the security of such operations. A limited supply of emergency vehicles must be dispatched effectively in the event of a railway dangerous goods accident in order to minimize losses. Therefore, a multi-objective model of emergency vehicle dispatching for railway dangerous goods accidents is established. The model considers the minimum time for rescue, the minimum losses due to the accident, and the lowest cost as the objectives. Meanwhile, cooperative game theory is used by regarding each goal as a player and all possible emergency vehicle dispatching schemes as the strategy set. The optimal emergency vehicle dispatching scheme is proposed by solving the cooperative game model, which considers the players’ profit equilibrium and an overall high return. Finally, an example is given to test the model feasibility and effectiveness of the algorithm.
