Slot switching model of airlines under cooperative game

Aiming at the ground holding problem under the operation mode of flight bank,slot switching strategy was proposed.The minimum passenger delays of all airlines involved in slot switching were taken as objective functions,the Pareto improved solution was taken as constraint condition,and the slot switching model between two airlines was established by using cooperative game theory.The model was decomposed into slot assignment model and slot combination model.By using slot assignment model,the optimal assignment scheme and objective function value under determined slot condition were obtained.By using slot combination model,the optimal slot allocation schemes of two airlines were obtained.Computation result shows that without slot switching,the total passenger delays of airlines 1 and 2 are 238 955,145 170 min respectively.After switching six slots between two airlines,the total passenger delays of airlines 1 and 2 are 232 945,142 130 min respectively,and reduce by 2.5% and 2.1% respectively.When flight information is complete,slot switching can make airlines get optimal Pareto improved solutions.When flight information is imcomplete,airlines can obtain better slot switching schemes by using bargaining method.
