To address the loss of cabin crew due to unfair scheduling, in order to reduce the complexity of the scheduling problem, a task ring that conforms to the basic rules of flight operation was generated, and on the basis of which three factors of flight hours, too early and too late flights, and the number of cabin crew members were simultaneously considered to establish a mathematical model of fairness scheduling, and solve it by using a genetic algorithm. Comparing the results under the two schemes of cabin crew random scheduling and fairness model scheduling, it is found that the variance of the optimized cabin crew fairness scheduling model is smaller, and the model is effective in providing a fairer solution for cabin crew scheduling.
