With the difference between the off-peak season and the occurrence of temporary emergencies, the airport will have a situation of severe shortage of personnel in a certain period when the task volume increases sharply. The studies in this paper do not entirely cover the problem of airport task assignment. The first objective function is to maximize the benefits generated by the task, and the second objective function is to minimize the sum of the differences in the level of qualifications and skills. A multi-objective integer programming model was constructed, and an improved multi-objective memetic algorithm was designed. In the process of solving the problem, the actual data were tested, and the numerical results showed that the accuracy of the built model and improved algorithm was verified compared with CPLEX optimization software. For large-scale examples, when the first objective function value is approximately optimal, the second objective function value is better than the CPLEX solution, with an average optimization of 5.89%. The sensitivity analysis of the coverage rate, shift working hours, and other parameters showed that the setting of different parameters significantly impacted the objective function. This study can not only effectively solve the problem of airport task assignment, but also provide a scientific basis for the actual operational decisions of enterprises.
