Abstract:

Fleet assignment is one of the most important problems in airline resource optimization and management, which affects the profitability and competitiveness greatly. In order to solve the singularity of existing fleet assignment methods, a multi-objective fleet assignment model is proposed based on traditional fleet assignment models,which means that taking profit maximization and least number of aircraft as optimizational targets. However, complicated multi-objective solving model can bring bias target solving. NSGA-II algorithm is used to solve the multiobjective problem. The instance verifies the effectiveness of this method. Compared with single-objective optimization for fleet assignment model, experiment shows that the result solved by the proposed model can reach more even distribution and provide reference for decision making of airline fleet assignment.

Key words: air transportation, fleet assignment, NSGA-II algorithm, multi-objective optimization, flights
