Abstract:The essence of flight scheduling planning is to optimize the factors in product ion process. It has a direct impact on the airline market competitiveness. Curre ntly, in the planning of short-term flight scheduling, the market competition i s considered too much, while the delays are ignored. Flight delay control is in corporated into the layout process of short-term flight scheduling planning, co nsidering the market competition and flight delays. By analyzing the characteristics of independent delay and propagation delay, a planning model for short-term flight scheduling is built based on delay control strategy. And the model is solved by using the greedy randomized adaptive search procedure (GRASP) algorithm. Finally, the effectiveness of the model is verified by instance analysis.
