A Novel Multi-objective Optimization Model for Minute-in-Trail Strategy Based on Sector Workload Restriction

Air traffic flow quantity should not exceed sector capacity. Minute-in-trail strategy can reduce the amount of aircraft into the sector by widening the separation of continuous arrival aircraft. However, the present model is not suitable for some complex sectors, because the same quantity of aircraft may cause variety of workload by the influence of traffic complexity. In this paper, a traffic flow-capacity matching model based on workload restriction is presented, the stability function for evaluating the strategy in each slot time is defined, and an evolutionary algorithm is proposed to search Pareto solutions for multi-objective optimization model with Minute-in-trail Strategy. Experimental results verify the validity of the method.
