Calculation method of comprehensive strategy for cross-regional tailing interval restriction and departure slot allocation

Abstract

The present invention relates to the field of aviation, and specifically relates to a method for calculating a comprehensive strategy for cross-regional trailing interval restriction and departure time slot allocation. By constructing a cross-regional trailing interval restriction and departure time slot allocation mixed integer programming model and solving it, the Calculate the cross-regional tailing interval limit and the comprehensive strategy for the allocation of departure time slots. Generated for the constraints imposed by the flow control point of the flight in the downstream exit area MIT The tailing interval restriction strategy of the controlled flight entering the regional flow control point upstream and the calculation take-off slot strategy of the flight with limited take-off slot inside and outside the area, based on the analysis of the operational restrictions and optimization goals in the implementation management, and the calculation of the take-off slot Based on the analysis of the implementation characteristics of the trailing interval restriction, a mixed integer programming model was established and solved. It was found that considering the trailing interval restriction and departure slot allocation is more efficient than the traditional first-come-first-serve management, and reduces the overall flight delay cost.

Description

technical field [0001] The present invention relates to the field of aviation, in particular to a method and system for calculating a comprehensive strategy for regional trailing interval limitation and departure time slot allocation. Background technique [0002] When the downstream outbound area points are subject to external flow control, in order to solve the problem that the downstream trailing interval is amplified and propagated upstream, causing upstream flights to be subject to excessive flow control restrictions, a collaborative management program for trailing interval restrictions and take-off and departure time slots is established. Flights affected by flow control at regional points are managed by trailing interval and departure slot allocation strategies respectively. The traditional first-come-first-serve management strategy allocates passing time slots according to the order in which they plan to arrive at the downstream point, and usually does not take into ...

Problems solved by technology

The traditional first-come-first-serve management strategy allocates passing time slots according to the order in which they plan to arrive at the downstream point, and usually does not take into account the delay cost of the flight. In addition, the traditional trailing interval management strategy does not consider the specific distribution of traffic flow, so the calculation The upstream trailing interval is too extensive, causing a lot of unnecessary delays to flights
