Computational method of cross-region trailing interval restriction and departure slot assignment

Abstract

The invention relates to the aviation field, in particular to a cross-region trailing interval restriction and departure time slot allocation comprehensive strategy calculation method, which calculates the cross-region trailing interval restriction and departure time slot allocation comprehensive strategy by constructing a cross-region trailing interval restriction and departure time slot allocation mixed integer programming model and solving the model. Aiming at the constraint of flight departure flow control point in downstream area, the trailing interval restriction strategy of MIT controlled flight in upstream area flow control point and the computational departure slot restriction strategy of departure slot in and out of area are generated, based on the analysis of operation restriction and optimization objective in implementation management, the mixed integer programming model is established and solved by analyzing the implementation characteristics of computing departure slot and trailing interval constraints. It is found that the integrated consideration of trailing interval constraints and departure slot allocation is more efficient than the traditional first-come-first-served management, which 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
