A Cooperative Optimal Allocation Method of Route Slots and Levels

Abstract

The invention discloses a route time slot and altitude level collaborative optimization allocation method, which belongs to the field of air traffic management. This method first obtains the planned route and alternative route information in the flow-constrained airspace, the available time slot information of the downstream airspace unit of the planned route, and the flight operation information, and then formulates an algorithm for the collaborative optimization of the route time slot and altitude allocation. The goal of minimizing the total ground delay loss of flights, the minimum number of level changes of all flights, and the minimum total fuel consumption of all flights is to establish an objective function and constraint conditions that satisfy the effectiveness, and then establish a multi-objective optimization model for the collaborative allocation of route slots and altitude levels , and finally solve the model to obtain a non-inferior solution set, and form a collaborative optimization allocation strategy for route slots and altitude layers. The invention provides a technical basis for air traffic flow management, air space and flow collaborative management.

Description

technical field [0001] The invention belongs to the field of air traffic management, and in particular relates to a four-dimensional trajectory-based route flow management implementation method applicable to airspace management. Background technique [0002] Improving operations through free choice of routes is one of the key stages of the efficiency improvement area 3 "optimized capacity and flexible flight" in ICAO's "Aviation System Block Upgrade Program", the core idea of ​​which is to allow changes in planned routes to make full use of airspace resources, meet the needs of the optimal flight trajectory, and improve the efficiency of route flow management. Route time slot resource allocation is a key technology of route flow management. Generally, in view of the limited capacity of the planned route and the situation of available routes, according to the flight delay cost, route capacity and other conditions, the route time slot resources are allocated collaboratively, a...

Problems solved by technology

[0004] Existing studies rarely consider the allocation of altitude levels. Altitude levels have a greater impact on the fuel consumption of different types of flights, and are also an important indicator of optimal flight trajectories. The routes, their altitude levels, and time slots are allocated cooperatively, in different forms Express the flexible flight efficiency under route flow management, take into account the needs of air traffic control, airlines and other related parties, establish multiple optimization goals, and provide multiple allocation strategies for decision makers to choose from

At present, there is still a lack of a route slot and altitude level collaborative optimization allocation method
