Problems solved by technology

Most current sector conflict resolution models only focus on single-sector or multi-sector conflict resolution itself, and seldom pay attention to sector conflict resolution constraints and waypoint flow management constraints at the same time, so they cannot satisfy the existing waypoint flow control in actual operation. Modeling Requirements for Conflict Detection and Resolution under Constraints

Abstract

The invention particularly relates to a multi-sector conflict detection and release model construction method and a model constructed by the method. The multi-sector conflict detection and release model construction method comprises the following steps: defining parameters involved in a mixed integer nonlinear programming model; determining a decision variable of the mixed integer nonlinear programming model; determining constraint conditions of the mixed integer nonlinear programming model according to the parameters and the decision variables; and constructing an objective function of a mixed integer nonlinear programming model, flow management and air traffic control actual operation constraints can be considered at the same time according to constraint conditions, and the influence ofa conflict resolution strategy on flight operation and control workloads is comprehensively considered for an optimization objective of the model. Decision objects of the model cover delay allocated before entering sectors and various forms such as speed, height layer and course adjustment of aircrafts in multiple sectors, and can be used for effectively supporting flow management and air trafficcontrol coordinated operation decision to solve the actual operation problem of air traffic control in multiple sectors.

Description

technical field [0001] The invention belongs to the field of aviation technology, and in particular relates to a method for constructing a multi-sector conflict detection and release model and a model constructed by the method. Background technique [0002] With the increase of air traffic flow in the future, the limited airspace and busy routes are facing increasing flow pressure, and the air traffic operation mode will also change from the operation mode based on separated airspace and scheduled routes to the operation based on trajectory In the trajectory-based operation mode, the flow management will be more closely integrated with the control operation. The flow management strategy includes the ground waiting strategy before takeoff and the metering management strategy implemented at the waypoint in the air, etc. The waypoint metering management strategy includes the time-based metering management The measurement management strategy based on time interval (Minutes-in-tr...
