Study On Optimization Of Air Route Capacity Model Based On Unascertained Number

With the development of the domestic aviation industry,the increasingly crowded airspace and the surge in flight volume have been difficult to reconcile,and the current operating rules of the route are also difficult to meet the demand for rapid growth of flight volume.Optimization has become the primary method for increasing airway capacity.At the same time,in order to increase the airway capacity more scientifically and effectively,a reasonable and accurate assessment of the capacity of the airway network is required.This paper starts with the capacity model of the flight segment and the capacity at the intersection of the flight path,and divides the flight segment into three types: mixed flight path,single circulation flight path,and parallel flight path.Based on previous studies,the capacity model of these three flight segments was carried out.Evaluation and comparative analysis of three types of flight segments.At the same time,the unascertained number theory is introduced.By calculating the unascertained numbers in the segment deterministic capacity model,a segment capacity model based on unascertained numbers is obtained.Routes are classified based on the statistics of route traffic.Based on this classification,the crossing airspace is divided into three categories: trunk and trunk crossing airspace,trunk and branch crossing airspace,and branch and branch crossing airspace.Based on this,the three types of routes are calculated.The capacity model of the cross-airspace and based on the uncertainty of some factors in the model,an airway capacity model of the cross-airspace based on unascertained numbers was obtained.The maximum flow algorithm is used to find the bottleneck area in the airway network that limits the growth of airway capacity.Based on this,the airspace configuration and operation mode are optimized.The idea of cross airspace prohibition is proposed.Through qualitative analysis,the optimized cross airspace prohibition is optimized.The line can effectively increase the capacity of the airway network.Finally,the cross-airspace capacity values before and after optimization and the area they occupy are compared.The research in this paper can more scientifically and reasonably understand the capacity of the airway network.Based on the measurement subjective factors in the capacity model,some factors cannot be accurately taken.Therefore,the existing deterministic capacity model of the airway network is extended to the uncertain capacity model;The optimization method of the airway crossing airspace can effectively increase the capacity of the airway network,which has certain reference significance for future research on the capacity optimization of the airway network.
