The Discretization Method To Improve The Time And Space Efficiency Of Complex Airspace Operation

With the increase of airspace flow,airspace operation becomes complicated.Analyzing its operation characteristics and improving the index efficiency of airspace operation efficiency are of great significance to ensure the efficient operation of airspace.In this thesis,the discretization method is used to divide the airspace into different levels,quantify and evaluate the efficiency of spatio-temporal efficiency index of complex airspace operation,and provide a new method to solve the problem of low efficiency of airspace operation.Firstly,the evaluation index system of airspace operation is established,and the evaluation index of spatio-temporal efficiency is selected for research through weight calculation.In this thesis,the discrete unit of airspace is constructed by discretization and the digital model of airspace is established,so as to make greater use of limited airspace,and then expand and establish the spatio-temporal dynamic and efficient management architecture of space and space integration.In this thesis,the space cell is coded and located,and the occupied space is accurately represented by unit coding technology.Secondly,the index considering air traffic safety,time efficiency and space utilization rate is constructed,and an evaluation model considering the optimal spatial and temporal efficiency resources of airspace is established.Then,the discretization algorithm is used to divide the complex airspace by layers,and the operation data of the routes at low altitudes and the information of the obstacle restricted area are obtained in combination with the actual situation.The spatio-temporal efficiency of the airspace operation is improved,and the value of spatio-temporal efficiency is verified by calculating the optimized speed and height.Finally,the extension analytic hierarchy process(AHP)was applied to evaluate the operational efficiency of the airspace,and the improvement of the overall operational efficiency of the airspace by the index of spatio-temporal efficiency was emphasized.The results showed that after the spatio-temporal efficiency was improved by the discretization method,the threshold of the operational efficiency of the airspace was 0.02168,and the result was good,which was 0.03173 of the operational efficiency of the original airspace.Improving the spatiotemporal efficiency index threshold of airspace operation will greatly improve and change the overall efficiency of airspace operation.
