Study On Capacity Evaluation Of Parallel Runways In Isolated Operation

The simulation study of airport capacity assessment is a means to effectively improve the airport operation efficiency and throughput,which can reduce the airport construction cost,accurately quantify the runway service level and provide reference for the control operation program.At present,the airport mainly uses the general simulation evaluation software and the query airport runway capacity calculation manual methods to obtain the airport runway capacity.But most general simulation software using curing parameters input and take the airport runway time distribution of airport runway capacity simulation research,the aircraft in the isolated operation mode of parallel runway to take off and land operation process to consider not comprehensive,and foreign capacity evaluation simulation software to run the program does not accord with domestic the truth,not suitable for domestic airport runway capacity assessment.Therefore,starting from the relevant factors affecting airport capacity,this paper uses Any Logic simulation tool to realize the runway capacity assessment model,and analyzes the variation trend of airport capacity under the influence of various factors when the airport is operating in isolation mode through the simulation results.The main work of this paper is as follows:(1)A variety of relevant factors affecting airport capacity are selected,such as wake interval,escape path configuration,runway crossing,runway attributes and natural conditions.The capacity assessment model of FAGS＿CS(Final Approach Stage and Ground Stage Co-simulation)based on the isolation operation mode is established,and the accuracy of the takeoff and landing distance of incoming and departing aircraft calculated by the model is verified,which lays a foundation for analyzing the influence of various related factors on the airport capacity when the isolation operation is implemented.(2)Using Any Logic simulation tool,the runway capacity evaluation model of MULTI＿AGENT is implemented to analyze the influence of relevant factors on the airport capacity when the airport is operating in isolation.Through simulation analysis,it is found that the airport capacity is not only related to the nature of takeoff and landing runway itself,but also restricted by wake interval,escape path configuration,runway crossing and natural conditions.When one of the related factors changes,the airport capacity will be affected to different degrees.For example,the higher the atmospheric temperature is in a certain range,the lower the airport capacity will be,and the higher the runway elevation will be,the smaller the airport capacity will be.The simulation analysis can not only find out the influence degree of the relevant factors on the airport capacity,but also put forward reasonable suggestions for the airport planning and construction according to the data obtained from the simulation,which proves that the simulation model is practical and can be used as a tool for the capacity evaluation of the airport when the isolation operation mode is implemented.
