Micro-simulation Research In Operation Of Single Runway

The micro-simulation of runway is an effective means to plan runway.It plays an important role in saving resources,accurately working out the runway operation capacity of the airport and providing constructive referenced opinions for management and design departments.At present,runway capacity is obtained by the general evaluation tools and find the airport capacity manual,but using parameter input and runway occupancy time distribution etc to implement runway operation simulation,and the rules built in the foreign simulation tools is not conform to the actual operation of the domestic aircraft,is not suitable for planning the runway,is not consider carefully for the operation process of the aircraft.The results obtained from the airport capacity manual are not accurate compared with the actual results.In order to plan the runway in the best way,it is necessary to understand the micro-parameters that affect the efficiency of runway.This paper with a variety of micro-parameters,build model by Anylogic simulation tool,analyzed the effect of micro-simulation on runway operation efficiency.The paper main works as follows:(1)Extract a variety of micro-parameters that affect runway operation efficiency.The dynamics model and kinematics model of the aircraft taking off and landing are analyzed,and the accuracy of the moving distance of the aircraft by the model is verified.This model lays the foundation for analyzing the effect of micro-parameters on runway operation efficiency.(2)Abstract the simulation model research object and the state of the randomly generated departure and arrival aircrafts during the operation process.Combinating with the actual operation of the airport,the paper designs rules of aircrafts choosing take-off holding points and the order of arrival and departure aircrafts etc.(3)On the Anylogic simulation platform,the influence of micro-parameters on runway operation efficiency is analyzed in detail according to different operating rules and different micro-simulation conditions.Through the simulation analysis,it is shown that the factors influencing the runway efficiency are not only related to the nature of the runway,but also affected by natural conditions,aircraft performance,entrance and exit layout of runway,operating intervals,and operating modes etc.When there are unique parameters variation in many micro-parameters,runway operation efficiency is affected by different degrees.Through simulation analysis,not only find out the reasons that affect the runway operation efficiency,but also make up for the lack of analysis of the impact relationship between micro-parameters and operation efficiency in airport planning.It is proved that the simulation tool is scientific,reasonable and reliable,and can be used as a tool for airport planning and design.
