| In recent years,China is the top country of the world with the fastest growing speed of civil aviation construction,but still cannot meet the requirements of civil aviation transport caused by rapid economic development.At present,the research for hub airport construction and planning in China is mainly concentrated in the perspective of architectural design research and traffic planning perspective,from the perspective of Operations Research,from the use of resources and planning perspective research is still relatively scarcity.Therefore,from the point of view of management,it is of theoretical and practical significance to organize and manage the passenger service resources of the aviation hub.An aviation hub covers variety modes of transportation,just by taken advantage of various modes of transport by spatial combination,organic convergence,and coordination,to make the transportation resources obtain the reasonable and effective use of uniform distribution in time and space.The check-in Hall,Departure Lane and Arrival Lane are three important nodes of the airport hub in land side,the service efficiency and the intensive utilization level are important indicators to measure the quality of the project.At present,the two major drawbacks still exist in the airport construction and management in China: one is the way of management mainly depends on the experience based on "qualitative" management,the other is extended to rely solely on hardware to meet the growing demand for land service.It is not only expensive,but also relatively inefficient to use the traditional management methods to solve the problem of the increase of the demand for the land service of the aviation hub.In this paper,based on the queuing theory,established the check-in hall queuing model,departure and arrival curbside service queuing model,and based on the model simulation experiments,provide quantitative decision support information for the service capacity planning of aviation hubs in land side.First of all,the paper points out the defects which may exist in the study of classical queuing theory on M/M/1 and M/M/c two queuing way.Based on the classical queuing theory,three parallel M/M/1 queuing systems are simplified as one independent M/M/1 queuing system,which arrival rate is reduced to 1/3.In simplified system,the customer's arrival rate obey Erlang distribution which does not meet with Markov propertity,so,Little formula can not play a role.Analytic method is used by classical queuing theory.It is difficult to reflect the influence of random factors on the performance of the system,based on AnyLogic simulation model and simulation model based on GPSS/Java has made the following three conclusions:No.1 In two kinds of queuing system,server utilization efficiency is almost the same,the customer average waiting time has little difference,which is contrary to theclassical queuing theory.No.2 M/M/c queuing system can effectively reduce the number of customers waiting for a long time,but also reduce the number of "zero wait" customers,so that customers can queue waiting time is more uniform.No.3 During the low peak period,the queue length of M/M/c system is significantly shorter than the parallel M/M/1 system.At the peak period,the fromer is significantly longer than the latter.M/M/1 queuing system can change the exponential distribution passenger flow to Erlangian distribution,so it can effectively resist the short-term impact of large passenger.It is the classical conclusion of queuing theory that M/M/c queuing system can effectively improve the service efficiency and reduce the average waiting time,which is the theoretical basis for managers to choose the way of queuing.The conclusion of this paper breaks the theory of M/M/c queuing method could effectively improve the service efficiency,so that managers can more clearly recognize the two queue at the service desk utilization,average queue length,maximum queue length,average waiting time and other indicators of the real data and their advantages and disadvantages.Based on the findings,a suggestion for check-in queuing mode of Beijing New Airport is the combination of M/M/1 and M/M/c.Secondly,the paper studies the traffic capacity of the departure lane of the aviation hub.First of all,the vehicles in departure Lane are divided into three kinds,the trying to park vehicles,the parking vehicles and the trying to leave vehicles,and was analyzed and calculated by AnyLogic simulation model based on double lane driveway and three lane driveway,the conclusion is that the number of trying to park vehicles and trying to leave vehicles accounted for almost 90%,so the travel lane resource is a decisive factor affecting curbside capacity,the economy of the two lanes and four lanes was less than three lanes model.Then,the simulation model based on Vissim proved that under the same service level,the three-lane model is about twice as much as the capacity of the two-lane model.Finally,based on the weaving area highway capacity calculation method by “Highway Capacity Manual”,traffic capacity of the dual parking way and dual carriage way is calculated.The result by simulation model based on AnyLogic is more consistent with the result by traffic flow,and the capacity of the three Lanes model is 1800pcu/h.The Beijing New Airport has doubled departure layers,the fouth layer has three departure lanes which formed by three lanes,the third layer provide two departure lane which formed by three lanes.It could meet the requirements of 120 million passengers per year.Finally,based on the GPSS/Java simulation software,the capacity of the departure taxi system is studied.The modeling logic of the single lane taxi departure system is analyzed in detail;the business logic of the vehicle controller is realized by GPSS/Java language;to achieve the business logic of vehicles out of berth,the berth is defined assingle service entity;through analysis method based on Monte Carlo algorithm,the random distribution of passenger boarding time the curve is realized,and then several rounds of simulation experiments was conducted for single lane taxi boarding system.The change of traffic capacity is obtained under different berths.It also points out main factors influencing the capacity of the single lane taxi system is the mutual coupling and interference in vehicle access and exit process.Then the modeling research on three lane taxi boarding system was established,and then it was compared with the single lane boarding system capacity,in the view of quantitative data.Finally,the indented form taxi boarding system was modeled and analyzed,and the simulation model of the capital airport T3 departure taxi system(owning 32 berths)was established,and the value of the traffic capacity is 983.3 vehicles per hour.Then the model of Beijing New Airport departure taxi system(owning 60 berths)was established,the capacity is 1141.65 vehicles per hour.The coming conclusion is,increasing the number of berths can't increase the capacity accordingly.When we modified the simulation model by reducing the number of berth to 40,the capacity is 1001 vehicles per hour,which could reduce the difficulty of field management.From the view of research content,terminal landside passenger service system is a typical dynamic,discrete,stochastic system,so it is difficult to be solved by analytical method,system simulation method has the characteristics for specific problems,is problem oriented and very difficult to upgrade the academic value of paper.This paper research on queuing method in theory breaks through the classical queuing theory queuing contrast in conclusion "single queue" and "multi queue" in the guiding ideology,it can make the management more clearly understand their respective advantages and disadvantages of the two kinds of queuing system;research on the Departure Lane and Boarding Taxi system,although has the characteristics of problem oriented,but the case analysis is one of the commonly used method of large aviation hub in planning and design for the rationality of the design scheme,the capacity of the facility,and the simulation model can be created from more angles to the management personnel to provide quantitative information for decision support.From the perspective of research methods,modeling analysis on aviation hubs landside check-in hall,departure lane and boarding taxi system is completed by system simulation method,and the landside passenger service resource planning of the Beijing new airport is studied as a case to find out some useful conclusion for the resource planning of airport passenger service resource,and to provide a practical reference and theoretical thinking on the airport passenger service resources of land side. |
