| With the increasing scale and volume of business of domestic airports,there are many problems in most airports,such as low level of information automation and insufficient collaborative decision-making ability,which directly affect the efficiency of airport flight ground support process and lead to the reduction of normal flight release.The flight ground support process in an airport involves multiple support links and is affected by many internal and external factors,so the support mode is relatively complex.Moreover,the traditional analysis methods used by airports are inefficient and lack of deep data mining and modeling processing,so it is difficult to find out the deep restriction relationship of flight ground support.Through analyzing and mining the flight ground support data of the airport,the deep-level mode of flight ground support can be found,so as to control the operational links of flight support,and to better monitor the key support links and give early warning of delays,so as to improve the security efficiency of the airport[1].In order to improve the efficiency of airport flight ground support,shorten the support time and strive for the normal release of flights,the whole support process can be compressed by effectively controlling the operation time of key support links.In this paper,the flight support process and the support process and operation time of each operation link in the airport were first understood through field research.Based on this,the flight ground support flow chart was constructed and the characteristics of the ground support were analyzed.Secondly,AOE-net is constructed for the job nodes in the process to obtain the critical path.Combined with the delayed jobs in the support data,the delayed jobs on the critical path are screened,which is called"critical delayed jobs".Then,the association rules mining algorithm was used to analyze the"critical delayed operations",and the internal correlation among delayed operations was obtained,and the direct factors affecting the delay of airport flight ground support operations were deeply explored.Then,according to the strong association rules obtained,the early warning model is set for the guarantee link,and the delayed operation is controlled in the guarantee process.Finally,an example of Mianyang Airport is simulated and verified to obtain the efficiency improvement rate of flight support at the airport,which verifies the effectiveness of the early warning model in the flight support process. |
