QUEUING MODELLING OF AIR TRANSPORT PASSENGERS OF NNAMDI AZIKIWE INTERNATIONAL AIRPORT ABUJA, NIGERIA USING MULTI SERVER APPROACH

Abstract

The Multi Server approach of modeling was adopted in this study to develop a mathematical model to solve problem of queuing of air transport passengers at the Nnamdi Azikiwe International Airport (NAIA), Abuja, Nigeria's capital city. The airport just like similar facilities in the aviation industry of the country faces problems of many passengers queuing for boarding, departure with different arrival rate due to non-availability of state of the art logistics management mechanisms for predicting the nature and service demands of travelers. A mathematical queuing model was developed in this study and simulated using data obtained from four different air transport companies that consisted of two domestic carriers (Arik Airline, Aero Contractor Limited) and two international carriers (British Airways and Ethiopian Airline). Result showed that there was shortage in total number of aircrafts available to effectively serve the monthly average of 21,863 domestic and international passengers at the airport. The system required modeling service factor of 0.5 (utilization factor of 0.4, 0.6 and 0.9) at 5% significance level. The simulation showed that in order to meet daily need of passengers at NAIA Abuja based on carriage capacity of available aircrafts; each international airline required one additional aircraft. Each domestic airline required five additional planes in her daily feet.
