Optimal Wheelchair Passenger Service in the Airport

摘要

This paper uses a queuing model of multi-server system to offer optimal airport wheelchair service which minimizes the cost and offers service of high quality. It addresses the performance of airport wheelchair service associated with the waiting time of passengers who need the service. According to the related data, we can know the cost of wheelchair service in unit time C_s and the loss of keeping passengers waiting for service in unit time C_w. Basing on the related equations of queuing theory, we calculate the ratio between C_s and C_w and compare it with numerical interval in different number of the wheelchairs, thus we get the optimal number of wheelchair and the cost. We take the O'Hare International Airport as an example and calculate the optimal wheelchair passenger service. This model can be applied to airports of different shapes and sizes.
