Abstract
In this work, an understanding is sought of Queuing characteristics at an NNPC Mega
station in Nigeria when petrol is easily available so as to compare with the queuing
characteristics when there is petrol scarcity which is a recurring decimal in the country.
The Mega station with queuing discipline of First-In First-Out, a service mechanism of
single-queue multiple-channels and a system capacity of an infinite source has distinct
operating characteristic of traffic intensity being 0.77. Further analysis of the queuing
characteristics revealed that, the average number of vehicles in queue is from 2 to 3 while
the average time a vehicle spends in queue is 1.58 minutes. The probability of vehicle
queuing on arrival is 0.5993 while there is a 0.4007 probability that a vehicle may not
queue on arrival. It was concluded that with 1.8 minutes, a vehicle spends more time in
service than on the queue and since the number of vehicles on the queue is < the number
of active servers, there is no queue at NNPC Mega station Minna when there is no fuel
scarcity country.
