Empirical Analysis of Priority on a FCFS Queue Discipline In Nigerian Banking System

Abstract

Queues are virtually unavoidable phenomenon in Nigerian banking system. While banks stride to meet customers services’ satisfaction, customers who  do not go immediately into service must wait in line (if any). The queuing discipline in banks has been first-come-first-served (FCFS). What happen to the waiting time distribution when priority is encapsulated into a FCFS discipline is the interest of this paper. Data from a typical leading bank in Nigeria are analyzed using chi-squared technique on the assumption of Poisson arrival and exponential service times. The need for improved service control measures on banks’ peak periods is emphasized.
