Paper Title
Application of Queuing Theory For The Improvement of Bank Service

Abstract
Lines of waiting customers are always very long in most of the banks. In this paper, the M/M/Z/∞:FCFS model is converted into M/M/1/∞:FCFS to know which one is more efficient, a line or more lines. To do this, first we establish the optimization model of queuing and calculate the optimal model of queuing. Second, calculate the optimal number of service stations to improve operational efficiency. Third, we calculate the optimal service rate and the service efficiency by the operating costs. Based on these aspects, the result of analysis was effective and practical.
