Comparing Queue-Server Combinations


This example shows a comparison of a single-queue, multiple-server system with a multiple-queue, multiple-server system.


In this model, both systems share the same average service time and achieve the same throughput. However, the single-queue system exhibits shorter delays than the multiple-queue system.

The comparison of these two systems is the classic "queuing for multiple bank tellers" problem and shows that forming a single line for multiple tellers reduces the average delay, compared to forming one line for each teller.
