Queuing models


Every time demand exceeds capacity a queue is formed, which means that
customers have to wait for service.

Queuing models are designed to help determine an appropriate level of service.
These models consider:

1. The speed of the service, and
2. The optimal number of service stations

The goal is to minimize the cost of providing the service.
