Basic Queuing Process
Customers requiring service are generated over time by an input source. The required service is then performed for the customers by the service mechanism, after which the customer leaves the queuing system. We can have following two types of models: One model will be as Single-queue Multiple-Servers model (fig.1) and the second one is Multiple-Queues, Multiple-Servers model (fig.2) (Sheu, C., Babbar S. (Jun 1996)).
