On Application of Queuing Models to Customers Management

A Single Server, Variable Service Time is known as an M/D/1 system. FALSE An M/D/1 system would be a single server, constant service time system. The most commonly used queuing models assume that the arrival rate can be described by a Poisson distribution.

Waiting-Line Models - Pearson Education

The single-server model with Poisson arrivals and constant service times is a queuing variation that is of particular interest in operations management, since the most frequent occurrence of constant service times is with automated equipment and machinery. This type of queuing model has direct application for many manufacturing operations.
