Chapter 7 Queuing Theory

In the previous chapter we have learned to implement complex discrete-event simulations using the Simmer package. Basically all simulation models we implemented involved some queue of customers requiring a service. There is a whole area of probability called, queuing theory, which studies the mathematical foundations and properties of such models. In this chapter we will define a bit more formally what queues are and how they work. We will also learn that we can actually already know a lot about the behavior of the queue by knowing a few key parameters.
