Simulation modeling examples

Simple simulation example

The product which offers some programming approach can be evaluated by how easy user with no experience of this product can make the first step.

A traditional example of the easiest code for conventional programming languages is the output of "Hello, world!" to the screen. However, such example for discrete-event simulation should be represented by a model. So, the simplest appropriate model should be chosen.

A model of a single server loss system is such a suitable case. This is the simplest classical queuing theory system. It should be noted that this is a degenerate case, since there is no queue as such in this system.

So, the entities flow in this system arrives as a Poisson process with exponentially distributed interarrival time. The service time value is exponentially distributed too. According to Kendall's notation this is a M/M/1 loss system.

A block simulation model of M/M/1 loss system is considered here.

And here a Simula-like simulation model of the same system is considered.
