Simulation Modeling Examples

Simple Simulation Example

A programming tool that provides a programming approach can be evaluated by how easy it is for a user with no experience to make the first step.

In traditional programming languages, the simplest example is printing "Hello, world!" to the screen.

In discrete-event simulation, however, such an example should be represented by a model. Therefore, the simplest suitable model is selected.

A single-server loss system is a suitable model. This is a classic example of the simplest system in queuing theory.

In this system, entities arrive at a single server according to a Poisson process, and service time is exponentially distributed.

Note that this is a special (edge) case, since the total system capacity is 1 — there is no queue in this system. According to Kendall's notation, it is an M/M/1/1 queuing system.

Here is a block simulation model of an M/M/1/1 queue.

Alternatively: a Simula-like simulation model of the same system.
