A computer simulation language describes the operation of a simulation on a computer. There are two major types of simulation: continuous and discrete event though more modern languages can handle more complex combinations most languages also have a graphical interface and at least a simple statistic gathering capability for the analysis of the results. An important part of discrete-event languages is the ability to generate pseudo-random numbers and variants from different probability distributions. Examples are:
- Discrete event simulation languages, viewing the model as a sequence of random events each causing a change in state.
- ExtendSim - Simulation software for discrete event, continuous, discrete rate and agent-based simulation**GPSS
- Simio software for discrete event, continuous, and agent-based simulation.
- SimPy, an open-source package based on Python
- SIMSCRIPT II.5, a well established commercial compiler
- jEQN a Domain Specific Language for M&S of Queueing Networks
- Continuous simulation languages, viewing the model essentially as a set of differential equations.
- Hybrid, and other.
