Systems simulation is a set of techniques for using computer

Computer

A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem...

Simulation

Simulation is the imitation of some real thing available, state of affairs, or process. The act of simulating something generally entails representing certain key characteristics or behaviours of a selected physical or abstract system....

, the operations of various kinds of real-world facilities or processes (Law 2007). The computer is used to generate a numerical model of reality for the purposes of describing complex interaction among components of a system. The complexity of the system surges from the stochastic

Stochastic

Stochastic refers to systems whose behaviour is intrinsically non-deterministic. A stochastic process is one whose behavior is non-deterministic, in that a system's subsequent state is determined both by the process's predictable actions and by a random element. However, according to M. Kac and E...

(probabilistic) nature of the events, from the rules for the interactions of the elements, and the difficulty to perceive the behavior of the systems as a whole with the passing of time.

There are many software packages are available to do this job.
