Modeling is the process of producing a model; a simulation of a system is the operation of a model of the system.

The model can be reconfigured and experimented with, although usually this is impossible, too expensive or impractical to do in the system it represents. The operation of the model can be studied, and hence, properties concerning the behavior of the actual system or its subsystem can be inferred.

In its broadest sense, simulation is a tool to evaluate the performance of a system, existing or proposed, under different configurations of interest and over long periods of real time.

Simulation is used before an existing system is altered or a new system built, to reduce the chances of failure to meet specifications, to eliminate unforeseen bottlenecks, to prevent under or over-utilization of resources, and to optimize system performance.

Modeling and simulation are common tools in the engineering field and their use often results in multivariate systems (MIMO – Multiple Input Multiple Output).

These systems are usually described by implicit nonlinear equations. In general, the simulation software available does not evaluate the uncertainties associated with the variables and rarely discloses the equipment models used, which with some effort allow the calculation of these uncertainties.

In recent years, Computer modeling and simulation has been gaining popularity in both government and industry. Computer simulation modeling can assist in the design, creation and evaluation of complex systems. 

Designers, program managers, analysts and engineers use computer simulation modeling to understand and evaluate “what if” case scenarios. It can model a real or proposed system using computer software and is useful when changes to the actual system are difficult to implement, involve high costs or are impractical.

Some examples of computer simulation modeling familiar to most of us include:  weather forecasting, flight simulators used for training pilots, and car crash modeling
