Simulation is defined as the process of creating a representation of an existing system which can be tested to identify and understand underlying factors that cause that system to change its behavior. Simulation is used in many industries, including medical, transportation, aeronautics, military, and even retail and culinary. All systems that have a quantifiable feature can be simulated or recreated by the same people designing the systems.

The purpose of a simulation is to allow system designers to understand what they are creating and how these systems will respond to certain environmental factors. For example, an ins simulation will allow a system analyst to monitor the behavior and possible model errors of the INS relative to the situation or scenario where it is being tested. Because of this, engineers and programmers can correctly calibrate a navigation system that is dependent on GPS/INS, which is used heavily in navigational systems for aircraft and autonomous driving in automobiles.

Building Alternative Designs

The same system designer or analyst who tries to understand the merits of a system through a simulator can design alternative designs without physically manufacturing the system. The simulation software can calculate the construction of the system, allowing any analyst and engineer to throw the system into different real-world scenarios.

The simulation phase saves any company the cost of constructing physical systems for testing and calibration. Can you imagine how costly it would be to fabricate the designs of a system? To make decisions such as the proper placement of wires and components and installing it with programs it may not necessarily respond to positively? The use of a simulation program provides the designer and the engineer practical feedback on the efficiency of the systems. It’s like looking into the future and determining where a system might go wrong and correcting any potentialities of a system breakdown.

Finding Early Solutions

Simulators allow engineers and programmers to find early solutions to problems that might persist in the system in the future. The program permits the study of a problem at different levels so that solutions can be tested before they can actually be implemented. Most designers prefer finding solutions at the top level so that the components below can be re-adjusted depending on the results of the tests.

This top-down strategy works for most systems. It saves a considerable amount of time since changes made from the bottom will affect the overall functions of the system, requiring system designers to recalibrate and adjust each component at different levels of the system.

Demonstrating To Students

If a system is being used to teach students, whether in the secondary or collegiate level, a simulation program is a good alternative than actually letting students handle a physical system. Simulation programs, in particular, use animations and computer graphics to show engineering students how a system’s components will react to different environments. This is a better and more meaningful understanding of how a system works and how it must be re-engineered, reprogrammed, and redesigned.

Testing systems through simulation ensure the best possible end product. It eliminates the need for costly testing centers and allows designers to react almost simultaneously to the results of the simulation.
