Operational simulation tools are used to gain a better understanding of complex systems. These tools can range from looped hardware simulations to high-fidelity radar simulations. In this article, we'll explore the different types of operational simulation tools and how they can be used to evaluate systems. Looped hardware simulations are used to test parts of a system. This type of simulation is useful for predicting the trajectory and damage caused by a rapidly moving piece of metal that impacts various points on a tank.
Statistical models can also be used in conjunction with simulation models to aid operational evaluation. The Longbow Apache was tested using modeling and simulation. Leidos offers RADSIM, a high-fidelity radar simulation system for flight systems, flight simulators, unmanned aerial vehicle simulators and other purposes. Development tests can provide substantial information about the failure modes of individual components, including the entire prototype. STAR-CCM+ is a multiphysical computational fluid dynamics (CFD) tool that can be used to study how products work under real world conditions. The Navy's Operational Testing and Evaluation Force generally uses the Naval Analysis Center to perform much of the validation of its models. Field usage data can be included in a file to provide great opportunities for the validation of the methods used in the design of operational tests.
The identification of outliers in the patterns that show the vast majority of the inputs of a constructive simulation can be used to better understand the regions of the input and output space where the behavior of the simulation changes qualitatively. The main problem with simulations is that they lack fidelity, which means that units cannot use the terrain to hide their movements or emulate having entrenched defensive positions. It is also an inefficient method for understanding the response surface of the simulation model. Given the importance of model validation when deciding the usefulness of a simulation for use in operational tests, it is important to consider all aspects of comprehensive validation when creating guidelines relating to verification, validation and accreditation. In conclusion, operational simulation tools are essential for gaining an understanding of complex systems. They range from looped hardware simulations to high-fidelity radar simulations and can be used to evaluate systems in various ways. Additionally, field usage data can be included in a file to provide great opportunities for validating methods used in operational tests.
However, it is important to consider all aspects of comprehensive validation when creating guidelines relating to verification, validation and accreditation.
