An Introduction to the Use of Modeling and Simulation Throughout the Systems Engineering Process

Keywords function modeling simulation processes systems engineering process
Standards groups

Resolution: The degree of detail and precision used in the representation of real world aspects in a model or simulation
– Models and simulations at lower levels of M&S “pyramid” tend to exhibit more resolution; this does not necessarily imply more accuracy
Aggregation: The ability to group entities while preserving the effects of entity behavior and interaction while grouped
– “Campaign-level” simulations often aggregate military entities into larger groups (e.g., brigades vs. battalions)
Fidelity: The accuracy of the representation when compared to the real world
– Greater fidelity does not imply greater resolution
