Summary
Simulation modeling is increasingly important because the current operational complexity and dynamism overwhelm staff. Models are helpful for predicting future behavior, finding optimum solutions, and exploring alternatives. Models offer speed and agility compared with setting up physical test beds.
Test beds are also useful as a reality check for the model; the fit of actual behavior to the model results improves the confidence in the model and points to areas where tuning or adjustments are needed.
Capacity planning prevents future disruption caused by insufficient resources.
