Explain
Scripts enhance Arena models with custom logic not possible through standard module configurations.
They provide control over entity behavior, event timing, resource logic, and system-wide orchestration.
SIMAN blocks define low-level process logic inside Assign, Decide, Hold, and custom blocks.
VBA scripts automate experiments, data import/export, and reporting.
Widely used in manufacturing, logistics, healthcare, defense, call centers, and supply chain simulations.
