Best for Python developers and researchers who want a scriptable, embeddable discrete-event simulator rather than a GUI-based tool. Operations and supply chain teams modeling queuing, congestion or system behavior over time rather than solving a single optimal allocation. Manufacturing, logistics and healthcare teams who want to test process designs before building them physically. Manufacturing and warehouse operations teams evaluating process or layout changes before capital investment.
