How It Works
Utilization = Arrival Rate ÷ (Cashiers × Service Rate)
• Utilization < 0.8: System runs smoothly
• Utilization 0.8-1.0: System under stress
• Utilization > 1.0: System overloaded - queues grow infinitely!
Legend: Green boxes = busy cashiers, Gray boxes = free cashiers, Blue circles = waiting customers
