| Performance Metric | Value | 95% Confidence Interval | |-------------------|-------|--------------------------| | Average queue length (customers) | 2.8 | ±0.4 | | Maximum queue length | 9 | - | | Average waiting time in queue (min) | 12.5 | ±1.2 | | Average total time in system (min) | 18.2 | ±1.5 | | Server utilization (%) | 88% | ±3% | Utilization is high (88%), leading to growing queues during peak hours. The average wait time (12.5 min) exceeds the desired target of <5 minutes. 5. What-If Scenario (Proposed Improvement) Scenario: Add a second identical server (multi-channel queue).
One queue feeding two identical service desks. anylogic example
