Last updated
Evaluates queueing-system reasoning for single-line versus multiple-line bank teller designs. Strong answers compare M/M/c pooling with parallel M/M/1 queues, waiting-time averages, variance, stability, fairness, and operations.
Scenario: A bank wants to choose between a single‑line multi‑server queue and multiple independent queues.
Question 1: Compare expected waiting time and variance between a single‑line multi‑server system and multiple independent queues.
Question 2: Under what customer‑load scenarios does one system outperform the other?
Question 3: How would you model customer experience and throughput analytically?
Question 4: What data would you collect post‑implementation to validate the design choice?
