Knowledge quiz

Check your understanding before marking the unit complete.

1. 240 parts arrive at heat treat in 90 minutes while effective service rate is 75/hour. What happens?

2. CMM measured Wq=3.2h, λ=87.5/hr. Little's Law estimates Lq about:

3. FlowForge pooled CMM machines; average wait fell but aerospace tail wait rose. Best response:

4. PPAP review slots use 10% overbooking with 8% no-show history. Risk if demand spikes 21% above nominal capacity?

5. Portal A/B: same Wq=3.2h but enriched status cut escalations 28%. This shows:

6. Average λ=72/hr at heat treat with μ=75/hr sounds healthy, but peaks hit 90/hr. Key lesson:

7. Kingman-style intuition: as ρ approaches 1, wait time:

8. Measuring queue at shipping instead of the constraint led a fictional plant to fail fixes. FlowForge should measure queues at:
