Lesson notes
Key points
- An analytical model like an M/M/1 queue gives exact answers fast, but only if its assumptions, such as random arrivals and one server, really hold.
- Picture trucks queuing at a shovel at a Tarkwa pit: breakdowns and shift changes break the formula's assumptions, so simulation earns its cost.
Takeaway: Use formulas when assumptions hold; simulate when reality is messy.
Quick check: Would you rather solve a queue with a formula or by simulation?
- Exact formula
- Simulation
- Depends on the case
If the model's assumptions fit the real system, use the formula; if not, simulate.
