Lesson notes
Key points
- A random number between 00 and 99 is drawn, and its range on the cumulative table decides when you arrive at the shovel.
- The shovel is busy, so you join the queue, and the simulation clock records every minute you sit waiting.
- Another random number sets your loading time, so no two runs ever give you exactly the same day.
- After hundreds of trucks like you, engineers average the results to decide whether a second shovel pays off.
Definitions
- Monte Carlo simulation
- Repeating a model with random inputs many times to estimate average system performance.
Takeaway: Simulation uses random numbers and many runs to estimate averages.
Quick check: In Monte Carlo simulation, what converts a random number into an arrival time?
- The average arrival time
- Ranges on a cumulative table
- The shovel's loading rate
Each event gets a random-number range matching its cumulative probability.
