Simulation

What is it

Simulation models a real system using random sampling to imitate its behaviour over time, often via Monte Carlo methods, used when a system is too complex for an exact mathematical solution.

Why it matters

Simulation is used throughout finance, engineering, and operations wherever a system involves too much randomness or complexity for an exact formula — from pricing financial derivatives to testing how a new factory layout performs under variable demand.

Exam tip

Always run enough simulation trials to get a stable, reliable estimate before drawing conclusions — a simulation with too few runs can give a misleadingly confident-looking answer that's actually just random noise.
