Monte Carlo Simulation

Definition

Monte Carlo simulation is a statistical technique used to model the probability of different outcomes in a process that cannot easily be predicted due to the intervention of random variables. This method relies on repeated random sampling to compute results, allowing for the analysis of complex systems and uncertainty in various fields, including finance, supply chain management, and risk assessment.
