Monte Carlo Simulation

Definition

Monte Carlo Simulation is a statistical technique that utilizes random sampling and repeated simulations to model and analyze complex systems or processes. By generating a range of possible outcomes based on variable inputs, this method helps assess risks and uncertainties in decision-making, making it essential in evaluating financial performance and optimizing supply chain operations.
