Monte Carlo Simulations

Definition

Monte Carlo simulations are mathematical techniques that use random sampling to estimate the probabilities of different outcomes in processes that are uncertain. This method is particularly useful for assessing risk and uncertainty in project management, allowing decision-makers to visualize potential variations in project outcomes based on different input variables. By simulating a range of scenarios, Monte Carlo simulations provide valuable insights that help in project selection and cost control, making them essential tools for effective project planning and execution.
