Imagine you are the marketing manager for a firm that is planning to introduce a new product. Monte-Carlo simulation enables you to quantify risk, whereas stochastic optimization enables you to minimize risk. In each model, there will be several input variables. Monte Carlo simulation performs risk analysis by building models of possible results by substituting a range of values—a probability distribution—for any factor that has inherent uncertainty. For example, the following Monte Carlo method calculates the value of π: 1. Monte Carlo simulation, the computer varies each input within a predetermined range hundreds of times and generates a range of outputs along with the frequency of these outputs’ occurrence. Monte Carlo Simulation [ezcol_1half] … an Add-in for Excel. Deterministic optimization is a more commonly used tool but has the same drawback as the single number estimate method described above in the introduction to Monte Carlo simulation; it does not take uncertainty into account.
