7 Monte Carlo simulation (also known as the Monte Carlo Method) lets you see all the possible outcomes of your decisions and assess the impact of risk, allowing for better decision making under uncertainty. Monte Carlo simulation is a computerized mathematical technique that allows people to account for risk in quantitative analysis and decision making. The technique is used by professionals in such widely disparate fields as finance, project management, energy, manufacturing, engineering, research and development, insurance, oil & gas, transportation, and the environment. 12/4/2015 Vijit Mittal (NBS, Gr.

8 Monte Carlo simulation furnishes the decision-maker with a range of possible outcomes and the probabilities they will occur for any choice of action.. It shows the extreme possibilities—the outcomes of going for broke and for the most conservative decision—along with all possible consequences for middle-of-the-road decisions. The technique was first used by scientists working on the atom bomb; it was named for Monte Carlo, the Monaco resort town renowned for its casinos. Since its introduction in World War II, Monte Carlo simulation has been used to model a variety of physical and conceptual systems. 12/4/2015 Vijit Mittal (NBS, Gr. Noida) 8

9 How Monte carlo simulation works 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. It then calculates results over and over, each time using a different set of random values from the probability functions. Depending upon the number of uncertainties and the ranges specified for them, a Monte Carlo simulation could involve thousands or tens of thousands of recalculations before it is complete. Monte Carlo simulation produces distributions of possible outcome values. 12/4/2015 Vijit Mittal (NBS, Gr. Noida) 9

11 Monte Carlo simulation provides a number of advantages over deterministic, or “single-point estimate” analysis Probabilistic Results. Results show not only what could happen, but how likely each outcome is. Graphical Results. Because of the data a Monte Carlo simulation generates, it’s easy to create graphs of different outcomes and their chances of occurrence. This is important for communicating findings to other stakeholders. Sensitivity Analysis. With just a few cases, deterministic analysis makes it difficult to see which variables impact the outcome the most. In Monte Carlo simulation, it’s easy to see which inputs had the biggest effect on bottom-line results 12/4/2015 Vijit Mittal (NBS, Gr. Noida) 11

12 Scenario Analysis: In deterministic models, it’s very difficult to model different combinations of values for different inputs to see the effects of truly different scenarios. Using Monte Carlo simulation, analysts can see exactly which inputs had which values together when certain outcomes occurred. This is invaluable for pursuing further analysis. Correlation of Inputs. In Monte Carlo simulation, it’s possible to model interdependent relationships between input variables. It’s important for accuracy to represent how, in reality, when some factors goes up, others go up or down accordingly. 12/4/2015 Vijit Mittal (NBS, Gr. Noida) 12

14 Real Options and Decision Trees Decision Tree - Diagram of sequential decisions and possible outcomes Decision trees help companies determine their Options by showing the various choices and outcomes. The Option to avoid a loss or produce extra profit has value. The ability to create an Option thus has value that can be bought or sold. 12/4/2015 14 Vijit Mittal (NBS, Gr. Noida)
