## Monte Carlo Simulation

Risk analysis is part of every decision we make. We are constantly faced with uncertainty, ambiguity, and variability. 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. 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.

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. By using probability distributions, variables can have different probabilities of different outcomes occurring. Probability distributions are a much more realistic way of describing uncertainty in variables of a risk analysis.

Values in the middle near the mean are most likely to occur. Examples of variables described by normal distributions include inflation rates and energy prices. Values are positively skewed, not symmetric like a normal distribution. Examples of variables described by lognormal distributions include real estate property values, stock prices, and oil reserves.

All values have an equal chance of occurring, and the user simply defines the minimum and maximum. Examples of variables that could be uniformly distributed include manufacturing costs or future sales revenues for a new product. The user defines the minimum, most likely, and maximum values. Values around the most likely are more likely to occur.

Variables that could be described by a triangular distribution include past sales history per unit of time and inventory levels. The user defines the minimum, most likely, and maximum values, just like the triangular distribution. However values between the most likely and extremes are more likely to occur than the triangular; that is, the extremes are not as emphasized. An example of the use of a PERT distribution is to describe the duration of a task in a project management model.

The user defines specific values that may occur and the likelihood of each. During a Monte Carlo simulation, values are sampled at random from the input probability distributions. Each set of samples is called an iteration, and the resulting outcome from that sample is recorded.

Monte Carlo simulation does this hundreds or thousands of times, and the result is a probability distribution of possible outcomes. In this way, Monte Carlo simulation provides a much more comprehensive view of what may happen.

It tells you not only what could happen, but how likely it is to happen. An enhancement to Monte Carlo simulation is the use of Latin Hypercube sampling, which samples more accurately from the entire range of distribution functions.

The advent of spreadsheet applications for personal computers provided an opportunity for professionals to use Monte Carlo simulation in everyday analysis work. First introduced for Lotus for DOS in , RISK has a long-established reputation for computational accuracy, modeling flexibility, and ease of use.

What is Monte Carlo Simulation? 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.

Lognormal Values are positively skewed, not symmetric like a normal distribution. Uniform All values have an equal chance of occurring, and the user simply defines the minimum and maximum.

Triangular The user defines the minimum, most likely, and maximum values. PERT The user defines the minimum, most likely, and maximum values, just like the triangular distribution. Discrete The user defines specific values that may occur and the likelihood of each. Results show not only what could happen, but how likely each outcome is. Graphical Results. 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. 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.

It seems that you're in Germany. We have a dedicated site for Germany. This textbook introduces modern techniques based on computer simulation to study materials science. It starts from first principles calculations enabling to calculate the physical and chemical properties by solving a many-body Schroedinger equation with Coulomb forces. For the exchange-correlation term, the local density approximation is usually applied.

Exploring Monte Carlo Methods is a basic text that describes the numerical methods that have come to be known as "Monte Carlo. The next two chapters focus on applications in nuclear engineering, which are illustrative of uses in other fields. Five appendices are included, which provide useful information on probability distributions, general-purpose Monte Carlo codes for radiation transport, and other matters. This book provides the basic detail necessary to learn how to apply Monte Carlo methods and thus should be useful as a text book for undergraduate or graduate courses in numerical methods.

Monte Carlo methods , or Monte Carlo experiments , are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results. The underlying concept is to use randomness to solve problems that might be deterministic in principle. They are often used in physical and mathematical problems and are most useful when it is difficult or impossible to use other approaches.

После многочасовых поисков ее обнаружил младший лаборант. То была моль, севшая на одну из плат, в результате чего произошло короткое замыкание. Тогда-то виновников компьютерных сбоев и стали называть вирусами.

Он никогда не получит Сьюзан Флетчер. Никогда. Внезапная пустота, разверзшаяся вокруг него, была невыносима. Яростная волна гнева захлестнула. Она снова услышала голос Дэвида: Я люблю. Беги.

Двадцать миллионов долларов - это очень большие деньги, но если принять во внимание, за что они будут заплачены, то это сущие гроши. ГЛАВА 19 - А вдруг кто-то еще хочет заполучить это кольцо? - спросила Сьюзан, внезапно заволновавшись.  - А вдруг Дэвиду грозит опасность. Стратмор покачал головой: - Больше никто не знает о существовании кольца. Именно он принимал ее на работу, именно он сделал АНБ для нее родным домом. Когда десять лет назад Сьюзан поступила в агентство, Стратмор возглавлял Отдел развития криптографии, являвшийся тренировочной площадкой для новых криптографов, криптографов мужского пола.

Monte Carlo methods are defined broadly as a statistical approach to provide approximate solutions to mathematically complex optimization or simulation problems by using random sequences of numbers.
