simulation[‚sim·yə′lā·shən] (computer science) The development and use of computer models for the study of actual or postulated dynamic systems. SimulationThe process of representing or modeling a situation.simulation the electronic copying or modelling of unique objects. The most famous sociological application of the term is by BAUDRILLARD (1983). He contends that contemporary society is so thoroughly saturated with electronic models and versions of unique objects that distinctions between reality and fiction are no longer valid. See also AURA, HYPERREALITY.Simulation A broad collection of methods used to study and analyze the behavior and performance of actual or theoretical systems. Simulation studies are performed, not on the real-world system, but on a (usually computer-based) model of the system created for the purpose of studying certain system dynamics and characteristics. The purpose of any model is to enable its users to draw conclusions about the real system by studying and analyzing the model. The major reasons for developing a model, as opposed to analyzing the real system, include economics, unavailability of a “real” system, and the goal of achieving a deeper understanding of the relationships between the elements of the system. Simulation can be used in task or situational training areas in order to allow humans to anticipate certain situations and be able to react properly; decision-making environments to test and select alternatives based on some criteria; scientific research contexts to analyze and interpret data; and understanding and behavior prediction of natural systems, such as in studies of stellar evolution or atmospheric conditions. With simulation a decision maker can try out new designs, layouts, software programs, and systems before committing resources to their acquisition or implementation; test why certain phenomena occur in the operations of the system under consideration; compress and expand time; gain insight about which variables are most important to performance and how these variables interact; identify bottlenecks in material, information, and product flow; better understand how the system really operates (as opposed to how everyone thinks it operates); and compare alternatives and reduce the risks of decisions. The word “system” refers to a set of elements (objects) interconnected so as to aid in driving toward a desired goal. This definition has two connotations: First, a system is made of parts (elements) that have relationships between them (or processes that link them together). These relationships or processes can range from relatively simple to extremely complex. One of the necessary requirements for creating a “valid” model of a system is to capture, in as much detail as possible, the nature of these interrelationships. Second, a system constantly seeks to be improved. Feedback (output) from the system must be used to measure the performance of the system against its desired goal. Both of these elements are important in simulation. See Systems engineering Systems can be classified in three major ways. They may be deterministic or stochastic (depending on the types of elements that exist in the system), discrete-event or continuous (depending on the nature of time and how the system state changes in relation to time), and static or dynamic (depending on whether or not the system changes over time at all). This categorization affects the type of modeling that is done and the types of simulation tools that are used. Models, like the systems they represent, can be static or dynamic, discrete or continuous, and deterministic or stochastic. Simulation models are composed of mathematical and logical relations that are analyzed by numerical methods rather than analytical methods. Numerical methods employ computational procedures to run the model and generate an artificial history of the system. Observations from the model runs are collected, analyzed, and used to estimate the true system performance measures. See Model theory There is no single prescribed methodology in which simulation studies are conducted. Most simulation stuides proceed around four major areas: formulating the problem, developing the model, running the model, and analyzing the output. Statistical inference methods allow the comparison of various competing system designs or alternatives. For example, estimation and hypothesis testing make it possible to discuss the outputs of the simulation and compare the system metrics. Many of the applications of simulation are in the area of manufacturing and material handling systems. Simulation is taught in many engineering and business curricula with the focus of the applications also being on manufacturing systems. The characteristics of these systems, such as physical layout, labor and resource utilization, equipment usage, products, and supplies, are extremely amenable to simulation modeling methods. See Computer-integrated manufacturing, Flexible manufacturing system simulation (simulation, system)Attempting to predict aspects of thebehaviour of some system by creating an approximate(mathematical) model of it. This can be done by physicalmodelling, by writing a special-purpose computer program orusing a more general simulation package, probably still aimedat a particular kind of simulation (e.g. structuralengineering, fluid flow). Typical examples are aircraftflight simlators or electronic circuit simulators. A greatmany simulation languages exist, e.g. Simula.

Imitation; said of a disease or symptom that resembles another, or of the feigning of illness as in factitious illness or malingering. 2. In radiation therapy, use of a geometrically similar radiographic system or computer to plan the location of therapy ports.

The controlled representation of dynamic phenomena, which is used when real world data are either unavailable or performing the actual process is undesirable. Simulations are based on observing other system functions, or by assessing a hypothetical system created from existing data.simulation Medtalk The controlled representation of real world phenomena, used when real world experiences are either unavailable or undesirable; simulations are based on observing other system functions, or by assessing a hypothetical system created from existing data.

SIMULATION, French law. This word is derived from the Latin simul, together. It indicates, agreeably to its etymology, the concert or agreement of two or more persons to give to one thing the appearance of another, for the purpose of fraud. Merl. Repert. h.t.
2. With us such act might be punished by indictment for a conspiracy; by avoiding the pretended contract; or by action to recover back the money or property which may have been thus fraudulently obtained. simulation
SimulationThe use of a mathematical model to imitate a situation many times in order to estimate the likelihood of various possible outcomes. See: Monte Carlo simulation.SimulationThe use of a mathematical model with different values as variables in order to determine the likelihood of a particular outcome. A simulation is run many times (often thousands) in order to find the most likely outcome. Running simulations is important for analysts who, for example, wish to predict a security's future price movements.simulation A mathematical exercise in which a model of a system is established, then the model's variables are altered to determine the effects on other variables. For example, a financial analyst might construct a model for predicting a stock's market price and then manipulate various determinants of the price including earnings, interest rates, and the inflation rate to determine how each of these changes affects the market price.simulation a technique for dealing with complex resource allocation problems which cannot be solved exactly by LINEAR PROGRAMMING or similar analytical methods. The technique involves creating a typical life history of a system to represent the actual problem and its rules of operation. Repeated runs of the simulation, slightly altering the operating rules each time, provides experimentation aimed at discovering methods of improving the performance of the system. Such simulation techniques are frequently employed in examining STOCKHOLDING and QUEUE problems. For example, in simulating a queue problem, such as cars queuing at a petrol-station forecourt, it is possible to note how well existing service facilities are coping with customers and the extent to which existing service capacity is utilized. It is also possible to investigate the effects of such changes as increasing the number of service channels or changing the arrangement of channels to discover ways of improving the performance of the garage.AcronymsSeesimulatorsimulation
