• simulation
  • A representation of a problem, situation in mathematical terms, especially using a computer.
Abstract from DBPedia
    A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning, as in economics. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply not exist. Key issues in modeling and simulation include the acquisition of valid sources of information about the relevant selection of key characteristics and behaviors used to build the model, the use of simplifying approximations and assumptions within the model, and fidelity and validity of the simulation outcomes. Procedures and protocols for model verification and validation are an ongoing field of academic study, refinement, research and development in simulations technology or practice, particularly in the work of computer simulation.

    シミュレーション(英: simulation)は、何らかのシステムの挙動を、それとほぼ同じ法則に支配される他のシステムや計算によって模擬すること。simulationには「模擬実験」や「模擬訓練」という意味もある。 なお、「シュミレーション」は「シミュレーション」の語頭の2音を音位転換させたことによって生じた語形で、誤りとされることが多い。また、同化によって「シミレーション」と発音されることがある。「シミュレイション」と表記することもまれにある。
