Not to be confused with Stimulation. Simulation is the imitation of the operation of a real-world process or system. Simulation is used in many contexts, such as simulation of technology for performance urban forex support and resistance strategy game, safety engineering, testing, training, education, and video games. Key issues in simulation include acquisition of valid source information about the relevant selection of key characteristics and behaviours, the use of simplifying approximations and assumptions within the simulation, and fidelity and validity of the simulation outcomes.
Visualization of a direct numerical simulation model. Historically, simulations used in different fields developed largely independently, but 20th century studies of systems theory and cybernetics combined with spreading use of computers across all those fields have led to some unification and a more systematic view of the concept. Interactive simulation is a special kind of physical simulation, often referred to as a human in the loop simulation, in which physical simulations include human operators, such as in a flight simulator or a driving simulator. Continuous simulation is a simulation where time evolves continuously based on numerical integration of Differential Equations. Deterministic Simulation is a simulation where the variable are regulated by deterministic algorithms, so replicated runs from same boundary conditions produce always identical results. Stand Alone Simulation is a Simulation running on a single workstation by itself.
Simulation as a Service where Simulation is accessed as a Service over the web. Simulation Fidelity is used to describe the accuracy of a simulation and how closely it imitates the real-life counterpart. Fidelity is broadly classified as 1 of 3 categories: low, medium, and high. Human in the loop simulations can include a computer simulation as a so-called synthetic environment.
This was the best and fastest method to identify the failure cause. By changing variables in the simulation, predictions may be made about the behaviour of the system. It is a tool to virtually investigate the behaviour of the system under study. Traditionally, the formal modeling of systems has been via a mathematical model, which attempts to find analytical solutions enabling the prediction of the behaviour of the system from a set of parameters and initial conditions. Modern usage of the term “computer simulation” may encompass virtually any computer-based representation.
