Learn more about Simulation
Simulation is a tool to better understand and optimize performance or reliability of systems, simulation is also extensively used to verify the correctness of designs. Most if not all digital integrated circuits manufactured today are first extensively simulated before they are manufactured to identify and correct design errors. Simulation early in the design cycle is important because the cost to repair mistakes increases dramatically the later in the product life cycle that the error is detected. Training Simulations Another important application of simulation is in developing "virtual environments" , e.g., for training. Simulations generate dynamic environments with which users can interact "as if they were really there." Such simulations are used extensively today to train for example military personnel for battlefield situations, but are also increasingly used in business settings. System Simulation is the mimicking of the operation of a real system, such as the day-to-day operation of a bank, or the value of a stock portfolio over a time period, or the running of an assembly line in a factory, or the staff assignment of a hospital or a security company, in a computer. Instead of building extensive mathematical models by experts, the readily available simulation software has made it possible to model and analyze the operation of a real system by non-experts, who are managers but not programmers. Simulation has become an effective decision support for managers In the field of simulation, the concept of "principle of computational equivalence" has beneficial implications for the decision-maker. Simulated experimentation accelerates and replaces effectively the "wait and see" anxieties in discovering new insight and explanations of future behavior of the real system. With the integration of artificial intelligence, agents and other modeling techniques, simulation has become an effective and appropriate decision support for managers. For example, in a consumer retail environment it can be used to find out how the roles of consumers and employees can be simulated to achieve peak performance.
