Encyclopedia Article for simulations

simulation

in industry, science, and education, a research or teaching technique that reproduces actual events and processes under test conditions. Developing a simulation is often a highly complex mathematical process. Initially a set of rules, relationships, and operating procedures are specified, along with other variables. The interaction of these phenomena create new situations, even new rules, which further evolve as the simulation proceeds. Simulation implements range from paper-and-pencil and board-game reproductions of situations to complex computer-aided interactive systems
