1. A description of observed or predicted behaviour of some system, simplified by ignoring certain details. Models allow complex systems, both existent and merely specified, to be understood and their behaviour predicted. A model may give incorrect descriptions and predictions for situations outside the realm of its intended use. A model may be used as the basis for simulation.Note: British spelling: "modelling", US: "modeling".
