A Shift from Model-Based to Simulation-Based Paradigm: Timeliness and Usefulness for Many Disciplines

Model-based paradigm has been adopted by a number of disciplines since its introduction in the late 70s. After a brief history on how model-based approach started in simulation, the merit and the spread of the model-based approach are described. The concept of model is subsumed in simulation, but many times employing just the model-based approach does not involve simulation. The superiority and advantages of simulation-based approach over model-based approach are manifold. This article describes the differences and advocates the use of simulation-based paradigm in advancing any computational discipline.
