Simulation Versus Model
A computer model refers to the algorithms and equations used to capture the behavior of the system being modeled. However, a computer simulation refers to the actual running of the program which contains these equations or algorithms. Simulation, therefore, refers to an instance where you ran a model. In other words, you wouldn't "build a simulation" you would "build a model", but you could either "run a model" or "run a simulation". Model and simulation are often used interchangeably and the difference between them is trivial.

Famous quotes containing the words simulation and/or model:
“Life, as the most ancient of all metaphors insists, is a journey; and the travel book, in its deceptive simulation of the journey’s fits and starts, rehearses life’s own fragmentation. More even than the novel, it embraces the contingency of things.”
—Jonathan Raban (b. 1942)
“If the man who paints only the tree, or flower, or other surface he sees before him were an artist, the king of artists would be the photographer. It is for the artist to do something beyond this: in portrait painting to put on canvas something more than the face the model wears for that one day; to paint the man, in short, as well as his features.”
—James Mcneill Whistler (1834–1903)
