Models and Reality: Some Reflections on the Art and Science of Simulation
This paper presents a philosophical overview of simulation, with an emphasis on the nature of the relation between models and the systems they represent. Model-making is shown to be an essential feature of human thinking. The “abstraction ladder,” which leads from observations of reality to mathematical models, is reviewed from a semantic viewpoint. The problem of validation of the results of a simulation is then outlined. The paper concludes with same philosophical observations on the relation of model and reality.
