Model-Based Activities: A Paradigm Shift

The aim of this chapter is to explore the possibilities to place simulation in a central position for several scientific disciplines. The following topics are discussed: 1)A proposed shift of paradigm in simulation,2)Fundamental elements of a simulation study,3)Models and behavior,4)Synergies of simulation, software engineering, artificial intelligence, and general system theories,5)Elements of a model-based simulation software system,6)Knowledge-based modelling and simulation systems,7)Highlights of desirable research directions in simulation methodology and software.
