Modeling and Simulation of Complex Systems: Pitfalls and Limitations of Interpretation
Dominique Luzeaux · 2013
This chapter discusses the way in which certain formal aspects inherent in modeling techniques can, and must, be considered when interpreting the results of a simulation, particularly in relation to their generality and generalization, that is, their validity outside of the domain initially considered. Great care is required when using simulation results, especially when considering global (or globalizing) properties. The chapter demonstrates the need for a common vocabulary and the value of introducing the issue from an original angle. Next, the main characteristics of complex systems simulation are discussed. The chapter provides a review of families of models. The two main opposing approaches in mathematical modeling techniques are equational and computational approaches. The real choice of an approach to consider in a given context depends more on the availability of modeling and resolution tools rather than on an a priori analysis of different approaches.
