Abstract
We are interested in the multi-modeling and simulation of complex systems, that is representing a complex system as a set of interacting models and simulating it with a co-simulation approach. Representing and simulating a complex system multi-model requires to integrate heterogeneity at several levels (representations, formalisms, simulation software, models' interactions. . .). In this article, we present our approach that consists of combining the Discrete EVent System Specification (DEVS) formalism and multi-agent concepts in order to achieve these requirements. The use of the DEVS formalism enables a rigourous integration of models described with heterogeneous formalisms and a rigourous simulation protocol. Multi-agent concepts ease the description of multi-perspective integration and the reuse of existing heterogeneous simulators. We detail the combination of both in the Agent & Artifact for Multi-Modeling (AA4MM) approach and illustrate its use in a proof of concept.
