Modeling Agents and their Environment in Multi-Level-DEVS

In: Proceedings of the 2012 Winter Simulation Conference, ed. by C. Laroque and J. Himmelspach and R. Pasupathy and A. M. Uhrmacher and O. Rose, Piscataway, New Jersey, USA, Institute of Electrical and Electronics Engineers, Inc.

Environments play an important role in multi-agent systems. They present the context agents operate in. When testing multi-agent systems by simulation, the environment and partly agents have to be modeled. We explore the potential of Multi-Level-DEVS to serve as a modeling formalism for agents, their environment, and the interaction between them. Multi-Level-DEVS combines a modular, hierarchical modeling with variable structures, dynamic interfaces, and explicit means for describing up- and downward causation between different levels of the compositional hierarchy. The modeling in Multi-Level-DEVS emphasizes the role of the environment to provide information for and enforce constrains on the situated agents. A smart meeting room scenario is modeled, and an approach aimed at recognizing user activities in smart environments is tested and evaluated in a simulation study.
