Abstract for: Bridging Modeling Methods: A Formalism to Specify Hybrid Simulation Models on the Conceptual Level

Hybrid simulation modeling, i.e., combining two or more simulation methods to form a single model, gains growing attention within the simulation community. In its practical application, hybridization can result in better decisions than single-paradigm approaches. However, it is not the lack of implementation tools but mainly the lack of a commonly accepted standard for conceptual modeling that hinders a broader acceptance of hybrid simulation models. We fill the existing gap by presenting a formalism to specify hybrid models on the conceptual level. Our hybrid agent-based modeling and simulation (HABM) formalism supports the combination of agent-based modeling and simulation, discrete event simulation, and system dynamics as well as dynamic model structures. We apply the formalism to a queueing system example. Our formalism offers some new research opportunities.
