“…Another effect that agent research has had on modeling and simulation methods has been in the context of model composition and simulation interoperation (Tolk, 2006;Yilmaz and Tolk, 2006). Current simulation protocols are focused on the definition of standardized information exchange, like Protocol Data Units in IEEE1278 (of Electrical and Engineers) or Federation Object Models in IEEE1516 (of Electrical and Engineers).…”

“…The impact that agents have on modeling and simulation is manifold and has been subject to a series of explorations, for example, Yilmaz and Tolk, 2006;Uhrmacher and Röhl, 2007;Uhrmacher and Weyns, to appear 2008). Agents are used as a metaphor for modeling, as a programming metaphor to design distributed simulation systems, and simulation is used for a better understanding of multiagent system behavior and for designing and evaluating software agents.…”

“…Broker and matchmaker agents select and update collaboratively the producers and consumers of data in a common workflow as cooperative partners. The idea of introspection, the seamless and transparent update of behavior of the simulation system -who is doing what, when, where, why, and how -by representing agents, plays a pivotal role and was first published by Yilmaz (2004) and updated by Yilmaz and Tolk (2006). It was recently extended in support of autonomic introspective simulation Systems by Yilmaz and Mitchell (2008).…”

Ambassador agents represent simulation services that are candidates to contribute to the solution of a problem. They need to know and express enough about the simulations to negotiate with other ambassador agents if the represented simulation systems can be composed to contribute to the solution. A formal approach to simulation interoperability based on set theory and date modeling theory was developed. The formal model of data in M&S capturing possible representations of real or imagined things in the world including definitions for existential and transformational dependencies is presented. Existential dependencies capture the relationships within a model while transformational dependencies capture the relationships between interactions with a model. These definitions are used to formally specify interoperation, the ability to exchange information, as a necessary condition for interoperability. The elements needed for a language needed for ambassador agents are derived using the formal approach to interoperability. INTRODUCTIONThis paper is composing three research domains supported by the authors and merges them into a common application, namely a theory, an engineering method, and the use of agents.• The topic of composability of models and interoperability of simulations resulted in the development of the Levels of Conceptual Interoperability Model (LCIM), which was first introduced in (Tolk and Muguira 2003) and has been continuously evolved using feedback from other experts in various application domains to its current form, as described in ). • Using the theoretic insights from this model, the engineering method Model-based Data Engineering (MBDE) was developed to support heuristics that can be applied by systems engineers and federation developers to achieve the goal of composing model-based solutions (Tolk and Diallo 2005). • By developing a formal approach to simulation interoperability and capturing the formalism using mathematically precise terms, the development of profiles is supported that now allows the application of Agent-Directed Simulation (ADS) to support the composition. Using the meta-data of the profile, agents become ambassadors for the model-based solution and can negotiate their composition with other solutions in support of a research question.This paper uses many of the groundbreaking ideas on agent-based mediated solutions that so far were missing a common component of a formal approach to interoperability. This component should allow the profiling of a model-based solution, the measurement of the semantic distance between alternatives as well as the measurement of the distance between required capability and provided functionality, and a 359 978-1-4244-9865-9/10/$26.00 ©2010 IEEE

“…Relevant models need to be identified and instantiated to continue exploration. Manual exploration is not cost effective and realistic within a large problem state space (Yilmaz and Tolk 2006). Our knowledge about the problem being studied may not be captured by any single model or experiment (Bankes 1999).…”

“…Adaptivity in simulations and scenarios is necessary to deal with emergent conditions for evolving systems in a flexible manner. As simulations of complex phenomena are more and more used to aid intuition, dynamic run-time simulation composition with exploratory simulation will help identify (re)solution strategies that are flexible, adaptive, and robust (Yilmaz and Tolk 2006). In symbiotic simulation (Fujimoto et al 2002) as well the problems advocated by the NSF DDDAS program, information about the actual performance and accuracy characteristics of the system are acquired during actual simulation rather than before.…”

The significance of simulation modeling at multiple levels, scales, and perspectives is well recognized. However, existing proposals for developing such models are often application specific. The position advocated in this paper is that generic design principles for specifying and realizing multiresolution, multistage models are still lacking. Requirements for simulation environments that facilitate multiresolution multistage model specification are introduced. A multimodel specification formalism based on graph of models is suggested along with design precepts to enable flexible dynamic model updating. The notion of multisimulation is introduced to enable exploratory simulation using various types of multimodels.
