Grand challenges on the theory of modeling and simulation

Modeling & Simulation (M&S) is used in many different fields and has made many significant contributions. As a field in its own right, there have been many advances in methodologies and technologies. In 2002 a workshop was held in Dagstuhl, Germany, to reflect on the grand challenges facing M&S. Ten years on, a series of M& S Grand Challenge activities are marking a decade of progress and are providing an opportunity to reflect and plan for the future. This second Grand Challenge Panel brings together a new set of experts from both industry and academia to reflect on M&S Grand Challenges. Themes include big simulation, coordinated modeling, large scale systems modeling, human behavioral modelling, composability, funding availability, cloud-based M&S, engineering replicability into computational models, democratization of M&S, multi-domain design, executing and targeting hardware platforms and education. It is hoped that these activities will provide inspiration to those already working in or with M&S and those just beginning their career.
