Proceedings of the Symposium on Simulation for Architecture & Urban Design

Welcome to the Spring Simulation Multi-Conference 2013 (SpringSim'13) in San Diego, CA. As the General Chair of this year's SpringSim, it is an honor and privilege to be your host for these exciting four days of activities driven and organized by the various members of our society. Despite challenges in the worldwide economy and the overall decrease of funding for travel and conferences, the interest in Modeling and Simulation (M&S) and its applications is still high enough to ensure a challenging and interesting program. From the opening tutorial day where international experts are providing their knowledge to our community to the presentation of peer-reviewed papers, invited special topic presentations, and expert panel discussions the chairs of our symposia did their best to provide an outstanding choice. Without the work of these volunteers, SpringSim would not have been possible.
