Proceedings of the Third International Defense and Homeland Security Simulation Workshop, DHSS 2013

WELCOME TO DHSS 2013! We extend our most sincere welcome to all attendees of this year's 2013 International Defense and Homeland Security Simulation Workshop being held in beautiful Athens, Greece. Simulation in Defense and Homeland Security is becoming more important and pervasive due to opportunity to use Modeling & Simulation (M&S) approaches combined with new technologies (i.e. mobile technologies) across the whole spectrum of military operations. Indeed while training and decision support are the traditional application areas for M&S in the Defense and Homeland Security domains, new opportunities arise in which M&S can be profitably used to validate innovative concepts: design and acquisition of new systems and technologies, interaction between human and autonomous systems, advanced human behavior modeling, systems and networks integrations to cite a few. As in the past, the DHSS workshop has included a diversity of topics presented by authors from many different institutions. This brings a plurality of interests and perspectives to a single location. Making the event even more compelling is the partnership within I3M (The International Multidisciplinary Modeling and Simulation Multiconference) which allows for even more cross pollination (this year I3M includes 7 international conferences/workshops). We hope you take advantage of this opportunity and contribute, through presentations, discussion and interaction, to the development of new ideas and new directions in research and applied technology. In addition to the many technical sessions, there is always the opportunity to share ideas and discuss approaches during the breaks and on the sidelines. We hope you find the DHSS Workshop and the I3M multi-conference, including the keynote speakers, the technical sessions and other program events educational and interesting. Our thanks go out to all the authors, to the papers reviewers and the keynote speakers who have helped to make this year's Workshop a success. We wish you a very successful workshop and we hope you will enjoy Greece, the birthplace of Democracy and Philosophy, as well as Athens, one of the oldest city in the world with more than 3000 years of history.
