Subscriptions: (mt) Marine Technology is circulated to all members of the Society as a portion of their dues allocation. Non-member subscriptions are $120 annually for the U.S. and possessions; single copies are $35. For international non-members, subscriptions are $130 annually; single copies are $35. (mt) Marine Technology is dedicated to James Kennedy, 1867-1936, marine engineer and longtime member of the Society, in recognition and appreciation of his sincere and generous interest in furthering ship design, shipbuilding, ship operation, and related activities. (from the editorial board ) April 2012 It can be argued that modeling and simulation has always been a cornerstone of our industry. Our identity as naval architects came about as a result of our ability to model the behav -ior of vessels at sea. is issue of ( mt) demonstrates that ability in many forms, beginning with (or ending with, given that it?s on page 75) our Historical Note describing the French model basin experiments of 1775-1778. And one of our MT Note entries explores how there has been a fundamental shift in the evolving landscape of ship hydrodynamics so central to the profession. Our modeling and simulation toolkit today is very diverse, touching nearly every associated engineering discipline. As these capabilities have become more aordable, and as the time required to employ them has become more compatible with schedule constraints, modeling and simulation have been used more regularly to reduce risk and enable greater technical innovation. We?re pleased to oer in-depth information on these tools and capabilities. Learn how Newport News Shipbuilding combines modeling and simulation technology with real-world testing to reduce risk and to innovate on the next-generation aircraft carrier. Read about the ways in which modeling pedestrian dynamics is even enabling safer and faster evacuation of passengers, and see why a simplied re spread model, integrated with CFD tools, can enable assessment of material ame spread potential. You?ll also discover how modeling and simu -lation are used to predict noise and vibration, and how Samsung Heavy Industries employs lighting modeling and simulation in their designs. We also look at how naval engineers are using modeling and simulation to assess ship sur -vivability, enabling more innovative and cost-eective solutions. With this increasing diversity of capabilities comes the challenge of integrating these capabilities eectively?a challenge the United States Navy is tackling with LEAPS, which integrates design and analysis tools into an automated high-end toolset. Modeling and simulation also are being employed to answer broader programmatic questions and to address cost, as you?ll discover in our examination of how the Port of Long Beach uses modeling as a key part of successful expansion. It is impossible to do justice to the topic in a single issue. But we hope that what you?ll nd here provides you with improved insight into the emerging state of the art and enables you to identify areas in which modeling and simulation might be leveraged into your own projects .Norbert Doerry and Matthew P. Tedesco SNAME (mt) Editorial Board Dr. Norbert Doerry is the technical director of the Naval Sea Systems Command SEA 05 Technology Oce. Following 26 years of com -missioned service, he retired from the United States Navy in 2009 as an engineering duty captain. He served in his nal billet for nearly six years as the technical director for surface ship design. He graduated from the United States Naval Academy and earned his PhD from MIT. Dr. Doerry is a recipient of the ASNE Gold Medal and the ASNE Jimmie Hamilton Award. He has published more than 30 technical papers and technical reports. Dr. Matthew Tedesco is a technical and management consultant with more than 20 years of experience in the marine industry. Recent projects have related to total ownership cost reduction, modeling and simulation, economic modeling, decision analysis, cargo handling research and development, business case development, and marine highways feasi -bility. Prior to starting his consultancy in 2001, he was a GD-NASSCO employee. Matt is an aliate of Maritime Transport and Logistics Advisors, LLC. He is the Pacic vice-chair of SNAME Panel O-36 (Maritime Economics), and a member of the ( mt) magazine editorial board. He is also a member of ASNE.
