Purdue University's Synthetic Environment for Analysis and Simulations, or ( SEAS ), is currently being used by Homeland Security and the US Defense Department to simulate crises on the US mainland.〔 (The Register ) article ''Sentient world: war games on the grandest scale'' published June 23, 2007〕 SEAS "enables researchers and organizations to try out their models or techniques in a publicly known, realistically detailed environment."〔(SEAS )〕 It "is now capable of running real-time simulations for up to 62 nations, including Iraq, Afghanistan, and China. The simulations gobble up breaking news, census data, economic indicators, and climactic events in the real world, along with proprietary information such as military intelligence. () The Iraq and Afghanistan computer models are the most highly developed and complex of the 62 available to JFCOM-J9. Each has about five million individual nodes representing things such as hospitals, mosques, pipelines, and people."〔 SEAS was developed to help Fortune 500 companies with strategic planning. Then it was used to help "recruiting commanders to strategize ways to improve recruiting potential soldiers". In 2004 SEAS was evaluated for its ability to help simulate "the non-kinetic aspects of combat, things like the diplomatic, economic, political, infrastructure and social issues".〔 (Purdue University ) article ''USJFCOM teams with Purdue University to add the human factor to war game simulations'' published February 6, 2004〕 Sentient World Simulation is the name given to the current vision of making SEAS a "continuously running, continually updated mirror model of the real world that can be used to predict and evaluate future events and courses of action."〔 (Purdue University ) abstract from Alok Chaturvedi titled ''Computational Challenges for a Sentient World Simulation'' published March 10, 2006〕 ==Development and use== SEAS technology resulted from over ten years of research at Purdue University, funded by the Department of Defense, several Fortune 500 companies, the National Science Foundation, the (Century Fund of the state of Indiana ), and the Office of Naval Research. Originally, SEAS was developed to help Fortune 500 companies with strategic planning. It was also used to model the population of the U.S. that is eligible for military service to help "recruiting commanders to strategize ways to improve recruiting potential soldiers"〔 and to study biological attacks.〔 (Purdue University ) article ''Indiana researchers tap into grid computing to prepare for disasters'' published June 24, 2002〕 In January 2004 SEAS was evaluated by the Joint Innovation and Experimentation Directorate (J9) of the US Joint Forces Command (JFCOM) for its ability to help simulate "the non-kinetic aspects of combat, things like the diplomatic, economic, political, infrastructure and social issues" at the Purdue Technology Park during Breaking Point 2004, an environment-shaping war game resulting in the conclusion that it "moves us from the current situation where everyone comes together and sits around a table discussing what they would do, to a situation where they actually play in the simulation and their actions have consequences."〔 In 2006 JFCOM-J9 used SEAS to war game warfare scenarios for Baghdad in 2015. In April 2007 JFCOM-J9 began working with Homeland Security and multinational forces in a homeland defense war gaming exercise.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Synthetic Environment for Analysis and Simulations」の詳細全文を読む スポンサード リンク
