The Joint Theater Level Simulation (JTLS®) is used to simulate joint, combined, and coalition civil-military operations at the operational level. Used for civil/military simulations and humanitarian assistance/disaster relief (HA/DR) scenarios, JTLS is an interactive, computer-assisted simulation that models multi-sided air, ground, and naval resources with logistical Special Operation Forces (SOF) and intelligence support. The primary purpose of JTLS is to create a realistic environment in which agency staff can operate as they would within a real-world or operational situation. A training audience conducts a scenario or event to practice their ability to coordinate various staff functions. ==Overview== Development of JTLS began in 1983 as a project funded by the U.S. Readiness Command, the U.S. Army War College, and the U.S. Army Concepts Analysis Agency. JTLS was created and continues to be developed and managed by ROLANDS & ASSOCIATES Corporation (R&A), based at Monterey, California. R&A has provided support to U.S. Joint Staff Directorate for Joint Force Development (J7) management of JTLS and has been actively improving the model since its inception. JTLS is currently used by all U.S. combatant commands, U.S. Services, the Naval Postgraduate School, NATO, and several non-U.S. defense agencies and commercial companies. Planners use JTLS for training support and for mission planning and rehearsals.〔Sloan, T.D. "Repetitive Use of the Joint Theater Level Simulation (JTLS) for Investigation of Headquarters Effectiveness. http://archive.org/stream/repetitiveuseofj00sloa#page/6/mode/2up. 1988.〕 The JTLS model is theater and doctrine independent and does not require knowledge of programming to use effectively. JTLS supports a terrain area of 2,000 by 2,000 nautical miles and also supports operations, such as strategic air and ships, outside this area. Users interact with the model through a graphical user interface that uses an Internet browser to interact with the simulation. JTLS may be operated on a single computer or networked computers at a single location or at multiple distributed sites. Model features include Lanchester attrition algorithms for adjudication of ground force interaction, detailed logistics modeling, and explicit air, ground, and naval unit movement, whether civil or military. The JTLS system is also designed to aid in scenario database preparation and verification, entering simulation directives, and obtaining situational information from graphical map displays, messages, and status reports.〔JTLS Executive Overview. ROLANDS & ASSOCIATES Corporation. http://www.rolands.com/jtls/j_vdds/executive_overview.pdf. 2012.〕 JTLS represents the operational level of civil-military strategies, but also employs significant tactical-level capabilities. JTLS can represent a maximum of ten independent Force Sides, each with individual Side relationships and rules of engagement. Each Side can be assigned unlimited Factions. The simulation supports links to most real-world command and control, communications, computer, and intelligence (C4I) systems. The model has been federated with other models through customized interfaces, including the Joint Conflict and Tactical Simulation (JCATS) developed by Lawrence Livermore National Laboratories. JTLS and JCATS have been integrated within the Joint Multi-Resolution Model (JMRM) Federation as core models. JTLS provides high-level aggregate representation while JCATS provides entity-level representation. To support this federation, JTLS includes an Entity Level Simulation (ELS) component that provides entity templating of its aggregate units to further enhance its capabilities. Both models are High Level Architecture (HLA) compliant. The U.S. Joint Staff Directorate for Joint Force Development (J7) manages the JTLS program. The J7 Configuration Control Board (CCB) controls the software development and enhancement process. JTLS improvements reflect customer, U.S., NATO, and commercial client upgrade requests. However, specific new modeling and system capabilities are the result of CCB decisions that consider the costs and benefits of each improvement. Approved requirements are prioritized and implemented. This variety of guidance provides a continuously moving baseline from which JTLS evolves much faster than similar projects. 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「Joint Theater Level Simulation」の詳細全文を読む スポンサード リンク
