Live, Virtual, and Constructive (LVC) Simulation is a broadly used taxonomy for classifying Models and Simulation (M&S). However, categorizing a simulation as a live, virtual, or constructive environment is problematic since there is no clear division between these categories. The degree of human participation in a simulation is infinitely variable, as is the degree of equipment realism. The categorization of simulations also lacks a category for simulated people working real equipment.〔"DoD Modeling and Simulation (M&S) Glossary", DoD 5000.59-M, DoD, January 1998 ()〕 ==Categories== The LVC categories as defined by the United States Depart of Defense in the Modeling and Simulation Glossary as follows: * Live - A simulation involving real people operating real systems. Military training events using real equipment are live simulations. They are considered simulations because they are not conducted against a live enemy. * Virtual - A simulation involving real people operating simulated systems. Virtual simulations inject a Human-in-the-Loop into a central role by exercising motor control skills (e.g., flying jet or tank simulator), decision making skills (e.g., committing fire control resources to action), or communication skills (e.g., as members of a C4I team). * Constructive - A simulation involving simulated people operating simulated systems. Real people stimulate (make inputs) to such simulations, but are not involved in determining the outcomes. A constructive simulation is a computer program. For example, a military user may input data instructing a unit to move and to engage an enemy target. The constructive simulation determines the speed of movement, the effect of the engagement with the enemy and any battle damage that may occur. These terms should not be confused with specific constructive models such as Computer Generated Forces (CGF), a generic term used to refer to computer representations of forces in simulations that attempts to model human behavior. CGF is just one example model being used in a constructive environment. There are many types of constructive models that involve simulated people operating simulated systems. Other associated terms are as follows: * LVC Enterprise - The overall enterprise of resources in which LVC activities take place. * LVC Integration - The process of linking LVC simulations through a suitable technology or protocol to exploit simulation interoperability within a federated simulation environment such as the high level architecture (simulation) or Eurosim.〔"Policy, information and guidance on the Modelling and Simulation aspects of UK MOD Defence Acquisition version 1.0.3 - May 2010", ()〕〔http://www.eurosim.info/〕 * LVC Integrating Architecture (LVC-IA) - The aggregate representation of the foundational elements of a LVC Enterprise, including hardware, software, networks, databases and user interfaces, policies, agreements, certifications/accreditations and business rules. LVC-IA is intrinsically an Enterprise Architecture, given the system-of-systems environment it must support. LVC-IA bridges M&S technology to the people who need and use the information gained through simulation. To accomplish this a LVC-IA provides the following: : * Integration through simulation equipment, interoperability tools and support personnel. See also Enterprise integration and Enterprise architecture. Integration creates network-centric linkages to collect, retrieve and exchange data among live instrumentation, virtual simulators and constructive simulations as well as between the joint military and specific service command systems. Integration also bridges together data management, exercise management, exercise collaboration and updating training support systems. : * Interoperability through common protocols, specifications, standards and interfaces to standardize LVC components and tools for mission rehearsals and training, testing, acquisition, analysis, experimentation, and logistics planning. : * Composability through common and reusable components and tools such as enterprise after action review, adapters, correlated terrain databases, Multilevel security for multinational players and hardware/software requirements.
