Verification Validation and Accreditation

Verification, Validation, and Accreditation (VV&A) are three interrelated but distinct processes that gather and evaluate evidence to determine whether a model or simulation should be used in a given situation and establishing its credibility. The decision to use the simulation will depend on the simulation’s capabilities and correctness, the accuracy of its results, and its

Simulation Based Acquisition (SBA)

  Simulation-Based Acquisition (SBA) is the robust and interactive use of Modeling & Simulation (M&S) throughout the product life cycle. The Program Manager (PM) should employ SBA and M&S during system design, test and evaluation, and modification and upgrade. The PM should collaborate with operational users and consider industry inputs during SBA/M&S program planning. Planning

Human-in-the-Loop (HTL)

Human-in-the-Loop (HITL) Modeling & Simulation (M&S) is a model type that requires human interaction during runtime. It employs one or more human operators in direct control of the simulation/simulator or in some key support function. Human-centered M&S is distinguished from science and process-based simulations where human intervention and modeling does not occur. [1] Human-in-the-Loop lends
