本推荐规程定义了使用高级体系结构（HLA）联邦开发和执行过程（FEDEP）开发的联邦实施验证、确认和认可（VV&A）时应遵循的流程和程序。本推荐做法的目的不是取代现有的VV&A政策、程序和指南，而是着眼于联盟VV&A的独特方面。它提供了一个更高级别的框架，可以将这些实践集成到其中，并针对特定用途进行定制。VV&A覆盖为VV&A从业者提供实施层面的指导； 然而，它没有描述可能用于执行联邦VV&A过程的个别技术。 这个VV＆A覆盖集中在适用于联邦的VV＆A过程，而不是与单个模拟（联邦成员）相关联的VV＆A过程，而是考虑使用这些进程所产生的信息。 使用非基于HLA和FEDEP的仿真和仿真组合的用户、开发人员和VV&A人员也可以受益于本文档中的指导，因为该叠加描述的活动可以定制为支持任何类型的分布式仿真应用。

This recommended practice defines the processes and procedures that should be followed to implement Verification, Validation, and Accreditation (VV&A) for federations being developed using the High Level Architecture (HLA) Federation Development and Execution Process (FEDEP). This recommended practice is not intended to replace existing VV&A policies, procedures, and guidance, but rather is intended to focus on the unique aspects of the VV&A of federations. It provides a higher-level framework into which such practices can be integrated and tailored for specific uses. The VV&A overlay provides implementation-level guidance to VV&A practitioners; however, it does not describe the individual techniques that might be employed to execute the VV&A processes for federations. This VV&A overlay focuses upon the VV&A processes that apply to federations and not the VV&A processes associated with individual simulations (federates), but does consider using the information produced by those processes. Users, developers, and VV&A personnel working with simulations and simulation compositions not based upon the HLA and the FEDEP can also benefit from the guidance in this document since the activities that this overlay describes can be tailored to support any type of distributed simulation application.
