A comprehensive and detailed verification, validation, and accreditation (VV&A) plan and its proper execution are crucially important for the successful accreditation of a modeling and simulation (M&S) application. We provide guidance in developing and executing such a plan throughout the entire M&S application development life cycle.
Many different types of modeling and simulation (M&S) applications, consisting of a combination of software, hardware, and humanware, are used in dozens of disciplines under diverse objectives including acquisition, analysis, education, entertainment, research, and training. Certification of sufficient accuracy of an M&S application by conducting(More)
Reusability and composability (R&C) are two important quality characteristics that have been very difficult to achieve in the Modelling and Simulation (M&S) discipline. Reuse provides many technical and economical benefits. Composability has been increasingly crucial for M&S of a system of systems, in which disparate systems are composed with each other.(More)
A modeling and simulation (M&S) application is built for a specific purpose and its acceptability assessment is carried out with respect to that purpose. The accreditation decision for an M&S application is also made with respect to that purpose. The purpose is commonly expressed in terms of "intended uses." The quality of expressing the intended uses(More)
