Modeling & Simulation

M&S Information Management

Effective acquisition requires collaboration among multiple Stakeholders. Modeling & Simulation (M&S) tools combined with an information-sharing infrastructure (i.e., integrated data environment – IDE) into a distributed collaborative environment can enable cost-effective development and sustainment of systems and systems of systems. [1]

M&S should share the common information base with the rest of Systems Engineering. The IDE should allow data producers to publish their data items and record required metadata. Metadata is critical to the discovery and understanding of functions. It should also allow data consumers, from their desktop, to readily discover (via browsing and searching), access (via proper access controls), understand, and download the data they need, and have an archiving capability so that the program can, at any future time, identify the information set that was used to inform a decision. [1]


The metadata that accompanies each data item should provide the information needed to understand its structure, lineage, and meaning, including its context and applicability. This same metadata will facilitate Verification, Validation & Accreditation (VV&A) and will allow the data it describes to be transformed into the form needed by the consuming M&S tool. Particular sets of data items will describe the system at a particular point in its development and as such will inform program events and provide the information foundation for program activities, including M&S-based analyses.
