and has defined the following set of model enterprise processes: simulation-based acquisition, agile commerce, real-time logistics management, resource planning, dynamic mission planning, and system of systems.

Simulation-Based Acquisition

Description of the Technology

Simulation-based acquisition (SBA) is a potentially revolutionary process for the acquisition of complex platforms or systems. It integrates all acquisition activities starting with requirements definition through production, deployment, and operational support into a computational network with a common database. This integrated approach enables the optimization of design, manufacturing, and life-cycle support functions associated with complex systems. At the initiation of a proposed SBA procurement, government and industry teams will create virtual prototypes of candidate systems that could include warships, aircraft, communications systems, logistic systems, information systems, or other complex systems. These virtual prototypes will be fully linked to an integrated product database and are used by all participants during acquisition, development, and operation throughout the life cycle of the products. SBA is based on a computer environment that integrates existing models and simulations (and new ones if required), engineering and physics, and operations and doctrine to evaluate overall product value and cost, to guide the development process, and to support operation of the product during its service life. Figure 10.1 shows a schematic representation of the SBA process.

SBA comprises an advanced scalable architecture, an integrated product database that includes product attributes; an interactive, immersive synthetic environment; integrated collaboration tools; analysis and modeling tools packaged with standard, interoperable interfaces; smart agents to assist in information collection and integration; and advanced product and process-optimization tools.

Relevance to the Naval Forces

SBA allows decisionmakers the unprecedented ability to examine design and operational issues for proposed systems by interacting with the virtual prototype of the product. High-fidelity simulations allow acquisition authorities to visualize and analyze the virtual prototype in distinct phases of its life cycle. Virtual prototypes allow officials to "fly before you build" to examine alternative designs, performance, and cost. They are thus able to conduct studies that include mission value, affordability, performance tradeoffs, manning, maintenance, and the like. Government and industry personnel work together to build the right product, the right way, at the right price, on schedule.
