Modeling & Simulation
Abstract
The mission of the Agency`s Modeling and Simulation (M&S) program is to engineer and deliver validated, integrated simulation solutions for the primary uses of BMDS Performance Assessment and Ground Test, with additional capability to support BMDS-Element integration, missile defense wargames & exercises (national and international), BMDS training, and BMDS concept analysis. In this role, M&S provides cost-effective and proactive tools to assess the fielded capabilities of the BMDS, analyze and foster accelerated integration of Element and component capability into the BMDS, and is a valuable training and planning tool for warfighting Concept of Operations and missile defense planning. These M&S attributes enable the BMDS acquisition program to provide warfighting capability in a faster timetable and achieve tighter systems integration. Modeling and Simulation, anchored in ground and flight test program data, is a cornerstone for both developing the BMDS and gaining confidence in its performance, given that large amounts of flight data necessary to otherwise characterize the system is cost prohibitive. Likewise, M&S open architecture and frameworks are developed and implemented to reflect the open architecture characteristic of the Ballistic Missile Defense System. MDA objective 5.3 in the Strategic Intent states: Modeling and Simulation will acquire, develop, manage, direct, and execute high-fidelity models and simulations necessary for building and operating the BMDS. MDA will deemphasize stove-piped modeling efforts and invest in updating overall BMDS simulations and tools for use in ground-testing, wargames, and system level performance assessment. To accomplish this mission, M&S is organized into two product centers and two functional offices. The functional offices are Architecture and Engineering and Verification, Validation and Accreditation (VV&A). The product centers are BMDS Digital Modeling and Simulation, and BMDS Hardware-in-the-loop (HWIL). SIMULATION, ARCHITECTURE & REQUIREMENTS Architecture and Requirements (A&R) products include BMDS Event supporting system architectures and the standards and specifications used for BMDS model, simulation, and representation compliance. A&R provides Performance Assessment (PA) Scenario support for BMDS Test campaigns, implements a common Conceptual Model, and enables consistent/common Data Management and stakeholder collaboration. VERIFICATION, VALIDATION, AND ACCREDITATION (VV&A) Accredited system-level models and simulations (M&S) anchored to real-world events, are required to perform an accurate and comprehensive assessment of the BMDS. VV&A is responsible for implementing and documenting system-level M&S verification, validation, and accreditation which establish credibility and increases confidence in the M&S that provides a cornerstone for the Agency`s simulation-based acquisition approach. The individual MDA elements and components are responsible for conducting the VV&A of their own models and providing that evidence to system-level VV&A for each event. This includes benchmarking their M&S to higher fidelity simulations, anchoring to real world events, and planning and conducting post-flight reconstruction. VV&A annually verifies, validates and, accredits multiple MDA events to include Performance Assessment, Ground Tests that support BMDS fielding decisions, and tier one COCOM exercises. VV&A is responsible for the development and promulgation of system-level VV&A policies and standards, benchmarked against leading industry practices. VV&A provides model, simulation, and event credibility across Performance Assessment, Ground Tests, Element Integration, Wargames and Exercises, Training, and all associated infrastructure that supports BMDS fielding decisions. Through the consistent practice of verifying model representations benchmarked to other higher-fidelity models, and anchored to operational tests, VV&A will continue to increase model confidence and acceptability by outside agencies like the Operational Test Agency. Due to varying architectures and configurations required for different events, VV&A provides strong coordination, thorough analysis, development and use of appropriate tools, identification of metrics, and validation of both digital and hardware in the loop modeling and simulation capability. The implementation of the Model-Test-Model process requires that VV&A maintain close collaboration with the test community, and the capability to predict system-level test results and perform post-flight test reconstruction in order to improve model confidence and future performance. Robust VV&A requires flexibility and capability to explore new BMDS concepts, and evaluate new Element representations to identify and correct flaws early in the development process. BMDS DIGITAL MODELING AND SIMULATION BMDS Digital Modeling and Simulation produces and integrates digital M&S assets for use with the Digital Simulation Architecture to form system-level constructive simulations for full-envelope BMDS performance assessment with surrogate capability for BMDS ground tests. Digital M&S creates system-level stimulus for Element integration testing and system-level M&S capabilities which augment BMDS flight tests. Other mission areas include digital M&S capability for system-level concept definition and exploration; real-time, interactive system-level M&S capability to support warfighter-in-the-loop wargaming, training and exercises, and capabilities to support rapid, flexible scenario development and execution control. BMDS HARDWARE-IN-THE-LOOP (HWIL) BMDS HWIL Modeling and Simulation is responsible to provide and integrate the BMDS system-level HWIL stimulation framework to support full-envelope BMDS ground test, flight test, and training events based upon Agency and warfighter needs. BMDS HWIL provides development, integration, and test funding to both MDA and non-MDA Elements participating in the BMDS ground test campaigns. BMDS HWIL also provides the core Lethality and Phenomenology models for use in analysis of BMDS and Element mission requirements. BMDS HWIL additionally maintains the Advanced Research Center and Simulation Center High Performance Computing Capabilities to support test and M&S requirements across MDA.
