The foundation for the ERS program consists of the following key areas for investment
- This sub-area capabilities are focused on enabling deeper consideration of system design alternatives, while keeping the design options open as long as possible to address resiliency to changing conditions and constraints. The tradespace analysis capabilities support highly complex decision-making across the lifecycle by communicating to multiple perspectives across the system hierarchy, while considering fiscal and environmental constraints. The tradespace analysis tools analyze the complex resources, costs, and technical considerations in system requirements for ships, aircrafts, ground vehicles, etc., and design alternatives.
The goal of ERS is to become a DoD-wide framework that provides a standardized approach to analyzing new systems or adapting existing systems to changing mission requirements. ERS will accomplish this by developing and integrating a suite of products that will provide a magnitude of improvements to the existing acquisition process. This sub-area will develop approaches for knowledge sharing, management, and representation to support complex distributed engagements between scientists and engineers working on feasibility assessment of conceptual designs; integrated product teams representing all functional disciplines; program managers to broaden the tradespace beyond performance; test and evaluation teams to support the planning and execution of T&E by focusing on key designs to validate developmental and operational testing; program executive officers to focus on delivery, cost, and risk integration; and industry to refine designs, approaches to knowledge sharing, management, and representation to support cross-cutting decision processes.
This sub-area is focused on identifying, evaluating, and assimilating new and existing modeling and simulation tools for evaluating the performance of proposed materiel solutions in a wide range of environmental conditions. This sub-area will make use of high-fidelity modeling capabilities that exist across the DoD to model future systems early in the acquisition process. Models and simulations require a wide range of environmental data to assess the impact of the environment on future weapons systems. This sub-area will identify gaps in the existing datasets and invest in environmental models to fill those gaps as needed, specifically including: physics-based representations of systems; manufacturability and producibility analysis; mission context representations; and systems of systems representations.
One of the primary ERS goals is to develop an architectural framework that enables the integration of disparate systems and systems-of-systems for the purpose of performing analyses throughout the systems life-cycle. The framework will maintain a level of openness while accommodating pertinent data, analysis tools, collaboration, and multiple tool types. This sub-area will identify DoD platforms that can benefit from the ERS approach, as well as create an active user community to transfer lessons learned that will benefit future ERS development efforts. ERS will identify, evaluate, and select from relevant models what is needed to create robust, integrated, computational prototyping environments to be used by the Services and OSD.
In addition, ERS strategically leverages and greatly augments the tool development efforts and processes of the Computational Research Engineering Acquisition Tools and Environment (CREATE) component of the DoD High Performance Computing Modernization Program. CREATE tools are focused on innovative software development and capability transition for the acquisition and engineering communities.
The CREATE's software development efforts and their capability objectives that are integral to the ERS Program are as follows:
- Helios: facilitates full rotorcraft (all types, manned and unmanned) high-fidelity simulation
- Kestrel: performs computational fluid dynamic, structures, kinematics, and kinetics as well as other analyses
- Capstone: provides a comprehensive and integrated set of geometry, meshing, and associative attribution software capabilities.
- NavyFoam: provides the ship design engineer with the capability to rigorously analyze alternative hull form designs
- IHDE (Integrated Hydrodynamics Design Environment): provides the prediction of the hydrodynamic performance of a ship design
- RSDE (Rapid Ship Design Environment): provides a high-end toolset that integrates ship design generation tools with physics-based analysis
- NESM (Navy Enhanced Sierra Mechanics): predicts ship structural response and damage due to loading for stand-off and close-in air, surface, and underwater explosions
- SENTRi (computational electromagnetics): provides finite element / boundary integral code for radiation and scattering analysis
- CREATE-GV: provides a suite of software for analyzing ground vehicles
