Objective: To develop better methods of conducting system trades involving aspects of the system that are difficult to quantify, such as resilience and safety, and the cost, schedule and performance impacts of such trades
Approach: The project will be a multi-year research effort conducted in several phases. The first phase (RT 46) consisted of a number of separate activities, including
- Developing an understanding of the different DoD stakeholder priorities for the ilities
- Development of frameworks for understanding and making trades against such factors, and
- Creating an initial demonstration capability, ideally leveraging, as much as practicable, existing research and commercial tradespace tools.
The focus of the second phase (RT 46) and third phase (RT 113) is to apply the methods and tools developed in the first phase on problems relevant to DoD, ideally using the information available from development of a large weapon system, or a large automated information system. Ideally, the SERC will work with the system developer to gain a deep understanding of the strengths and limitations of the tradespace tools methods developed under Phase 1. Phase 2 and 3 activities will expand the set of ilities represented in the tradespace. The information learned from Phases 2 and 3 will be used to improve the frameworks and tools developed in the Phase 1 activities.
