title = "Information fusion for national airspace system prognostics: A NASA ULI project",
abstract = "Expanding Prognostics and Health Management (PHM) from an equipment-centric view to complex large-scale engineering systems is a challenging problem. One example for a large engineering system is the next generation national airspace system (NAS), which is a fully coupled cyber-physical-human system. This paper presents an overview of a NASA University Leadership Initiative (ULI) project which aims to address the safety needs and their technology solutions for future NAS. The ULI is a 5-year collaborative project in which researchers from several universities and commercial entities work together to advance real-time airspace safety concepts. The underlying premise is that it is imperative to be able to assess and predict the evolution of the airspace's safety state. Towards that end the work envisions to address the following issues: modeling of the airspace using both data-driven and physics-based approaches; quantifying and managing uncertainty; advancing prognostics and information fusion algorithms; and understanding and modeling human computer interface. A comprehensive simulation environment is being built that allows for assessment of performance and verification and validation. The paper discusses the various activities and places them into the context of overall NAS safety.",

note = "Funding Information: ULI is a project initiative that was meant to engage Aeronautics Research Mission Directorate (ARMD) and the academic community in a new type of interaction where universities take the lead, build their own teams, and set their own research path. ULI seeks new, innovative ideas from university-led teams to support the NASA ARMD research portfolio and the U.S. aviation community. To that end, university teams are being challenged to address unique research questions associated with ARMD strategic thrusts (NASA 2017), defining interdisciplinary solutions, establishing peer review mechanisms, and applying innovative teaming strategies to strengthen their research impact. In order to transition their research, the projects have been challenged to actively explore transition opportunities and pursue follow-on funding from stakeholders and industrial partners during the course of their award. This paper describes the efforts that are being undertaken for the ULI project awarded under the strategic thrust Real-Time System-Wide Safety Assurance.
