SBIR/STTR Award attributes
Key elements of NASArsquo;s Digital Transformation initiative strategy calls for ldquo;digitally transforming NASArsquo;s data use, collaboration, model-based work, administrative processes, application of artificial intelligence, and workforce and culturerdquo; and this SBIR proposal is specifically addressing the model-based work area.nbsp;Mosaic proposes to develop a Digital Engineering Information Exchange Model (DEIXM) based on open-source standards including SysML, UML and ISOrsquo;s STEP ndash; standards for the exchange of product model data ndash; group of standards along with a DEIXM Model Viewer (DMV) that provides a centralized location to view digital model artifacts in a common format.nbsp;Ultimately, the DMV along with the DEIXM will demonstrate the integration of digital models developed in different MBSE tools that maintains model integrity with minimal need to manually edit the digital models.nbsp;The idea of creating a standards-based approach to sharing digital model data between organizations was presented by the Department of Defense in a 2018 briefing for the 21st Annual National Defense Industrial Association Systems and Mission Engineering Conference.nbsp;The briefing called for the creation of a DEIXM that would facilitate the exchange of textual, graphical, tabular, and other digital model artifacts along with an ldquo;integrated digital viewer.rdquo;nbsp; Implementing a DEIXM is envisioned to reduce the amount of effort required to integrate digital models between the government and contractors, as well as between contractors.nbsp;The DEIXM created in this effort will focus on establishing a standard that supports NASA missions.nbsp;It will leverage previous efforts to use MBSE to support space mission design from the NASA MBSE Pathfinder work done across NASA, as well as lessons learned from the DEIXM Working Groupnbsp;established by the OMG.
