By leveraging the existing Model‐Based Systems Engineering (MBSE) infrastructure at JPL and adding a modest investment, the Europa Mission Concept Study made striking advances in mission concept capture and analysis. This effort has reaffirmed the importance of architecting and successfully harnessed the synergistic relationship of system modeling to mission architecting. It clearly demonstrated that MBSE can provide greater agility than traditional systems engineering methods. This paper will describe the successful application of MBSE in the dynamic environment of early mission formulation, the significant results produced and lessons learned in the process.
Abstract. In May 2012 the Europa study team delivered to NASA the final reports on three distinct concepts for exploring Europa on a limited budget. The depth and quality of these reports have been widely praised by independent reviewers as well as by our sponsor. The application of Model Based Systems Engineering (MBSE) techniques is credited with enabling the team to study three quite different mission concepts for the resources normally sufficient to study only one or two. The Europa MBSE infusion itself has been awarded the NASA Systems Engineering Excellence Award in 2012. The Europa team is now preparing for its Mission Concept Review and has reaffirmed and strengthened the MBSE application. Significant new capabilities have been completed, most importantly the Powered Equipment List (PEL) and the computation of scenario-based power and energy margins. This paper provides an update on the continued successful application of MBSE in the dynamic environment of early mission formulation, the significant new results produced and several additional lessons learned in the process.
As JPL's missions grow more complex, the need for improved systems engineering processes is becoming clear. Of significant promise in this regard is the move toward a more integrated and model-centric approach to mission conception, design, implementation and operations. The Integrated Model-Centric Engineering (IMCE) Initiative, now underway at JPL, seeks to lay the groundwork for these improvements. This paper will report progress on three fronts: articulating JPL's need for IMCE; characterizing the enterprise into which IMCE capabilities will be deployed; and constructing an operations concept for a flight project development in an integrated modelcentric environment. 1 2
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
