Increasing the productivity of an MBSE development team throughout the system design lifecycle

摘要

Increasing the productivity of a Model Based Systems Engineering (MBSE) development team and improving first time quality of its end product requires maintaining coordination and synchronization of the information needed between multi-discipline environments. Developing complex systems is not the sole province of a single tool or flow. This calls for a real time digital thread built upon industry standards and providing a linkage between the tools used in that environment; a linkage that reflects the work flow and provides this necessary information in a way that is easily and intuitively accessible to each member of the engineering team as they work. In this paper, we discuss an innovative solution to this problem based on the capture and implementation of work flow metamodels, linking current tools and working within an existing set of activities or flows, such as to enable linked sharing of relevant information between all participants. The Open Services for Lifecycle Collaboration (OSLC) [1] standard provides an enabling technology, extended by a configurable metamodel-based approach to incorporate a central organizing structure for data tracking, history and analysis that spans all the domains and stages from concept, requirement, functional and logical design through implementation and test. Additionally, the metamodel extends upon the standard domain capabilities by augmenting each connected tool with communication, GUI and data access that enables direct participation in the lifecycle without the discontinuities and losses usually experienced with separate tools and flows.
