Execution of systems integration principles during systems engineering design

MetadataShow full item record
Systems integration (SI) is an extensive task conducted as part of the bottoms-up systems engineering (SE) lifecycle approach. Implementation of a newly developed system depends on successful accomplishment of systems integration. Complexities of system design solutions are making SI success more difficult to achieve; integration failures have become more common and tend to drive costly redesign efforts. This research explores some of the integration failures and causes and proposes SE developmental phase considerations regarding requirements, stakeholders, testing, and system boundaries. Additionally, this thesis discusses use of systems architecture frameworks and models and the consistent use of model-based systems engineering throughout development. Lastly, it proposes formal methods language for improving models. This research describes how all of these solutions can facilitate identifying and resolving common SI failures prior to the completion of system development. By doing so, the success of the integration effort and the system as a whole is ensured.
