Abstract
We present the work on applying Model-Based Systems Engineering (MBSE) to the conceptual design of the MANIFEST multi-object fiber positioner for the Giant Magellan Telescope (GMT). We use MBSE early in the system lifecycle to help identify and document the MANIFEST system characteristics. The application of MBSE allows the discovery of potential problems and their solutions. In addition, the MBSE facilitates managing complexity, reducing technical risk, and performing risk analyses. First, we report the benefits of the modeling process in capturing the problem domain model and stakeholder needs. Then, present the model framework, systems modeling language, and software tool to accomplish our goals for MANIFEST. Next, we report on the MANIFEST architectural products, the structural and functional elements, associated mappings, and relationships, including the interfaces between subsystems and external systems. Then we discuss the model presentation and report generation to communicate design aspects to stakeholders. Finally, we conclude with remarks about the effectiveness of the MBSE approach for the MANIFEST conceptual design.
