The automated integration of descriptive models and analytical models has been sought by the systems engineering community to manage the effects of requirements change to reduce defects, cost, and schedule. The Executable Model Integration Bridge (EMIB) demonstrates that objective through the integration of requirements in IBM Rational DOORS® traced to architectures in Atego Artisan Studio® with design parameters that affect cost values in cost tools built in Microsoft Excel®, and performance analyses in MATLAB® models via a central automation and integration tool (Phoenix Integration ModelCenter®). Through EMIB, we can analyze the impact of changes to constraint requirements by developing descriptive models in Systems Modeling Language (SysML) with links to the system performance requirements. The descriptive model contains behavioral views that capture the flow of system and actor behavior required to satisfy the requirements, structural views to depict the elements of the system as blocks with current design and constraint values, and parametric views to capture the relationships between system element blocks and constraint elements. This integrated approach allows us to ingest the design values from an analytical tool (MATLAB®) into a descriptive tool (Atego Artisan Studio®) to provide early validation that the input (given) and output (target) design values are within the allowed ranges imposed by the constraint values (i.e. requirements). To demonstrate this functionality, a simple, top-level radar model was contrived and implemented whereby cost and performance results associated with material choices can be evaluated against customer specifications for emplacement/displacement times, weight, power, cost, and antenna performance in the descriptive model. An interactive model to achieve the aforementioned objectives was realized. This integration process and potential benefits of this approach will be explored in this presentation.
