Advanced MBSE techniques are equally applicable to trade studies on defense system variants. In this study, alternate equipment packages for an infantry soldier, and the analysis models for cost mobility and other metrics were incorporated in a single SysML model, shown in the MagicDraw block definition diagram in the first figure below. The analysis models were realized in SysML parametrics and evaluated using ParaMagic (Intercax) for a series of alternate body armor configurations realized as instances of the model.

Integrated modeling of defense and intelligence systems

Intercax has developed a Model-Based Engineering platform Syndeia to address this. A high-level architectural model for a configurable UAV is created in SysML (IBM Rational Rhapsody in this example), as shown in the first figure above. The individual elements are linked to subsystem models in PLM, CAD, ALM and simulation tools and further connected to requirements and project management information. The second figure is a visualization of the connection database for a specific UAV configuration, linking the SysML model elements to corresponding model elements in Teamcenter (PLM), GitHub (ALM), Simulink (simulation) and JIRA (project management). These connections allow on-going information comparison and transfer between tools to create a Total System Model that can be evaluated and ultimately assembled and tested in a shorter time. Properly-managed connections can not only share information; they can restrict what parts of the models are shared to protect confidential or proprietary data.
