MBSE models the requirements, structure, performance, and behavior of systems (or SoS). Mission Analysis is about effectiveness and emergent behavior. SysML is temporally and spatially oblivious. While it can be used to conduct engagement-level analysis (i.e. performance of a SoS) it cannot evaluate effectiveness. The relationship between the MT/MET and the scenario is homeopathic, at best. To evaluate effectiveness you need a mission-level simulation. In the mission-level analysis we compare various architectures to identify the most cost-effective system. The system that contributes to the most cost-effective SoS determines the system level requirements. Mission level and system level are co-dependent. Effectiveness is the measure that matters. Performance is what you pay for. Every requirement needs to earn its way into the system.

thank you for sharing. it really helps. and I'm wondering if the ppt and model are available? thanks again.
