Summary: | The principles and methods of Model Driven
Architecture are applied to the problem of requirements
traceability for a System of Systems (SoS). Model
transformations of operational threads are used to reduce
the complexity of modeling mission requirements and their
flow into the architecture of the SoS. The allocation of
requirements to operational mission threads (OMTs)
rather than to individual systems reduces the complexity of
the requirements tracing. Relational transformations
provide a mathematically based formalism for model
transformations that permit precise computation of the
transformation of operational threads into threads of
systems allocated from the SoS. Connectivity requirements
for the SoS are also exposed in this way and the number of
permissible system threads are seen to correspond directly
to the number of permissible transformations. The
principles and methods are illustrated by an elementary
case study for sensor fusion. |
