One of the foremost challenges in large system design is keeping the engineering effort scalable. This is typically where engineering software becomes invaluable. As such, the question becomes, "How scalable is the software you are using?"DSI has always recognized this problem as one of the principle design goals of the eXpress software. It is fairly easy to identify some key areas in which the system size becomes a concern:
- Introducing additional lower-level data
- Changing connectivity (model structure)
- Changing testing and diagnostic approaches
- Validating designs against the specification or other models
Solving the scalability problems associated with each of these provides the ability to run assessment reports so that optimization can occur.
