Applying model-based systems engineering to architecture optimization and selection during system acquisition
The architecture selection process early in a major system acquisition is a critical step in determining the overall affordability and technical performance success of a program. There are recognized deficiencies that frequently occur in this step such as poor transparency into the final selection …

Tradespace exploration for space system architectures : a weighted graph framework
Many systems undergo significant architecture-level change during their lifecycles as a result of exogenous system disturbances (e.g. budget reduction or changes in stakeholder requirements), failure to develop critical technologies, or planned evolution of the system over time. Given the high cost …
