Abstract

System-of-systems (SoS) architecting is an important and difficult problem. Modeling and optimization are practically essential to develop a quality solution. However, modeling and optimization are highly specialized fields in their own rights and can easily become an obstacle to the architecting effort. SoS Explorer is a tool designed to mitigate this difficulty by providing a structured, yet flexible approach. Moreover, SoS explorer provides interactive visualization as well as a number of optimizers. Interactive visualization allows the architect to perform “what-if” analysis while the optimizers provide solutions that can act as initial architectures and demonstrate the optimal trade-space. The utility of this approach is demonstrated with a notional 22-system toy problem.

Appendix A. Python Source Code

The full Python code used in the ISR example for the “Performance” objective is listed below. Due to space constraints, the other objectives are not listed but follow similarly from their definitions. The code in lines 1–85 was automatically generated by SoS Explorer requiring only lines 86–103 (implementing Eq. 14.1) to be written by the user.
