A model framework for determining dynamic architecture goals in a systems-of-systems

Abstract

This paper presents results from a prototype modeling methodology, part of a PhD project intending to create an integrated model framework relating societal modeling techniques to system-of-systems (SoS) architecture models and design. This framework uses matrix-based and system dynamics (SD) models to relate product system functions to associated systems and to societal dynamics stepby- step, in order to synthesize justified design priorities for a new product platform. In this manner, function importance weights or goal prioritization for a new product are obtained from societal models and scenarios. These weights are highly dependent on outside (SoS) functions, vary in time, and depend on the risk attitude of the project. In future work, this framework will be applied to modularization and architecture design and evaluated by a case study in the aerospace industry, where a space system manufacturer is considering designing new satellite product lines.
