System of Systems complexity and decision making

Complexity in System of Systems (SoS) is a key factor in SoS decision making. This paper analyzes the main characteristics of SoS, especially its complexity in terms of monolithic emergence, component systems adaption and uncertainty in SoS evolution. It further discusses the effects of SoS complexity on SoS decision making. In light of SoS complexity, the paper figures out the major problems that need to be addressed in four areas, namely SoS adaption, abnormity analysis in SoS evolution, exploratory analysis of SoS capability and SoS simulation. In conclusion the paper proposes a preliminary SoS decision making model based on the analysis of SoS adaption.
