Evaluation of system-of-systems using two layer fuzzy analytic network process model

The evaluation of system-of-systems is a very important content in the research of system-of-systems (SoS). An evaluation approach of system-of-systems using a two layer model based on fuzzy analytic network process is proposed in the paper. A two layer network, mission network and capabilities and systems network, is introduced to represent the complex interconnections and interactions in SoS under uncertain context. Experts´ knowledge on SoS evaluation is extracted by a series of questions. Algorithm for deriving priorities from the model is proposed. Finally, the numerical example of air defense system-of-systems evaluation demonstrates the application of the proposed approach.
