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.
