Abstract:

Functional dependency is one of the important factors influencing the performance of large-scale complex systems or the generation of system of systems (SoS) capabilities. The expression, identification and measurement of functional dependency among various element entities are important issues in the study of complex SoS. Through the analysis of the dependence of the interaction behaviors between the element systems in the networked information system of systems (NISoS), the dependency network model of NISoS (DNMN) is constructed based on the function dependency network (FDN). By consider the combat attributes and mission completion effects, the node importance measurement index is proposed, and on this basis, a FDNA-based gravity center evaluation (GCE) method of NISoS is given. Finally, the validity of the DNMN model and GCE method are illustrated by a case of maritime joint operation NISoS.

Key words: function dependency network (FDN), networked information system of systems (NISoS), system of center of gravity, network model, metrics indicators
