Aiming at the new characteristics of system value in weapon system-of-systems, a comprehensive analysis method of system network value based on network model is proposed. The system value analysis framework of weapon system-of-systems is constructed. The system value synthesis method is obtained by quantitatively describing the network cluster coefficient through the multi-level fuzzy comprehensive evaluation method, combining the individual value of the system with the network value analysis method. The analysis results show that this method can solve the problem of system value analysis in the process of the construction of weapon system-of-systems and is a method that can comprehensively consider system value analysis.
