Abstract: Aiming at the problem of various equipment and complicated correlations in operation system-of-systems under the information conditions, an evaluation method of equipment’s contribution rate to system-of-systems based on operation loop and self-information quantity is proposed from the perspective of system-of-systems effectiveness. The equipment and correlations are abstracted as nodes and edges. The edges’ metrics are determined according to the tactical and technical indexes of the nodes, and the network model of operation system-of-systems based on operation loop is constructed. According to the number and effectiveness of the operation loop involved in each target node, the method for evaluating the effectiveness of operation system-of-systems based on self-information quantity is proposed. And the corresponding evaluation model is built. Taking an anti-aircraft carrier operation system-of-systems as an example, the results show that the proposed method has fully taken the heterogeneity and uncertainty of each equipment and correlation into consideration to evaluate the equipment’s contribution rate to system-of-systems comprehensively and objectively. The proposed method can provide methodological support for equipment demonstration and operation system-of-systems optimization.
