Resource Modeling and Capability Assessment for Space-Based Information System

For the space-based information system with a large scale, a wide variety of nodes, complex connection relationships and dynamic structural changes, a multi-level system resource model is firstly established and a combined qualitative and quantitative assessment index system based on expert knowledge is proposed. Finally, a space-based information system capability assessment method is established by combining hierarchical analysis methods, and the results of calculation examples show the correctness and reasonableness of the method.
