FDNA of SoS Effectiveness

For acquiring dependency strength α parameterand dependency criticality β parameter of functional development dependency network analysis (FDNA), use system of systems (SoS) model simulation to realize evaluation method of parameterαkj andβkj. By analyzing FDNA effectiveness calculation formula and system effectiveness analysis simulation evaluation, taking low orbit monitoring satellite robustness analysis as example, acquire dependency parameter of FDNA formula by curve, then carry out system robustness analysis for FDNA model. The results show that the method is convenient and practical, and it can provide reference for related research.
