【摘要】 为获取功能依赖网络分析(functional dependency network analysis,FDNA)依赖强度参数α和依赖关键度参数β,提出一种基于邻接矩阵和可达矩阵的求解功能依赖网络中依赖强度和依赖关键度参数方法。在Petri网出现图的基础上,给出定量求解依赖强度和依赖关键度参数的公式,并通过体系效能依赖强度和依赖关键度的求解实例和体系效能敏感性分析进行验证评估。结果表明:该方法是合理、可行的,能弥补当前FDNA应用研究中的不足。更多还原

【Abstract】 In order to acquire the functional dependency network analysis(FDNA) strength of dependency(SOD) parameter α and criticality of dependency(COD) parameter β, this paper proposed a method to analyze the SOD and COD parameters through adjacency matrix and reachability matrix. Based on the occurrence graph in Petri net, proposed formulas to calculate SOD and COD parameters, and the results are validated by the solving examples of the system of systems effectiveness SOD and COD parameters and its sensitivity analysis. The results show that the method is reasonable and feasible, which can make up the deficiency of the current FDNA application research.更多还原
