摘要:

为了深入分析装备体系内各装备系统在任务执行过程中自身性能退化对其相互依赖性的影响, 并准确把握体系内各装备系统在自身性能退化和相互依赖性的双重影响下其当前效能的演变规律, 对传统功能依赖网络分析(functional dependency network analysis, FDNA)方法进行了一定改进。引入自身效能退化系数, 给出考虑时间因素的动态FDNA算法; 以Markov过程为基础, 构建体系内装备系统的性能退化模型, 为自身效能退化系数的计算提供相应依据, 从而提出一种基于功能依赖网络的装备体系任务能力依赖性分析方法, 并用案例验证了方法的可行性。

Abstract:

In order to deeply analyze the influence of the performance degradation of each equipment system in system of systems on interdependency among them and accurately grasp the evolution law of the current efficiency of each equipment system under the dual influence of its own performance degradation and interdependence. The traditional functional dependency network analysis (FDNA) method is improved and the self-effectiveness degradation coefficient is introduced to give a dynamic FDNA algorithm considering time factor. And the performance degradation model of the equipment system in system of systems is constructed based on the Markov process to provide the corresponding basis for the calculation of self-effectiveness degradation coefficient. Then, a task capability dependency analysis method of weapon system of systems based on the functional dependency network is proposed, and the feasibility of the method is verified by a case.

Key words: weapon system of system, performance degradation, functional dependency network analysis (FDNA), Markov process, dependency analysis
