摘要:

建设与发展有效的装备体系需要依赖合理的效能评估方法。诸多评估方法在复杂依赖关系的量化分析上存在不足, 因此引入功能依赖网络分析(functional dependency network analysis, FDNA)法, 通过双依赖参数、分段线性模型等捕捉体系复杂依赖关系及其造成的级联效应。进而立足FDNA方法的优点, 突破其局限性, 提出基于作战环的功能依赖网络建模规范, 通过链路健康指数、综合依赖关键度、多系统冗余表决系统等调整、新增、完善效能聚合模型, 形成可捕捉和反映更广泛作战场景的扩展FDNA(extended FDNA, E-FDNA)方法。以海上防空反导体系为例, 通过与现有FDNA系列方法以及复杂网络方法在体系效能值、关键系统识别等方面的对比分析, 验证了E-FDNA方法的可行性和有效性, 为装备体系的效能评估提供了新方法。

Abstract:

Developing effective combat system-of-systems (SoS) requires appropriate effectiveness evaluation methods. However, most current evaluation methods are short of capturing the complex interdependencies. This paper thus brings in a functional dependency network analysis (FDNA) method that is able to depict the interdependency relationship and its cascading effects within an SoS, using two interdependency parameters and a piece-wise linear model. This paper keeps the advantages of FDNA while overcoming some of the shortfalls. Particularly, this paper proposes operation loop based modeling rules for building functional dependency network of combat SoSs. Meanwhile, this paper adjusts and completes the effectiveness aggregation model through adding interdependency health index, synthetic criticality of dependency, and multi-systems redundancy voting system. This new extended FDNA (E-FDNA) method is able to reflect the SoS effectiveness under more combat scenarios. In the end, the E-FDNA method is applied to a naval air and missile SoS. The comparison with current FDNA related methods and complex network theory method, regarding the effectiveness value and critical system identification respectively, demonstrates the feasibility and effectiveness of the E-FDNA method. Hence the proposed E-FDNA method offers a new method for SoS effectiveness evaluation.

Key words: combat system-of-systems (SoS), effectiveness evaluation, functional dependency network analysis (FDNA)
