摘　　要：结构设计和优化方法关系到航电系统乃至战机可用性、扩展性和可维护性等多方面。分析系统结构设计过程,明确设计步骤,用于指导系统结构的构建。基于有向图理论,提出系统结构有向图的概念,并给出了数学描述。在此基础上,进一步阐述了结构优化算法,对系统结构有向图进行横向和纵向分解,建立了一种层次化的资源关联结构,为结构设计提供理论依据。最后,以实例说明了该方法的有效性。The structural design and optimization method is directly relevant to the avionic system as well as the survivability, expansibility and maintainability of the whole aircraft system. The design process is analyzed and the design steps are confirmed to construct system conveniently. A concept of the directed graph of system structure is proposed and the mathematical description is also presented based on directed graph theory. On this basis, an optimization method is further introduced. The structural directed graph of the system structure is decomposed vertically and horizontally, and a hierarchical association structure is set up for the system resources, which may supply a theoretical basis for structural design. Finally, an example demonstrates the effectiveness of the proposed method.
