空间故障网络及其与空间故障树的转换

空间故障树是一种研究系统可靠性与影响因素关系的理论体系，用树型结构描述元件与系统之间的可靠性关系。但实际故障发生过程是复杂的，难以表示成树型结构，而更为广泛的是网状结构。因此，尝试将空间故障树中的树型结构转换为网络结构，进而形成空间故障网络。给出空间故障网络的定义、性质及其与空间故障树的转换方法。目的是将空间故障网络转换为空间故障树，以利用空间故障树已有研究结果。给出一般结构和多向环结构的空间故障网络，及其转换为空间故障树的方法。为使用空间故障树理论研究一般网络结构故障发生过程提供方法。

Construction space fault network and recognition network structure characteristic

The space fault tree is a theoretical system to study the relationship between the system reliability and influencing factors. The tree structure is used to describe the relationship. But the actual fault process is complicated, it is difficult to represent the tree structure, and the more general is the network structure. Therefore, this paper attempted to transform the tree structure in the space fault tree into a network structure, and then form a space fault network. The definition and properties of the space fault network and the transformation method with the space fault tree are given. The purpose is to transform the space fault network into space fault tree, and to make use of the existing research results of the space fault tree. The space fault network has the general structure and the multi direction ring structure, and the transforming method into a space fault tree is given. In order to use the space fault tree, a method for the fault process of general network structure is provided.
