Research on analysis method of event importance and fault model in space fault network

To study the event importance and their role in the system fault evolution process (SFEP), and the possibility of fault mode, the analysis methods of event importance and possibility of fault mode are proposed. This paper is the series of research in related fields including four methods. The event importance in fault process to fault evolution is studied from fault mode. Change to Field theory is used to study the relationships between events in the fault process to judge the event importance. For the structure of space fault network (SFN), the possibility of fault mode is studied. Based on some events have occurred, the potential possibility of fault mode is studied. At the same time, some examples are given to illustrate the use and processes of these methods. These methods can study the event importance and the characteristics of fault occurrence in SFEP within the framework of SFN. The methods are suitable for computer information storage and data processing, and are suitable for intelligent analysis and data processing of SFEP, and enrich the theory of SFN
