- Abstract:
-
Flexible logic is proposed in this paper to describe and transform the space fault network (SFN) and to describe the system fault evolution process (SFEP) with information uncertainty and evolution characteristics to overcome the factors, data, and evolution uncertainty. The present report discusses the problems of SFN and the possibility of using flexible logic to solve these problems. The use of flexible logic to describe SFN should be based on the basic unit, event occurrence relationship, and SFN structure. Flexible logical representations of the and, or and transfer relationship in SFN are given. Further, under the condition of flexible logic, the relationship set of SFN is given, and the flexible logic representation of the target event state of SFN is obtained. The results show the flexible logical relationship and uncertainty among events, factors, and evolution processes in SFEP and provide a new methodology and theoretical basis for the intelligent research of SFEP.
