- Abstract
- This paper investigates farther the decomposition of diagnosis problem. Firstly, the relationship of test, component and signal attribute is described, the fault space of system is separated by the free-fault space, which can prune the diagnosis space, and minimal diagnosis was characterized by using function information. Secondly, this paper presents an algorithm for computing minimal diagnosis by using function information and an idea for partitioning the system by using function information. Finally, the correctness and completeness of the algorithm is proved, and the time complexity of the algorithm is also analyzed, which farther improves the effectiveness of diagnosing the systems and extends adaptability of decomposition of diagnosis problem.
