Optimizing Aircraft Fault Isolation Methods Based on Gray Relation Vague Clustreing Algorithm

To limit of the on-the-spot condition, the aircraft fault isolation expert system gives neither the exact fault reason, nor the direction of selecting the isolation methods. To solve this problem, this paper sets up a gray relation vague clustering algorithm based on gray relation analysis and fuzzy clustering principle. This algorithm is adopted to sort all fault isolation methods corresponding to the probability of the fault isolation. Then it has the similar clustering for the result of the order. The algorithm brings about the solution of the key problem of optimizing fault isolation methods, and gives the direction of selecting the isolation methods directly by synthesizing the fault isolation experience and the algorithm of many elements decision effectively. It improves the direction depth and the aircraft fault isolation efficiency. Finally the theory of the algorithm is presented and the actual example for application is given.
