Method for detecting faulty equipment

Abstract

One aspect of the invention relates to a method (100) for detecting a faulty piece of equipment among a plurality of equipment in a device from a dynamic global decision tree.The detection method (100) comprises: at a current node of the global decision tree, displaying (110) the question relating to a device failure respectively associated with the current node; in response to the display (110) of the question, receiving (120) information relating to a characteristic of at least one piece of equipment from among the plurality of equipment; determining (130) at least one piece of equipment to be checked from among the plurality of equipment in the device based on the information received; selecting (140) at least one decision tree from among the decision tree(s) associated respectively with the at least one piece of equipment to be checked; and updating (150) the global decision tree by replacing a lower branch of the current node with at least a portion of the selected decision tree. Figure to be published with the abstract: Figure 1.

Claims

- Completed with failure to detect faulty equipment, in which the selection (140) of at least one decision tree is made by excluding decision trees comprising nodes associated with the status indication "Completed with failure to detect faulty equipment", or in which at least a portion of the at least one selected decision tree is determined by excluding nodes associated with the status indication "Completed with failure to detect faulty equipment".

8. Detection method (100) according to any one of the preceding claims wherein the updated global decision tree (160) is displayed.

9. Product computer program comprising instructions which, when the program is executed by a computer, cause the computer to carry out the method according to any one of the preceding claims.

10. A system for detecting faulty equipment comprising means adapted to carry out the detection method (100) according to any one of claims 1 to 8.
