摘要
The invention concerns a method for highlighting failures capable of triggering problems in the operating conditions of a system, which consists in collecting N failures Pi representing the status of the system including at least the following steps: determining the influence of a failure Pi on another failure Pj, using a database representing the history of failures and statistical tools for calculating the number of times when a given failure has preceded another failure; creating a ''clipped'' matrix G having as general expression: formula (I); transforming the ''clipped'' matrix G into a symmetrical matrix; determining by a classifying engine classes of failures which have mutual relationships; creating an oriented graph, expressing the relationships of influence existing among the classes obtained at the previous step, comparing the data representing a status of the system at a given time with the oriented graph and with the classes of failures having mutual relationships, and outputting a signal representing the result of the comparison.
