METHOD AND DEVICE FOR PERFORMING A MAINTENANCE FUNCTION
First Claim
1. A method for performance of a maintenance function of a system under diagnosis, the system comprising a plurality of processing units using a description of the system under diagnosis, the description comprising a description of the processing and memory resources of the various processing units, said method comprising:
- a step for determination of sub-systems based on the description by carrying out a hierarchical decomposition, the system being decomposed into various hierarchical levels into which the various processing units are grouped, a first hierarchical level being said to be lower than a second level when the first level comprises processing units composing processing units of the second level, the various processing units being identified as sub-systems;
for each sub-system, steps for;
determination of a behavioral model of the sub-system with a model editor enabling the behavioral model to be generated starting from the description of the system; and
allocation of a diagnostic method depending on the processing and memory resources of said sub-system; and
transfer of a diagnostic function to the sub-system depending on the diagnostic method allocated.

Abstract
A method for performing a maintenance function of a system under diagnosis includes a step for hierarchical decomposition of the system under diagnosis into sub-systems based on the model of the system and, for each sub-system, steps for determination of a model of the sub-system starting from the model of the system, and allocation of a diagnostic method depending on the processing and memory resources of said sub-system. The method allocated is a first diagnostic method based on the model of the system or a second diagnostic method based on predefined logical relationships. The method further includes calculation of the logical relationships for the sub-systems implementing the second diagnostic method, and the transfer of the logical relationships to the sub-systems implementing the second method and the transfer of the model to the sub-systems implementing the first method.
