Abstract
The invention relates to a method for aiding the maintenance of a system, the system comprising a set of networked elements, the system being accompanied by indications defining subsets of networked elements Ei, each subset of networked elements Ei being associated with a probability of failure Pi, the including the steps of calculating a first value Ti for each subset of networked elements Ei, the first value Ti including an estimation of the maintenance time related to the repair of the subset of networked elements Ei, calculating a second value Fi for each subset of networked elements Ei, the second value Fi including a representation of a compromise between the estimation of the maintenance time Ti related to the repair of the subset of networked elements Ei and the probability of failure Pi of the subsets of networked elements Ei, and sorting the designated sets of items of equipment Ei in order of decreasing second value Fi.
