Abstract: Method for determining a reliability state of an electrical network, the electrical network comprising a plurality of interconnected electrical devices, the method including the following steps: a) identifying an undesired event at a given location in the electrical network; b) traversing at least one subset starting from the given location; c) identifying an electrical device of the electrical network; d) determining a list of events of concern that are associated with the identified electrical device and could result in the undesired event; e) determining a total unavailability value associated with the identified electrical device; f) repeating steps b) to e); and g) calculating a reliability state of the electrical network on the basis of the total unavailability values respectively associated with the traversed electrical devices.
