1. Method for the automated management of a plurality of services envisaged by a predetermined communications plan of a telecommunication system on-board a naval unit comprising a plurality of radiocommunication apparatus, the method comprising: defining static constraints or criteria during a planning stage, representative of the apparatus forming part of the on-board system, including a respective first set of data indicating the nominal operating parameters of said apparatus and a respective second set of data indicating the predefined assignment of said apparatus to predetermined services; defining dynamic constraints or criteria during a planning stage, representative of the current operating state of said apparatus, including a respective first set of data indicating the state of use of the apparatus by active services and a respective second set of data indicating the operating condition of the apparatus; acquiring a request for activation of a service; searching for a communications resource including a combination of apparatus, adapted to perform the service required on the basis of said static constraints associated with the selected apparatus; checking for availability of the resource, on the basis of said dynamic constraints associated with the selected apparatus; then: if the resource is available, assigning said resource to the service required; if the resource is not available, assigning a different resource including a different combination of apparatus available for the service required, selected on the basis of said static constraints or criteria and said dynamic constraints or criteria, wherein the assignment of the resources available on the basis of said static and dynamic constraints to the services required is performed in accordance with a priority criterion associated with the services by an operator during the planning stage, and in the event of there being no free resources, resolving conflicts relating to the assignment of resources in accordance with a predetermined criterion, including checking existence of a different resource currently used by another service and, where the currently active service has a lower priority than the service required, suggesting to a human operator assignment of the occupied resource to the service with a higher priority and deactivation of a previous active service with a lower priority, wherein the combination of available apparatus forming a communications resource is performed by consulting a graph representing space of all possible combinations of apparatus and selecting an optimum solution on the basis of constraints specified, the optimum condition being defined as that where all the constraints are satisfied.
