摘要:An optimal management of a railway network constitutes a suitable and continuous requirement and it is necessary to assure to the users suitable standards of safety and comfort. It is, therefore, necessary that the companies that have the management of the infrastructures equip themselves with an adaptive and cognitive instrument of the network, so to have an effective technical support for the decisions, at the various levels of competence. In the present paper, an opportune methodology of approach to the problem is described. The proposed methodology is based on the construction of an informative network system, through the definition of one particular matrix n x m, with h = 1, ....., n; k = 1, ....., m, where n is the number of the system variables under study (homogenous arcs of the network, nodes, routes, etc.) and is the number of the considered characteristic indicators.
