Abstract
We present a Decision Support System to assist operators of rail freight networks in planning their activities and daily operations. The DSS is interfaced with the information system of the rail freight company in order to access the most complete and up-to-date information on the location of rolling stock over the rail network, and the maintenance status of each wagon, on the current state of train circulation. Given static information on the characteristics of the rolling stock fleet, and given the scheduled connections among terminals, an efficient rolling stock circulation plan, i.e. the routes of train compositions periodically connecting two or more terminals, is computed. Thanks to dynamically updated information and on the above mentioned circulation plan, a set of efficient train dispatching assignments, that is, the assignment of incoming train in a terminal to outgoing train rotations, is also obtained and proposed to the operational manager.
