This paper specifies a Decision Support System (DSS) devoted to manage Intermodal Transportation Networks (ITN). With the aim to support decision makers in the management of the complex processes in the ITN, we describe the architecture of a DSS and its main components. In order to obtain a generic DSS, we employ the Unified Modeling Language (UML) to describe the components and the architecture of the DSS and we apply the solutions based on Service Oriented Architecture, the simulation drivers and window services.
