FREIGHT RAILWAY TRANSPORT: CRITICAL VARIABLES TO IMPROVE THE TRANSPORT APPLIED TO INFRASTRUCTURE COSTS AND ITS ASSOCIATED TRAFFIC FLOW

The developed societies have as challenge, among others, to achieve a mobility development based on economic models of low carbon and energy efficient, making it accessible to the entire population. In this context, the sustainable mobility seems to meet the economic, social and environmental needs, minimizing their negative impact. There are three factors that are relevant: (1) infrastructures; (2) modes of transport more ecological and safe, and (3) operations and services for passengers and freights.The objective of this research is to provide guidance to investment in sustainable transport infrastructures that are truly useful and effective. In particular we have studied the case of the railway, using the following information: details of the infrastructure; cost of construction (per kilometre); maintenance cost, and life cycle. This information may be relevant to consider their possible business models.The methodology of this research was focused in the detailed analysis of the infrastructure use and maintenance criteria, the market opportunities for freight development and the available data to validate the obtained results from the software tool reached in this work. Our research includes the different following aspects:• Evaluation of the supported traffic by the rail line.• Relevant items to be considered in the rail infrastructure. Defining the track, we can group items in two sets: civil and rail installations.• Rolling stock available. Locomotives and wagons are modelled to introduce the data as convenience for the user.Besides our research includes the development of software, Decision System Tool (DST), for studying the construction and maintenance cost of railway infrastructure. It is developed in a common and open source program, providing the user the interaction with the critical variable of the line. It has been adjusted using the following references: MOM PlanCargorail; EcoTransIT, and Projects funded by Framework Program of EU (NewOpera, Innotrack and Sustrail).

GESTION DE BASES DE DATOS VISUALES EMPLEANDO SISTEMAS DE INFORMACION GEOGRAFICA.

Geographic Information Systems are developed to handle enormous volumes of data and are equipped with numerous functionalities intended to apture, store, edit, organise, process and analyse or represent the geographically referenced information. On the other hand, industrial simulators or driver training are real-time applications that require a virtual environment, either geospecific, geogeneric or a combination of the two, over which the simulation programs will be run. In the final instance, this environment constitutes a geographic location with its specific characteristics of geometry, appearance, functionality, topography, etc. The set of elements that enables the virtual simulation environment to be created and in which the imulator user can move, is usually called the Visual Database (VDB). The main idea behind the work being developed approaches a topic that is of major interest in the field of industrial training simulators, which is the problem of analysing, structuring and describing the virtual environments to be used in large driving simulators. This paper sets out a methodology that uses the capabilities and benefits of Geographic Information Systems for rganising, optimising and managing the visual Database of the simulator and for generally enhancing the quality and performance of the simulator.

SIMULANDO LA INYECCIÓN DE PLÁSTICOS. NUEVAS FORMAS DE APRENDER LOS PROCESOS.

El presente trabajo describe una aplicacion que se presenta como alternativa para ampliar y reforzar la gama de recursos que el aprendiz novel dispone para adquirir conocimientos practicos en inyeccion de plasticos, y asi poder utilizarlos con exito en el marco del diseno, seleccion y parametrizacion del proceso de inyeccion. Por medio del empleo de criterios de decision borrosos, similares a los propios del conocimiento de un disenador experto, y que resultan imposibles de plasmar en ecuaciones de comportamiento del proceso, se desarrolla una maquina virtual de inyeccion de plastico, y por tanto un sistema que permite evaluar, por ejemplo, la bondad de los parametros de transformacion elegidos para un proceso, dando como salida aquellas respuestas que proporcionaria un disenador experto. Se ha desarrollado un panel de control virtual similar al de las maquinas de inyeccion reales operable por los usuarios, cuya respuesta varia de acuerdo al modelo borroso incorporado y a los parametros introducidos por el usuario al utilizarlo. Esta maquina produce piezas virtuales inyectadas que muestran un nivel de defectos que es funcion de los valores de los parametros seleccionados por el usuario, permitiendole una nueva seleccion de los mismos hasta la obtencion de las piezas correctas facilitando asi el aprendizaje de la seleccion de condiciones.
