    Abstract

    La necesidad de incorporar multiplicidad de objetivos en la planificación del transporte suele dar lugar a conflictos. A menudo resulta imposible combinar los objetivos en una función de valor global, lo que hace necesario el tratamiento de estos problemas desde la óptica de la Programación Multiobjetivo. Si no se dispone de información adicional, el tratamiento de un prob lema multiobjetivo consiste en la obtención del conjunto de puntos no dominados, pero aún en los casos en que se puede determinar dicho conjunto, este procedimiento proporciona demasiadas alternativas y suele ser de difícil interpretación para el decisor. En este trabajo analizamos la aplicación de un procedimiento para la reducción del conjunto de soluciones no dominadas en un problema de transporte donde se han establecido tres objetivos. El procedimiento está basado en la inclusión en el modelo de información adicional sobre la importancia que el decisor asigna a los diferentes objetivos, y permite la incorporación de nueva información de manera secuencial. The multiplicity of objectives in transportation planning often leads to conflicts among them. Further, frequently it is impractical or impossible for the decision maker to combine the objectives into one averall value function. With no additional information, solving a multiobjective problem menas finding the set of nondominated alternatives, but even when it is possible to obtain this set, the procedure generates too manyu alternatives and it is often not very useful for the decision maker. In this paper we analyze a procedure to reduce the size of the set of nondominated solutions for a tranportation problem where three objectives have been established. The procedure is based on the inclusion in the model of additional information about the importance of the different objectives, and permits sequential incorporation of new information.
