Planificación del transporte de aprovisionamiento en obras portuarias

Abstract

RESUMEN. Frecuentemente la ejecución de grandes obras infraestructurales, generan impactos significativos sobre el medio provocados por el transporte de importantes cantidades de material requeridas. Esto se agudiza aun más si la ubicación es en ámbito urbano, provocando serios problemas de congestión de trafico, emisión de contaminantes, polvo y ruido. En este artículo se presenta un modelo de simulación-optimización para la planificación de dicho sistema de transporte de abastecimiento, aplicándolo al caso de la construcción del nuevo puerto de Laredo (España), donde se calcula el reparto modal de carga entre camiones y barcazas con el objetivo de minimizar costes totales del sistema, desde un punto de vista económico, social y medioambiental. El coste total del sistema, se compone de los costes de operación de los camiones, el coste de operación de las barcazas y un coste de tipo social que representa el coste sobre los usuarios de transporte privado por el incremento de la congestión provocada por el flujo de los camiones en la red vial. Todo ello sujeto a restricciones medioambientales, asegurando que los flujos compuestos de vehículos privados y camiones no sobrepasan los limites de emisión de contaminantes y de ruido. Finalmente, consecuencia del análisis de los resultados junto con el pertinente análisis de sensibilidad se presentan una serie de interesantes conclusiones para una correcta gestión del sistema de transporte analizado.

ABSTRACT. The construction of large infrastructural works frequently causes considerable environmental impact as a result of the transport of large quantities of materials. This impact is further heightened when the work is located in an urban environment and tends to lead to serious traffic congestion problems together with pollution, dust and noise. This article presents a simulation-optimization model for the planning of site supply transport, applied to the construction of the new Laredo harbour (Spain), which calculates the modal distribution of loads between lorries and barges in order to minimize the total costs of the system from an economic, social and environmental point of view. The total cost of the system is composed of the operational costs of lorries and barges and a public related cost which represents the costs affecting private transport users as a result of traffic jams caused by the increased number of lorries on the roads. This is also subject to environmental restrictions in order to ensure that the combined flow of private vehicles and lorries does not exceed contamination and noise pollution limits. From the analysis of the results and on the basis of the pertinent sensitivity study, a number of interesting conclusions may be reached regarding the correct management of the transport system under study.
