Planificacion del transporte de aprovisionamiento en obras portuarias

Planning of site supply transport for port works

Frecuentemente la ejecucion de grandes obras infraestructurales, generan impactos significativos sobre el medio provocados por el transporte de importantes cantidades de material requeridas. Esto se agudiza aun mas si la ubicacion es en ambito urbano, provocando serios problemas de congestion de trafico, emision de contaminantes, polvo y ruido. En este articulo se presenta un modelo de simulacion-optimizacion para la planificacion de dicho sistema de transporte de abastecimiento, aplicandolo al caso de la construccion del nuevo puerto de Laredo (Espana), 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 economico, social y medioambiental. El coste total del sistema, se compone de los costes de operacion de los camiones, el coste de operacion de las barcazas y un coste de tipo social que representa el coste sobre los usuarios de transporte privado por el incremento de la congestion provocada por el flujo de los camiones en la red vial. Todo ello sujeto a restricciones medioambientales, asegurando que los flujos compuestos de vehiculos privados y camiones no sobrepasan los limites de emision de contaminantes y de ruido. Finalmente, consecuencia del analisis de los resultados junto con el pertinente analisis de sensibilidad se presentan una serie de interesantes conclusiones para una correcta gestion del sistema de transporte analizado.

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.
