Scheduling of straddle carriers in a container terminal

Report for the scientific sojourn at the University of California at Berkeley between September 2007 to February 2008. The globalization combined with the success of containerization has brought about tremendous increases in the transportation of containers across the world. This leads to an increasing size of container ships which causes higher demands on seaport container terminals and their equipment. In this situation, the success of container terminals resides in a fast transhipment process with reduced costs. For these reasons it is necessary to optimize the terminal’s processes. There are three main logistic processes in a seaport container terminal: loading and unloading of containerships, storage, and reception/deliver of containers from/to the hinterland. Moreover there is an additional process that ensures the interconnection between previous logistic activities: the internal transport subsystem. The aim of this paper is to optimize the internal transport cycle in a marine container terminal managed by straddle carriers, one of the most used container transfer technologies. Three sub-systems are analyzed in detail: the landside transportation, the storage of containers in the yard, and the quayside transportation. The conflicts and decisions that arise from these three subsystems are analytically investigated, and optimization algorithms are proposed. Moreover, simulation has been applied to TCB (Barcelona Container Terminal) to test these algorithms and compare different straddle carrier’s operation strategies, such as single cycle versus double cycle, and different sizes of the handling equipment fleet. The simulation model is explained in detail and the main decision-making algorithms from the model are presented and formulated.

Sistemi di trasporto collettivo di tipo Automated People Mover: applicazioni in ambito areoportuale

Con il seguente documento si vuole esaminare l'utilita trasportistica dei sistemi di trasporto del tipo Automated People Mover passando da un inquadramento storico generale all'uso dei sistemi nell'ambito aeroportuale dall'inizio degli anni '60 fino ai tempi piu moderni. Dopo avere analizzato le configurazioni e le caratteristiche tipiche dei sistemi APM in ambito aeroportuale si definira quale tipologia di infrastruttura e stata privilegiata negli aeroporti europei e mondiali. Successivamente si prendera in esame lo stato dell'arte dei sistemi APM installati nell'aeroporto principale di Parigi e uno dei piu trafficati del mondo, l'Aeroporto Internazionale Charles de Gaulle; e del sistema installato nell'Aeroporto Internazionale Galileo Galilei di Pisa.
