Management of internal delivery vehicles in maritime container terminals

Abstract

Maritime container terminals are complex infrastructures to manage in transportation industry due to their highdegreeofuncertaintyarisenfromthelimitedandchanging information. The present paper addresses the operational managementoftheavailableinternaldeliveryvehiclesonthe yard of a maritime container terminal under random changes in the simultaneous movement of import, export, and transit containers. Themaingoalofthepresentedproblemistooptimize the usage of the available internal vehicles in terms of working time in scenarios where synchronization is required when accessing to the different pick-up and drop-off container locations. An efficient variable neighbourhood search is here proposed to dispatch, route, and schedule the existing vehicles while adapting their behaviour to both the arrival of new information and unforeseen changes in the existing information related to the environment under analysis. The computationalexperimentsindicatethesuitableperformance of the proposed technique on a wide range of realistic scenarios.
