Simulation-Based Performance Assessment Framework for Optimizing Port Investment

Abstract

This paper demonstrated a new framework for port investment optimization that includes a three-stage process. First, a performance-based approach was applied to determine the margins of ship responses under external impacts and thereby establish operational safety policies. Second, a discrete event simulation model for assessing port performance was developed under various investment scenarios. A complex system of different underwater structures and port processes (such as access channel, water basin, anchorage area, tug usage, and mooring facility) was included in the model together with traffic rules and operational safety criteria. Finally, we generated optimal investment planning through cost strategy analysis. Our case study of Lien Chieu Port showed that the new framework is practical and effective in optimizing port investment by balancing between the port dimensions and cargo handling rates. The accuracy of the proposed approach could be further enhanced by introducing additional practical aspects of port operations into the simulation model.
