Waterway, Anchorage, and Berth Scheduling: A Case Study on Port of Manila

Abstract

Maritime transport is a huge instrumental engine of trade economy following the nation's GDP growth. Short turnaround times and reduced waiting times play an important role in increasing countries' port competitiveness. Port operators need to establish an efficient port schedule through the minimization of ships' completion times. In this regard, vessels need to undergo sequential phasesinbound passage in waterway, anchorage queuing, berth allocation, and outbound passage. Technical limitations must also be addressed such as traffic capacity, safety distance, and berth spatial constraints. In this paper, the dependency of these phases will be solved in an integrated manner through the reformulation of the classic MM-RCPSP. The novelty of multi-alternative waterways considering safety distance will be explored, and port capacity restrictions are imposed to effectively replicate the real-life port situation. Data set from Port of Manila is generated to verify and validate the feasibility of the established MILP model. Computational results show that the proposed approach is effective in minimizing the completion time of vessels with a decrease of about 16.51% from the actual port performance.
