Model of priority assignment of vessel traffic in a multiport access channel under tidal conditions

Abstract

ABSTRACT : This work addresses the problem of scheduling vessels (incoming and outgoing) in access channels subjected to tidal action. The document is divided into 4 sections. The first one gives a context of the problem, its components and a literature review and research trends identified in the literature. The second section contains the modeling of the problem under the linear integer modeling perspective. Chapter 3 outlines a case study (Buenaventura’s multiport terminal) and describes its characteristics and data collection methodology. Finally, in chapter 4 some experiments are presented with their results aimed at answering these research questions: 1. What is the minimum safety time that can be available between vessels without affecting safety and the minimum waiting times of the vessels? 2. What is the minimum average speed that can be used in the navigation of the vessels without affecting the safety and the minimum waiting times of the vessels? 3. Can the best times for annual navigation in the channels be determined considering the variations of the tide? 4. What is the maximum capacity of entities supported by the model without significantly affecting the processing times of the data?
