Logistic services are central to the design and management of any supply chain. Due to recent technological advances, modern supply chains are challenging traditional market boundaries in ways that both influence and are influenced by consumer behavior (e.g., Amazon, Alibaba, or JD.com). Economically speaking, corporations are changing along the way resources are being used in production. At the firm level, management decisions follow cost efficiency and risk management principles, pursuing a cost-risk tradeoff equilibrium. Theoretically, operations organized within the boundaries of the firm are just those for which the markets are unable to offer a more efficient alternative, whereas the link between buyers and sellers (i.e., demand and supply in the market) is intermediated by logistics services, such as transport, to mention but one. As technological innovation, social transformation, and consumer behavior threaten firms' traditional boundaries, logistics need to adjust and adapt to new and emerging challenges, its costs, and risks to end consumers.

The maritime supply chain is growing in complexity. Ports are at the crossroads of many activities, modes, and stakeholders, and are actively becoming digital hubs. Today, digital and physical connectivity go hand in hand. The port could benefit from taping the opportunities arising from digitalization and data integration since it helps to leverage external knowledge, engage stakeholders, create new decision-making anchors, lower the risk of certain investments, boost productivity and cut costs, and accelerate greening and digital transition, generating possibilities for just-in-time operations and optimizations. The chapter aims to apprehend the use of data science in the port sector. The state of the art in Brazil and Portugal are different. Even inside Brazil, there is no homogeneity of ports in the usage of digital infrastructure, cloud computing, or artificial intelligence. The existing inequalities hinder general cooperation between nations but, at the same time, reveal opportunities to approach specific nodes in the international supply chain.
