Ports hold immense significance for human civilization. It plays a vital role of global economy as around 80% of trade and commerce of planet by value passes through the port. The economic benefits are often less directly tied to port activities and more linked to the dynamics of the supporting supply chains. Smart ports frequently utilize digital tools like automated sensors, data analytics, augmented reality, AI, ML, DL, big data, digital twins, etc to improve cargo movement, minimize waste and emissions, and provide superior services to shippers, shipping companies, customs authorities, local communities, and stakeholders. Future ports are modern and highly facilitated port which uses digital, automated and other smart technologies to enhance efficiency, accountability, sustainability, and competitiveness in monitoring, operations, and management. Smart 6^th Generation Port (6GP) is coming in near future to achieve optimum efficiency and extreme port service. Such ports will implement features like renewable energy sources, sustainable to climate change, natural calamities, and smart infrastructure, advanced security system for better logistics, service and optimum transportation. This analytical paper will investigate the perspective of smart 6GP to optimize the container/cargo handling in ports and to accommodate the advanced technology in near future.
