Physical internet is an academic concept and transformative research field focused on designing and operating global logistics systems based on principles analogous to the digital internet. It investigates the creation of an open, interconnected network for physical goods movement, aiming to enhance efficiency, sustainability, and resilience across supply chains. Key characteristics include the encapsulation of goods in standardized, modular containers, the use of common protocols and interfaces for handling and transport, the sharing of logistics infrastructure, and dynamic routing and synchronization driven by pervasive digital information. Its significance lies in its potential to fundamentally restructure how goods are moved, leading to reduced costs, decreased environmental impact, and increased adaptability.
