This paper employs modularity and mobility (M2) for designing recently introduced hyperconnected logistics hubs (HLH) for the Physical Internet, where parcels are encapsulated in modular tote-sized containers arriving in mobile racks, and these totes are consolidated by switching totes in shuffling cells to mobile racks with other totes with shared next destinations. The paper introduces the M2 framework and its modular standard-sized cells, racks and tote containers. Building on the overall HLH concept, the proposed M2 hub design is a major step forward with its on-the-fly transformability through operations to adapt to the dynamically changing sizes, mixes, characteristics, and flow of modular containers entering the hub and being consolidated and shipped within a short dwell time target. The paper uses a detailed case study to demonstrate the induced adaptability, adjustability, agility, efficiency, resilience, and scalability, and then it reports on an exploratory simulation experiment contrasting the performance of M2designs

Today the practice for distributing large products manufactured at few original equipment manufacturers (OEMs) consists of a dedicated Point-to-Point (PtP) logistics system, typically requiring long haul transport from the factory to the wholesale destination. A growing problem is the shortage of commercial drivers willing to be away from home for several days to move products cross-country. Hub relay network logistics systems are an alternative solution to P2P logistics systems that allow reducing drivers' away-from-home times. Operating a relay-based logistics system requires accounting for multiple interrelated operational decisions that become more complicated as the system becomes larger and encompasses more players. To deal with such complexity we propose utilizing a digital twin of the distribution and logistics system as a decision-making support tool to manage the system and make operational decisions efficiently. This paper explores the design and assessment of a hyperconnected relay network of transport hubs supporting the movement of durable goods from factory to wholesale destinations. It describes requirements and challenges in developing and implementing a digital twin for such systems.
