If our water flows freely when we open the tap, most of us don’t think much about the reservoir where it originated or the plant where it was treated. We are even less likely to think about the network of pipes the water passed through to reach our sink. Similarly, when we buy a product in a shop or pick up an online purchase delivered to our doorstep, few of us consider the complex links in the supply chain that put that product in our hands. But a truly efficient supply chain that is fully optimized at every step, from manufacturing to inventory management to fulfilment, is what gets products into people’s hands as fast as possible, and with the least amount of environmental impact. Today, with the emergence of 5G cellular networks, we are on the brink of a revolution in supply chain and logistics.
