Not everything in the supply chain should be automated

With new advances in robotics and artificial intelligence, virtually every player in the supply chain is looking to some form of automation. Walmart is testing grocery-picking robots. Ryder partnered with Fetch Robotics to install drones, sensors and wearable technology in its warehouses. And in its latest earnings call, DHL said it was "seeing about 25% productivity improvement" from robotics. Automation, the companies bet, can increase efficiency, reduce costs and improve performance.
