A cardboard box in a truck driven by a person, maybe after it flew on an airplane, delivered to an address: This happens tens of millions of times every day and to most of us likely seems not only routine but also extremely low-tech. But every one of those hundreds of thousands of delivery drivers must decide the order in which to make each of their 100 or so daily deliveries, each selecting from literally trillions of possible combinations of routes in hopes of finding the shortest one, allowing them to consume the least amount of fuel, drive the fewest miles, lessen their carbon footprint and save their employer as much money as possible. UPS Senior Director of Process Management Jack Levis joins Another Think Coming to discuss the program his team spent a decade building to optimize those driving routes and the $50 million and counting it saves UPS every year.
