Big multinational DHL has just recently opened a logistic center in Regensdorf a locality in Switzerland. Receiving an average of 35.000 boxes per day, they decided on a non-inventory policy, where everything that comes in in one feasible day, comes out in less than 24 hours.
I have got the opportunity to get insider information and footage of how they do it.
Firstly, packets and boxes are downloaded from an arriving truck into a conveyor belt, and they are lead inside the full network of mechanical belts that will bring the package into the specific destination to be delivered to an awaiting truck. How do the packets know where do they have to go? The answer is in the intelligent cell inside the transportation belt.
A large 180 degrees’ bar code scanner reads the code attached to the package (which always has the reference number in two different faces of the box) once the scanner has processed the relevant information about the delivery area, it transfers the information of the package to the intelligent cell in the belt. The belt follows its natural and general path but when it detects the location in which the box needs to go, it stops and drops the package in the correct pick up area.
Once the order is fully completed the truck comes, uploads all the packages and is ready to deliver.
I have created a short video on how it is done and you can see it in the following link.
