We have completed a pilot project of a real-time location system in the Fresh Logistics fresh products warehouse. The aim of the system was to record the movement of forklifts, visualize this movement in real time and create so-called. Spaghetti charts for selected carts and selected period. The system locates the trolleys with an accuracy of approx. 25 cm both between the high storage racks and in the low storage warehouse. The solution also allows you to identify the trailer under the loading dock and monitor the temperature. The system is a solution that allows detecting and eliminating wastes in accordance with the principles of "lean".
