The values of the variable input parameters X and Y could be adjusted to identify the best scenario. There were two variable parameters X and Y, which DHL engineers were not sure about: capacity of the recirculation conveyor (X), and the time after which orders were flushed from the sorter (Y). Three employees would sort the boxes and drop them on the conveyor. They decided to have three entry points for weight classes: heavy, medium, and light. Input data for the simulation (click to enlarge) This data provided the arrival sequence of boxes, their order numbers, and their dimensions. The developers used historical data as inputs. DHL used AnyLogic Material Handling Library for the simulation model. To meet these goals, they decided to use AnyLogic simulation. If yes, then what are the optimum operating parameters for the system.If the system can handle peak day volume.The feeding conveyor would be switched after every pallet completion.ĭHL required a simulation method implemented in their planning strategy. There were four palletizers at the end of divert conveyors. A screen at the entry point would notify operators about available lines and boxes on the recirculation conveyor. In doing so, they would not damage the medium and light boxes. It was essential that the heaviest packages go to the bottom of the pallet. DHL planned to sort boxes by their weight. Orders would be sorted and palletized by a narrow belt sorter. This system was supposed to include a reject conveyor, eight divert conveyors, and a recirculation conveyor. Thus, DHL needed automation to support the sorting process. Compared to the previous cases, there would be much larger orders. ProblemĭHL Supply Chain wanted to install a box sorting system for the new facility. In these case studies small and medium size e-commerce orders were considered. Optimizing e-commerce warehouse operations.To learn more about DHL warehouse modeling in AnyLogic and the optimization tool for order picking, read the following case studies: Their integrated logistics solutions drive efficiency and improve quality.
