Using ingenious stacking algorithms, IPS Goods to Man can quickly calculate the optimum stacking required for each automated warehouse. This is done by combining order characteristics, specific article characteristics and additional parameters to be set by the user of IPS, e.g. family grouping, weight class, maximum height of carrier etc. Based on scores, the best result is used to retrieve the goods in the correct order from the automatic warehouse. When physically stacking the mixed goods, IPS provides every desired stacking robot with the correct stacking instruction. If manual packing stations are used instead of robots, the correct stacking instruction is displayed on a screen via IPS Stack by Instruction, so that the optimum result, the most filled carrier with the best quality that meets your wishes, is always realized.
