“…This model also considers the volume of the product to determine the storage space needed. We have also found some studies regarding the pallet loading action, for instance, Abdou and El-Masry (2000), propose a new pallet loading technique for boxes of different dimensions, considering the base dimensions and the height. Li et al (2018) propose a stacking method for an OP system that combines two-dimensional and three-dimensional vision.…”

This paper is inspired by a manual picking retail company where shape and weight constraints affect the order-picking process. We proposed an alternative clustering similarity index that considers the similarity, the weight and the shape of products. This similarity index was further incorporated in a storage allocation heuristic procedure to set the location of the products. We test the procedure in a retail company that supplies over 191 stores, in Northern Portugal. When comparing the strategy currently used in the company with this procedure, we found out that our approach enabled a reduction of up to 40% on the picking distance; a percentage of improvement that is 32% higher than the one achieved by applying the Jaccard index, a similarity index commonly used in the literature. This allows warehouses to save time and work faster.
