US Patent 10147129 Determining collections of similar items

Systems and methods are provided for identifying groups of items that consumers are likely to purchase together. In some embodiments, a graph may be generated based on information regarding items that have been previously ordered together and information regarding the similarity or affinity between items. The graph may be analyzed to identify groups of items, wherein consumers are likely to order items in each group together. In some embodiments, each group of items may be assigned to a storage facility, and a list representative of the items stored in that storage facility may be modified to include the items in the group assigned to the storage facility.
