The model produces optimal designs for one two and three-cross-aisle warehouses which are called chevron leaf and butterfly designs. We then use a more accurate discrete model to show which designs are best for a wide range of warehouse sizes. We show that the chevron design which is new to theory and to practice is the best design for many industrial applications. © 2012 IIE. © 2012 Elsevier B.V.
