Abstract: A dynamically automated warehousing system including a three-dimensional storage volume having a plurality of horizontal storage levels which are vertically offset from each other, each level defining a grid of mutually adjacent palletized load storage/travel locations, at least some of the storage/travel locations being accessible from multiple directions, a three-dimensional palletized load storage/travel controller operative to dynamically control placement of palletized loads to and removal of palletized loads from palletized load storage locations and being operative to changeably designate a first plurality of the storage/travel locations as palletized load storage locations and a second plurality of the storage/travel locations as palletized load travel locations at a first time, and at a second time to designate a third plurality, different from the first plurality, of the storage/travel locations as palletized load storage locations and a fourth plurality, different from the second plurality, of the
