A carousel used in a restocking system is comprised of a drive track. A plurality
of bins are arranged into rows, with the rows being driven by said drive track.
A drive mechanism, e.g. an electric motor, drives the drive track. A sensor is
provided to sense the position of the rows of bins. A processor is responsive to
the sensor and data representative of a plurality of picks for more than one order
for controlling the drive mechanism. By combining picks from different orders into
a batch, the time spent driving the rows and time between picks is minimized. The
carousel may be divided into a plurality of columns, each with its own drive track,
drive mechanism, and sensor, to enable several rows to be brought into a pick position
simultaneously. Various methods and forms of restocking packages are also disclosed.
