ABSTRACT

A product order fulfillment system includes: a multi-level transport system,
each level thereof having a corresponding independent asynchronous level
transport system; a lifting transport system with more than one independent
lift axis, in a common lift cell, each of the more than one independent lift
axis being configured to independently hold and transport the at least one
case along a trajectory; and a controller operably coupled to the multi-level
transport system and the lifting transport system; where the asynchronous
trajectories of the common lift cell output an ordered sequence of mixed cases
in accordance to a predetermined case out ordered sequence of mixed cases; and
where the controller is configured to heuristically generate optimal
trajectory solutions for the asynchronous trajectories, and assign the at
least one case to at least one asynchronous level transport axis based on at
least one qualitative metric characterized by the optimal trajectory
solutions.
