What is Task Interleaving
A WMS capability in which the same worker is directed to perform consecutive tasks of different types, rather than repeating the same task. The classic example of this is a full pallet putaway followed by a pallet replenishment for a case pick area coming from a reserve location near to the putaway location.
The idea is that total travel distance is reduced by the reduction in “dead-heading,” meaning a fork-lift driving with no load. Task interleaving is talked about quite a bit, but it is used less often than many might think due to layout issues and added complexity.
