“Task Interleaving” is one of the most powerful concepts in Warehouse Management System (WMS) theory and practice. Though more talked about than actually used, task interleaving is a key element of the cost justification for many new WMS implementations. Many companies also use task interleaving as an opportunity to drive additional savings after an initial WMS implementation, or to enhance results from in-house developed warehouse systems.

Task interleaving is an approach to assigning work to vehicle-based operators that seeks to drive efficiencies by linking different work task types (e.g., putaway and replenishment), rather than dedicating workers to a specific task type.
