The purpose of this function of the system is:

• to ensure that designated product pick faces are replenished in an optimum manner
• to ensure that the minimum number of part pallets of any one product are kept in stock

The system can interleave these movements with put away and picking movements to ensure optimum use of material handling equipment and manpower.

Pick face replenishment can also take account of the demand profile for each SKU to allow replenishment in line with incoming and forecasted orders.
