One of main activy in warehouses is the orderpicking process. It’s the process where (parts of) orders are assigned to one or more orderpickers. Different strategies can be applied:
- Zoning policy: The total pick area may be divided into picking zones, to be served by different orderpickers. Two alternative policies exist:
-
- Parallel zoning or
- Sequential zoning.
- Batch policy: Orders are picked one by one (single order picking) or in batches (batch picking).
If Batch picking policy, Picked orders must be sorted in one of two sorting policies:
-
- pick and sort (sequentially)
- sort while pick (simultaneously).
- Routing policy: define the sequence of retrievals and the route to visit the retrieval locations.
Dwell point policy may prescribe the position of idle orderpick equipment.
