The complexity of a WMS implementation varies with dimensions and characteristics of item in the warehouse. The storage options for each item are required, for example if the item can be stored separately, in box, pallet or if it can be stacked. Each item must be reviewed to see if it is physical limitations on its storage, such as requiring refrigeration.
Capacity calculations require the physical size and weight of the item as well as the dimensions of all the storage bins or racks in the warehouse.
The system requires decisions or configuration to be made on how items are to be placed or removed from the system.
