In ShipStream a Zone is a numeric identifier which associates one or more Racks. Sharing the same Zone indicates that Racks are in physical proximity to each other for the purpose of batching so that picking batches may be composed in an efficient manner which reduces wasted travel time across a warehouse.
The Batch creation process starts with a "seed" order and then starts adding other orders to the batch based on similarity such that the picker will have the least number of picks or the least amount of travel between picks as possible. This process starts with the pick Locations, then expands out to cover the Locations on the Racks, then the Racks in the Zones then the Neighbors of the Zones and finally the whole warehouse.
The "name" of the Zone. A value in the range from 1 to 63. This is a required field.
The neighboring Zones to this Zone. This is a comma-separated list of Zone Numbers. This is an optional field.
Define the picking order for this Zone. The Picking Order can be used to define a high-level Picking Path by defining a path from Zone to Zone.
Defining the Zones
When defining Zones different areas of the warehouse may need different size Zones. You may also want some Zones to have neighbors and others to not have neighbors. i.e.: Small item picking areas you may want to have smaller and allow neighboring Zones. Whereas Bulkier items you may not want to have Neighbors so that the Batches don't expand into Neighboring Zones.
