Picking Solutions that Work by Andrey Kras November 1, 2017 www.daifuku.com
What was the life like for a person in old times? Not very diverse… After lunch… not much
As mankind was growing… Diversity did get better… but only a little
But no time of the past compares to our time in terms of Things we consume Things we own
Today, people ARE what they CONSUME And they consume more For that, they shop more Hence, they buy more
The more they do so, the more elaborate their shopping habits become Colors, styles multiply
Ownership of things defines people, therefore they will increasingly continue to buy more and more Nothing would stop them
To add to this, people are increasingly becoming compulsive and hence immoderate buyers
Going to a real shop is still an option
But many prefer shopping online
Waiting for deliveries for weeks is no longer tolerated. Delivery times are getting shorter
Next day delivery is no longer an option. Same day delivery is a demand of the day. And companies strive to meet the demand…
What do these trends mean to logistics industry? A skyrocketing increase of number of orders Fewer lines on orders Order 890782373 Order 890782373 Order 890782373 Item Qty Order 890782373 Item Qty Order 890782373 iPhone 7 1 Item Qty Order 890782373 iPhone 7 1 iPhone 7 case 1 Item Qty Order 890782373 iPhone 7 1 iPhone 7 case 1 Item Qty Order 890782373 iPhone 7 1 iPhone 7 case 1 Item Qty Order 890782373 Fewer quantity per order iPhone 7 1 iPhone 7 case 1 Item Qty iPhone 7 1 iPhone 7 case 1 Item Qty iPhone 7 1 iPhone 7 case 1 Item Qty iPhone 7 1 iPhone 7 case 1 iPhone 7 1 iPhone 7 case 1 iPhone 7 case 1
Burden of stock keeping gets pushed up the supply chain Nearly daily stock replenishment in small quantities Why? Because no one wants to store at stores any more
What does this mean to a manufacturer? A finished goods warehouse is no longer for storage only A FG warehouse acts as a DC and, in addition to unit loads, ships often piece-picked items in small quantities.
What does this mean to an importer? An increased demand for storage, since inbounds are even less balanced with outbounds Again, increasingly less outgoing unit loads, more loose cases, or even pieces
What does this mean to a traditional layout of warehouse ? Pallet remains the major unit of storage Increasingly more space is given to picking operations: pre-picking, batch picking, order consolidation
Picking in a traditional warehouse looks something similar to this Storage Picking

Creating picking zones and optimizing pick faces (A to B to C) do reduce walking of each worker but adds a whole another new operation. Order Consolidation
1 2 3 4 5 9 6 7 8 Batch picked Order picked
With multiple few-line orders, the time required for order consolidation may outstrip by far the time required for batch picking.

Automation of picking operations eliminates all these inefficiencies
Why? No more walking, nor searching The correct load by itself comes under the picker’s hands
No more scanning of rack, nor of box* Verification is performed automatically *Scanning of pieces may be mandated in some cases
No more batch picking Pick stations allow multiple- order picking at the same time
No more need in order consolidation Pick stations allow dedicated order picking* *Some large-scale solutions may require pre-picking and hence consolidation
Therefore , Picker does nothing else but picking
