Collecting GOH items within the storage address

Generally GOH(garments on hangers) items are stored on a steel rod of a length of 1.30m. Every such length of a rod has a unique address name which is stored on warehouse WMS system. Every item from inbound is scanned to those addresses or to rails(a warehouse equipment on four wheels) so these items could be picked and delivered to the stores where they are sold. On winter season generally on a length of 1.30m 40-60 items are stored. But in summer, 60-90 items are stored on such addresses. Suppose on a such rod 30 different merchandises are stored and 5 different items should be picked out of 80. Searching these items within the rod could consume a lot of time. There is a way to decrease this search time.

While we scan merchandise when we first got items from suppliers we can also store the scanning date and time info in the WMS system. So we can know the merchandise location within the specific rod. For instance: A1 is scanned on 14:30:12, A2 is scanned on 14:30:20, A3 on 14:30:41 and so on. So when time to pick some of these items has come, picking list can be given ordered to the address location and the merchandise within the address could be sorted according to scan time info taken while scanning on inbound.


Suppose you have 8 different sizes or models hang on a specific storage area. They are hang on the following order: A1-first, A2, A3, A4, A5, A6, A7 and A8 item is the last. A2, A5, A8 have to be collected. If the merchandise is ordered according to the description or model number the picking list could be like this: A8, A2 and A5. That is picker starts to search A8 from the beginning where A1 begins. After picker finds A8 item, he starts again from A1 and searches until he finds A2 and after A2 is found he starts his search again from A1 to find A5. And increases his picking time. But if picking list is sorted and printed by scanning time taken on inbound the pick list would be like this: A2, A5 and A8. Picker begins from A1. By picking A2 he starts searching from A3(not A1) and after collecting A5 he starts searching from A6 so he decreases picking time.

When I first implemented this feature picking quantity was increased by 25% per a picker increasing efficiency per picker.
