inefficiencies before rfid
Inefficiencies before RFID

Time –consuming and unreliable stock taking

Remarkable variances between accounting and physical stocks

Overstated or understated inventory levels

Difficulty in locating the pallets on storage racks during order assembly

Mistakes during loading

Product obsolescence due to overstocked inventory.

No establishment of unforgiving rules for pallet storage

rfid enabled storage process

1. Attach RFID labels on pallets

2. Link Pallet Barcodes with Pallet RFID Label – Update WMS

3. Forklift Truck reach Pallet RFID Label

5. Reading of Storage Rack RFID Label – Confirmation of correct storage location

4. The Storage Location is shown on the terminal via WMS

RFID-enabled Storage Process
rfid enabled full pallets picking

1. FLT Driver reads on the terminal Pallets & Location to retrieve

2. Confirmation of correct Pallet pickup

RFID-enabled Full Pallets Picking
rfid enabled shipping process

1. Move assembled orders to the loading area

Stock Taking by moving properly equipped FLT through the aisles

remarkable benefits
Remarkable Benefits

Achieved near 100% pallet traceability of pallets through the distribution center

Improved correct storage location of pallets by more than 25%

Expedited stock taking improved by 40%

Faster pallets movement by 30% – The FLT operator completes pallet storage and retrieval on his driver’s seat – no need to get off for pallet – rack scanning etc

80% reduction in shipment errors

Overall process improvement of 20%

RFID IMPLEMENTATION of DIAKINISIS CASE

Process C (Picking)

Process B

(Storage)

Process D (Shipping)

NEW Process

(RFID LABELING)

  • Alternative RFID implementations
    • Numerous possible ways of implementing RFID within an warehouse processes

STORAGE

…is not supported by RFID…

  • RFID process redesign problem
      • Different implementation  different value of RFID
      • no clear cut answer as to which RFID implementation is the best
    • IT IS IMPORTANT TO
    • design differently configured to-be implementations and
    • decide on a specific one based on a credible evaluation of the alternatives
