the ERP functioning and features, the inventory operations management is heavily dependent upon WMS System.

WMS system is different from an ERP based inventory system in the sense that WMS manages inventory but manages inventory operations and warehouse operations. Though it mirrors the inventory that lies in ERP, the rest of the operations that are carried out through WMS are different and operations intensive. Until a few years ago the inventory operations used to be carried out with basic WMS where most of the operations were manual. Put away lists and pick lists had to be printed and issued to the operators, who had to note down the bin location and the pallet ID etc on the slip and give it back to the operator to do the data entry into the WMS and update the systems.

With the introduction of scanning technology things became a lot easier where barcodes labels could be pasted on the inventory which could then be scanned via hand held or wireless scanners and the data could get uploaded into the WMS. This was further replaced by RF scanners, which work in real time basis. Today most of the warehouse operations are carried on through RF Scanners, which are like the extension of the WMS and are connected to the system on real time basis.

The operators can now download tasks, carry out the tasks and upload confirmation of task completion into the system through RF scanners. This has not only improved operations efficiencies and ensure better housekeeping but has greatly improved the inventory as well as data efficiency. Both ERP and WMS systems along with RF technology have helped improve inventory visibility, accuracy and operations efficiency, resulting in faster operations, leaner inventory and good warehouse management practices.

RF Tag IDs have made an entry into the inventory and supply chain arena and are currently being adapted by retail and textile industries as well as aero spares industry etc. Tag IDs will provide inventory visibility at all times throughout the supply chain and thereby ensure inventory accuracy. They are expected to help cut down and ease a lot of operational processes too. However exorbitant cost of the RF tags IDS has been the entry barrier that kept the industries from adapting this technology. The rates are dropping fast making it viable for all industries to adopt these into the inventory management and operations systems.
