Inventory Management

Overview

Inventory management solutions aim to automate the inventory management process and increase accuracy and reliability. Every individual inventory item that is to be tracked receives an RFID tag or other similar Tracking technology. Each tag has a unique identification number that contains encoded digital data about an inventory item, for example the model and batch number. Tags are scanned by RFID or other readers. Upon scanning, a reader extracts the tag's ID and transmits it to the cloud for processing. Along with the tag's ID, the cloud receives data about the reader’s location and the time of the reading. Based on this data, an application states the location of the item with the corresponding ID, visualizes the findings and displays real-time updates about inventory items’ movements to the solution users, allowing them to monitor the inventory using a smartphone or a laptop from anywhere, in real time. There are also secondary benefits of inventory management. For example, Machine Learning can forecast the amount of raw materials needed for the upcoming production cycle based on the data about the inventory quantity and location, and reorder them as needed. It can also help in matching demand with supply more accurately as inventory movement is also a representation of demand.

Business Viewpoint

What are the benefits of an IoT-based approach on Inventory Management?

IoT-based inventory management lays a solid foundation for both process and business improvements. The benefits it offers include:

- Automation of inventory tracking and reporting: each item is tracked and the data about it is recorded to a big data warehouse automatically.

- Constant visibility into the inventory items’ quantity, location, and movements

- Inventory optimization: with the real-time data about the quantity and the location of the inventory items, manufacturers can lower the amount of inventory on hand while meeting the needs of the customers at the end of the supply chain.

- Identifying bottlenecks in the operations: manufacturers can reveal bottlenecks in the manufacturing process and pinpoint machines with lower utilization rates.

- Lead time optimization: By providing inventory managers with the data about the amount of available inventory and machine learning-driven demand forecasts, solutions based on IIoT allow manufacturers to reduce lead times.

What technology does Inventory Management use?

RFID

What are the main features components in RFID systems?

RFID systems feature three main components: RFID tags, RFID antennas and RFID readers.

- An RFID tag has an ID carrying the information about a specific object. It can be attached to any physical surface, including raw materials, finished goods, packages, crates, pallets, etc.

- An RFID antenna catches the waves from the reader to supply energy for tags’ operation and relays the radio signal from the tags to the readers.

- An RFID reader, which can be either fixed or handheld, uses radio waves to write to and read from the tags.

Data Viewpoint

How data is obtained in the system?

In an inventory management solution based on Industrial IoT and RFID, any individual inventory item that is to be tracked receives an RFID tag. Each tag has a unique identification number (ID) that contains encoded digital data about an inventory item, e.g. a model, a batch number, etc. Tags are scanned by RFID readers. Upon scanning, a reader extracts tags’ IDs and transmits them to the cloud for processing.

Deployment Challenges

What are the challenges and limitations?

The use of RFID technologies can be limited by the following factors:

- Since RFID tags can be attached to the items that are still in progress, manufacturers have to ensure that the tags do not influence the manufacturing process.

- Although RFID readers can scan through most of the non-metallic materials, they still may have troubles scanning through liquid and metal.

- The price of RFID readers can go to as much as $3,000 to $20,000 per item, installation and configuration included. Therefore, the cost of the products should be high enough for the tags and readers to pay off.
