OATSystems, based in Waltham, Mass., this week unveiled an
RFID software product designed to help manufacturers keep close tabs on their work-in-process (WIP) and assets. The
Asset Tracking and Work-in-Process Solution is intended to help improve supply chain processes, track deliveries, reduce errors and cut inventory levels, by making it easier for companies to configure how their RFID systems track materials throughout the manufacturing and distribution processes. A primary component of the software is a set of 80 pre-programmed use cases (business processes) that can be leveraged to model real-world business processes.
The software can trigger real-time alerts and other responses by comparing RFID data captures against rules created in the use cases. For instance, a clamps maker might choose to
tag its clamps at the start of the manufacturing process and track the WIP. Using a Web-based graphical user interface (GUI), the company can define the locations at which interrogators will be installed to capture
RFID tag data; define the products, parts or materials and their attributes; create associations between the RFID tags' unique ID numbers and the parts they represent; and add business logic to trigger an alert if a tagged clamp fails to reach a given point in the process within a specified amount of time.
The Asset Tracking and Work-in-Process Solution allows for alerts to be sent via e-mail or cell phones. It can also trigger lights mounted on light stacks—cylindrical posts that
flash lights to indicate whether a process should keep running (typically green) or stop (typically red)—often found in manufacturing and distribution environments.
The prepackaged use cases can be modified via a high-level graphical tool, says Paul Cataldo, OATSystems' VP of marketing. "It is pretty easy for an end user to use, without having to resort to programming," Cataldo states. "For example, you might have a more involved case where the product you are tracking is going through multiple stages of assembly, so you might want to modify the process scenario." The software includes a series of reports and analytics so companies can monitor trends regarding WIP and distribution history.
The Asset Tracking and Work-in-Process Solution is built on a Service Oriented Architecture (SOA), a software framework or methodology for building business functionality and applications leveraging Web standards such as
XML. As such, Cataldo says, it can be more easily integrated with back-end systems, such as enterprise resource planning (ERP) systems. The software runs on Windows or Linux operating systems and is configured to support a variety of RFID tag types, including passive, active and sensory tags. It also supports a range of RFID interrogators, including those compliant with the
EPC Gen 2 UHF and
ISO 15693 HF standards. The company is currently testing the software's support for
Wi-Fi-based RFID tags and interrogators, and plans to make such support a permanent feature.
