RFID is having a broad impact on manufacturing operations, including information management, manufacturing execution, quality control, compliance, tracking and genealogy, asset management, inventory visibility, and labor productivity.

For years, manufacturers have made investments in providing production with supply chain information it depends on to optimize inventory, while at the same time improving production efficiency, flexibility, and responsiveness.

Accurate, detailed, and timely information delivered by new generation MES systems is critical in getting the most value out of existing investments in automation.

For a broad cross-section of manufacturers that have not made substantial investments in MES, RFID provides a method to close some functional gaps, particularly related to tracking and genealogy and compliance management. For these manufacturers, a combination of RFID investments and incremental, hut functionally focused, MHS applications (such as tracking and tracing) can quickly and cost-effectively deliver functionality that parallels comprehensive MES solutions.

An Accenture white paper describes in detail the potential opportunities to leverage RFID on the plant floor. RFID initiatives will immediately influence these key areas.

Manufacturing information

By combining RFID with existing manufacturing information systems investments that drive both MES and FRR a much more potent information supply can drive production efficiencies, asset utilization, quality, and other production measures to much higher levels.

For a broad cross-section of manufacturers, RFID technology potentially provides a means to close some functional gaps, such as those related to compliance management, tracking, and genealogy.

By applying RFID technology incrementally across the plant floor, manufacturers can seamlessly integrate the new information captured by RFID, without disruption into existing, reliable, and industrially hardened control, visualization, and information infrastructure. Existing MES systems can then he updated to deliver the necessary RFIl) data management and reporting and also synchronize production with the RFID-enabled supply chain.

In order to deliver information from REID downstream out to the supply chain (ERP) and upstream into production (MES), existing information infrastructure must convert to co-exist with emerging EPC standards and IT that includes software and application management such as device brokers.

Once this information shares across the enterprise and plant floor, receiving, manufacturing, warehousing, and shipping operations must coordinate and execute in the context of orders and customers.

Regardless of how much effort and dollars go to RFID on the enterprise level, poor management and execution of RFID efforts at the plant level could drive down potential benefits.

For manufacturers, it is becoming increasingly important to design and integrate RFID information and solve connectivity issues related to plant floor and warehousing execution in such a way that new information integrates into plant floor reliably and through industrially hardened conduits.

In addition, deploying an REID network for a manufacturer is of little or no value unless the information it provides is accessible using an array of hardware and software that ties together and back into the plant for execution and action.

For the most part, manufacturers have to take raw data from RFID readers and determine how to get it into MES and control systems that drive manufacturing. In addition to delivering the right information at the right time to an MES or control system, the rules concerning manufacturing execution such as control, scheduling, routing, tracking, and monitoring must all change to collect and be responsive to new RFID-information.

In addition to managing operations on the plant floor, warehousing operations must also receive support from an information perspective to ensure the right products get to the supply chain at the right time.

Quality control and compliance

RFID has the potential of complementing MES in terms of providing new streams of real-time data that can support existing Eean and Six-Sigma programs.

RFID information can ensure the correct labor, machine, tooling, and components are available and ready to use at each processing step, thereby eliminating paperwork and reducing downtime.

Furthermore, process steps could be controlled, modified, and even reconfigured in real time as inbound materials, parts, and assemblies move through manufacturing.

As raw materials turn into finished assemblies, triggers could be set off, controlling either inbound materials and thereby impacting work-in-process inventory or post-process inventory.

By tagging raw materials with detailed specification information, alerts could automatically trigger at mixing operations if an incorrect formulation is imminent. This can help reduce scrap rates and increase yield, assuring a high degree of reliability and quality in processing.

For manufacturing operations that require a high degree of compliance with governmental standards and regulations in particular, RFID can provide additional information streams to support existing MKS activities enabling tighter tracking, verification, and validation of processes including those involving 21 Ct-R Part 11 compliance.

Tracking and genealogy

Increasingly demanding IT)A quality requirements are forcing consumer-packaged goods, food, and beverage companies to manage product information, lot tracking, and related quality standards across their entire supply chain network.

If there ever is a need for a product recall, it must be clone as quickly and as precisely as possible. Reliable, accurate, and up-to-date information is absolutely critical to achieve recall objectives. In addition, as contract manufacturing increases, suppliers are more dependent upon information from their trading partners.

RFID can complement existing MF.S efforts in genealogy tracking. MES, for the most part, is already collecting information such as product ID, time stamp, physical attributes, machine, order numbers, and lot number at each step of the processing.

This information can code onto an RFID tag, pass downstream into the warehouse at a pallet level, and then out into the supply chain, greatly enabling the ability for a manufacturer to retrace steps in a product recall.

Plant asset management

Tagging assets provides information about their location, usability status, maintenance requirements, contents, inventory levels, and so on. Devising production steps, maintenance, and labor schedules based on this information can help increase asset costs, optimize asset performance, and maximize asset utilization.

Tagging reusable assets such as machines, fork trucks, tools, fixtures, and material handling devices is one of the easiest ways for companies to test RFID in a closed loop environment.

By helping reduce downtime and managing scheduled (as well as unscheduled) maintenance more effectively, manufacturing performance parameters such as overall equipment effectiveness (OEE) can improve.

As contract manufacturing becomes increasingly important, visibility into supplier as well as customer activity becomes critical in order to achieve supply chain synchronization. Inventory tracking and visibility relates directly to information management.

The better a manufacturer is able to collect, manage, and use information to drive production assets and processes, the more visibility provided to trading partners.

Depending upon investments in automation and MES, RFID can work on varying scales, either locally or across the entire facility to provide visibility into incoming raw materials, WIR production sequencing, packaging, palletizing, and warehousing operations, as well as final shipping to the next destination in the supply chain.

Labor usage

Bar coding is very common in today's manufacturing environment. However, in many bar coding activities, manual intervention is required for capturing data. An immediate impact of RFID is eliminating those requirements, thereby freeing up labor to perform other, more value-added tasks.

Effective deployment of RFID also has the potential to quickly provide accurate and reliable data that exceeds the bar coding or manual capabilities available. This can have major impact, particularly in high-volume and high-speed manufacturing operations, where speed, accuracy, and timeliness are critical for throughput and performance.

Information management is critical in how RFID-enabled information can link man/machine tasks and gain visibility into labor usage and productivity, setting the stage for redistribution of related tasks and processes.

RFID can dramatically influence critical performance issues like machine performance, line performance, plant performance, and supply chain performance for all manufacturers.

The primary drivers of RFID implementation in manufacturing operations that go well beyond current mandates are more likely to be specific industries such as pharmaceuticals.

The ARC Advisory Group said the pharmaceutical industry possesses the unique attributes most receptive to RFID implementation in the manufacturing supply chain following the rush to fulfill retailer driven mandates.

Regulatory and anti-counterfeiting requirements within the pharmaceutical industry place a premium on accurate and real-time tracking and tracing capabilities to facilitate product recalls to effectively track products across the supply chain.

The U.S. Food and Drug Administration has already recommended RFTD be part of an incremental approach to prevent theft, augmenting other tools such as tamper-proof packaging, bar codes, and hidden inks.

In addition, pharmaceuticals in general have a higher price tag and profit margin on a product basis as compared to typical retail supply chain products. As RFID tag prices continue to fall, pharmaceutical manufacturers will likely lead the drive to begin applying passive RFID tags at a product or item level.
