Real-Time Shop Floor Integration: The Right ERP System Can Make It Happen
by Excerpts from a Technical White Paper by IQMS
Production Fall 2008
As a manufacturer, you know where your money is made on the shop floor, day in and day out. And, like countless other manufacturers, you also realize the shop floor is the next great frontier in the quest for truly lean operations. In a recent report entitled Bridging the ERP and Shop Floor Divide, the Aberdeen Group notes that the disconnect between ERP (Enterprise Resource Planning) and the shop floor hinders manufacturing performance. But you already know this. Youve seen it in data collected from the shop floor with pen and paper on spreadsheets and charts, then uploaded in batches or transferred manually to multiple databases that arent readily connected to each other, let alone your ERP system. Very often the data is uploaded after it is needed, creating problematic situations.
In the realm of demand-driven manufacturing, where you must consistently do more with less, real-time information from the shop floor is imperative to prevent problems, drive quality, and enable the flexibility your customers require. Left unchecked, issues like downtime, poor machine performance, scrap, and overruns can quickly erode your profit. But without an enterprise system that works in unison with real-time shop floor data, these issues can remain hidden and change any seeming lean progress into nothing more than a mirage.
Unfortunately, the path to shop floor integration doesnt always appear straightforward. According to Aberdeen, manufacturers face many challenges in eliminating the disconnect between ERP and the shop floor. Existing systems are hard to integrate. Companies have no unifying manufacturing architecture. There are too many applications to support and aging or proprietary systems to consider. Its also difficult to get the right information to the people who need it in time for them to make critical business decisions. Whats more, Aberdeen says effective integration cannot be accomplished simply by collecting shop floor data and passing it on to the ERP. Rather the ERP system must be active in pushing orders to the shop floor. It must keep constant track and provide access to current and planned inventory requirements.
Your shop floor operates in real-time. It moves fast and so must you. Information today about last weeks overrun will not let you prevent the overrun thats about to occur now. Beyond the collection and integration of shop floor data, the real challenge is to make that data actionable in an instant to everyone, at every level within your organization, and in fact across your entire supply chain. Only by doing so will you achieve the visibility and control you need to be competitive in todays demand-driven economy.
Shop Floor Integration Myth v. Reality
Manufacturers approach shop floor integration through various means; some methods are more complicated, and thereby more expensive, than others. A common myth concludes that ERP cannot handle shop floor integration in complex manufacturing environments. As a result, Manufacturing Execution Systems (MES) and more recently Manufacturing Intelligence (MI) dashboard applications have come to the forefront as go betweens, extra layers designed to connect the shop floor to the ERP. Yet in reality, because these bolt-on solutions are not inherent to the ERP system, they require higher levels of customization and architectural changes before they can perform as intended. Once installed, these solutions also may require greater ongoing support from IT staff. And even with the extra cost and effort, they may not provide immediate, accurate, or automated results because they have no execution capabilities, or they rely on batch transfers instead of real-time communication.
Demand-driven manufacturing mandates flexibility to respond automatically to changes in areas such as inventory, production status, customer requests, and even compliance mandates. Batch communication does not happen frequently enough to support this level of flexibility, and worse, batch transfers perpetuate time lags and inaccuracies across your supply chain, resulting in problems such as excess inventory, carrying costs, and lost productivity.
Manufacturers also might believe that the more complex a solution, the better it will be in solving shop floor integration issues. An MES system, for example, may be complex with feature-rich process monitoring tools, but do you need a separate system to monitor process when the machines youre running have extensive process monitors onboard? While an MES system offers information on product properties, that information is not the most relevant to profit. Rather, its your production output that more directly affects your bottom line, and the data derived from that output that is more actionable to your ERP system.
Todays reality also demands real-time communication that flows automatically across your supply chain. A single- database, extended ERP system that knits ERP and shop floor capabilities into one comprehensive weave may deliver better results with less effort and cost than batch-oriented, third-party solutions. For example, an ERP solution like EnterpriseIQ from IQMS can deliver real-time shop floor integration across a globally distributed network and fulfill many of the same functions normally performed by MES systems. EnterpriseIQ with its embedded RealTime Machine Monitoring technology removes the complexity of real-time shop floor integration by using simple contact closures to connect all machines to a single ERP database.
Making Complete Contact
Think of a contact closure as the flip of a switch, up then down for every part produced or even scrapped. By counting these flips as they occur on individual machines, RealTime Machine Monitoring can determine how long it takes to make a part and how many parts are produced in each shift. Because RealTime Machine Monitoring works in tandem with EnterpriseIQ, there is always instantaneous two-way communication between the shop floor and various aspects of the ERP system. EnterpriseIQ pushes schedules to the machines based on demand and RealTime Machine Monitoring automatically provides feedback as production occurs. EnterpriseIQ then manages the complexity of the data by comparing it instantly to predetermined parameters such as average cycle time, scheduled production, inventory on hand, and more to automatically update the finite schedule. Because this information is shared across the ERP, inventory control also is highly incorporated. By recognizing which part or parts the machine made, the communication of raw material, labor, and overhead consumption are compared to the bill of manufacture. The result is to push current and accurate information across your entire supply chain.
Green Means Lean
In Bridging the ERP and Shop Floor Divide, the Aberdeen Group states that best-performing manufacturers are 5 to 15 percent more likely than others to connect individuals at all levels of the enterprise. Even so, Aberdeen states best-performing status also requires total visibility be linked with predictive, real-time, analytic capabilities, and event management. EnterpriseIQ with RealTime Machine Monitoring automatically delivers production information and alerts to any computer or remote device on your network, including cell phones, laptops, and hand-helds, enabling you to respond in real-time from anywhere to prevent problems before they happen.
The system also uses easy-to-read, color-coded LightSticks (See Picture 1.) or an audible enunciator to convey machine performance to those who work on the shop floor. LightSticks allow shop floor operators to quickly identify late, slow, and fast running machines. Machines that are running to standard indicate green or lean status, while machines that are slow light up red. LightSticks glow yellow when a machine is down, and turn blue when a machine is running fast. Stationing computers at every machine on the shop floor can be cost-prohibitive. LightSticks are a cost-effective alternative, and give operators fast, actionable information at a glance.
Real-Time Supply Chain
According to the Aberdeen Group, best-performing manufacturers operate with real-time intelligence that encompasses process, organization, knowledge, and technology. Based on a survey in Aberdeens recent report, these leading manufacturers do a number of things, including: utilize real-time sensing and analytics to proactively avoid schedule interruptions; allow management a real-time view of the shop floor; and make real-time data accessible across the supply chain to include decision makers, operators, customer service, logistics, and delivery.
EnterpriseIQ with RealTime Machine Monitoring enables a real-time supply chain by giving you the tools you need to capture, monitor, manage, and track discrete, cyclical, and continuous operations as they occur. Supply chain automation is supported with capabilities such as activity monitoring and alerts, embedded workflow, label printing, bar coding, automated shift reports, and the ability to correlate shop floor activity automatically to every interaction with customers and suppliers alike, from initiation to resolution.
Reports provide accurate and timely information including good and bad parts, downtime, rejects, and more. Because the data you receive is immediate and in one central location, it provides true power at every point in the production cycle over factors such as labor and supplies, overruns, scrap, quality, and on-time delivery. It also supports adherence to industry standards and quality compliance regulations such as TS13485, ISO 9001 standards, and CFR and FDA requirements.
Summary information can provide a wealth of information for part performance that carries into the schedule or even preventative maintenance, with an overall idea of how well or poorly machines are operating to target standards within an individual work center or across an array of plant operations. (See pictures 2 and 3.) Historical data is used to make the finite schedule and is used to automatically indicate what jobs will run best on what machines based on data such as reject and cycle-time records. Any variances to standard that occur on the shop floor are instantly taken into account, allowing you to leverage advantages such as better-than-average runs, or prevent situations such as having to reset a tool after a job has run.
