|Real-Time Shop Floor Integration: The Right ERP System Can Make It Happen|

|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. You’ve 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 aren’t 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 doesn’t 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. It’s also difficult to get the right information to the people who need it in time for them to make critical business decisions. What’s 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 week’s overrun will not let you prevent the overrun that’s 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 today’s demand-driven economy.
Shop Floor Integration – Myth v. Reality
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 you’re 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, it’s 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.
Today’s 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
Green Means Lean
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
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.
A Single Conclusion
EnterpriseIQ with RealTime Machine Monitoring is designed from the ground up to support 24/7, real-time shop floor integration in today’s demand-driven, manufacturing environments. A single-source solution, EnterpriseIQ is written, developed, and supported by IQMS to deliver a wealth of functionality with simplified vendor contact. IQMS applies this same principle to its RealTime technology, using the simplicity of signal data and the comprehensive accessibility of one database to deliver tangible results and complete shop floor visibility within an easy-to-manage and user-friendly computing environment.
