By now it seems ancient history, but SAP 's acquisition of Lighthammer in 2005 marked a sea change in attitudes toward integrating plant operations with the business enterprise.
Lighthammer was one of the first software vendors to develop a solution for enterprise manufacturing intelligence (EMI). These solutions aggregate data from diverse plant assets and, once combined with enterprise transactional information, can track key performance indicators (KPI) and support decision-making related to quality, asset management, or other key resources and constraints.
SAP's arch-rival, Oracle Corp. , says it will deliver its EMI product, now called Oracle Manufacturing Hub, “sometime” in 2008.
At the recently held Oracle Manufacturing Summit, the company said the EMI solution will enable these specific actions:
Contextualize plant-floor data and synchronize it with ERP;
Provide real-time intelligence for plant operations; and
Enable a next-generation operations architecture.
While further details about Oracle Manufacturing Hub aren't widely available yet, Alison Smith, a senior analyst with Boston-based AMR Research ,believes Oracle is “well positioned to cash in on its database acumen and enterprise experience. ...Between Oracle Daily Business Intelligence, Sensor Edge Server, Business Intelligence Enterprise Edition, and Fusion SOA middleware components, Oracle already possesses the ingredients needed to bring a comprehensive EMI framework to plants.”
Amit Singh, Oracle director of product strategy, says, “We're leveraging all the technology, pulling it together as a solution, making it extensible. Oracle's advantage is we understand the data model top to bottom.”
The Lighthammer product has evolved into SAP MII—formerly xMII, a composite Manufacturing Integration and Intelligence application.
SAP MII in turn has spawned the emergence of SAP's Perfect Plant initiative—a portfolio ecosystem that takes advantage of partner applications—namely discrete manufacturing execution systems (MES) vendor Visiprise or supply chain execution vendor Acsis —to supply industry-specific plant-floor functionality, thereby freeing SAP from having to develop what from its enterprise perspective must seem niche applications.
Smith says while SAP's foray into the EMI space has been highly visible and successful, SAP MII doesn't cover everything manufacturers will eventually need for demand-driven operations. SAP's solution “is not a substitute for an operational data store or historian, as it does not provide a manufacturing data model or tools for manufacturing master data management,” she says.
Without a data repository, adds Smith, there is “no basis for analytics, root-cause analysis, or discovery techniques like ad hoc correlative analysis and inferential model development.” It's important, she stresses, that manufacturers realize the greatest return on EMI investments may come when they “take an architectural approach that blends… different applications to take full advantage of their respective strengths.”
In many SAP MII installations, a data historian acts as the data store. For example, Dow Corning standardizes across plants with its single instance of SAP ERP and plant use of SAP MII and the OSIsoft PI System data historian. In complex, discrete environments, SAP MES by Visiprise can add that same critical data model component.
“SAP Perfect Plant is a not a product, but a portfolio of products ringed by delivery partners, ISVs, and system integrators,” says Paul Boris, SAP senior director, industry solutions. “We didn't fully realize initially how broad an impact the Lighthammer product would have. But it enables advanced technology to be rolled into the portfolio while leveraging a rich legacy.”
New kid in town
Oracle Manufacturing Hub will connect to plant-floor outputs either through historians or directly.
“It provides linkage, comprehensive data model, rules engine, and connections to higher-level enterprise systems,“ says Singh. “The hub collects, cleanses, aggregates, contextualizes, and normalizes data—which aids in the analytics.”
“Oracle is doing a cool thing by bundling a lot of the critical pieces together,” says Smith. “It is providing a piece of the architecture many are struggling to build on their own.”
At end of day EMI is about understanding how operational decisions impact revenue, earnings, and profitability—i.e., performance management—and how the stated goals of the business enterprise are systematically planned and executed—i.e., production management.
The technology challenges involved in normalizing data to allow apples-to-apples comparisons within a business unit or across sites are considerable. A further question is what metrics or KPIs are truly indicative of performance in the most inclusive sense possible.
“Temperature, speeds, feeds, and flow, without additional information, doesn't mean much to an executive,” says Jim Shaefer, product manager for SAP's MII tool set.
“The master data model is very important at the contextualization level,” says Charles Rieb, VP of product management for process optimization software and services provider AspenTech . “It understands under-the-covers where to get what you're asking for, relating equipment with processes. When you run control data through the model, it's no longer simply temperature, but can be cast as a rate of change”—for example, the beginnings of trend analysis.
Vision comes first
This contextualized information also becomes the medium for exposing data to dashboards or higher-level systems, including EMI and corporate business intelligence systems via Web services typically based on the ISA/95 model. Conversely, the data model is a map for deep-dive drill downs when management wants to get at process details behind aggregated information.
To date, says AMR's Smith, manufacturers are falling short in their efforts to brew enterprise intelligence out of production data.
“Many companies are using the technology in a limited fashion to manage tactical KPIs like OEE and packaging line performance, where it's easiest to calculate ROI,” she says. “To a large extent the technology has outrun the market.”
There are companies that have engineered multi-layered architectures, combining technologies to achieve real business intelligence. Chevron, Saudi Aramco, General Mills, DuPont, and Snap-on Tools are said to be among those involved in such efforts.
Kenosha, Wis.-based Snap-on, for example, “is interested in being able to look at an order spike on Thursday, and determine what steps to take now for when that demand hits the plant next Wednesday,” given current production capacity and constraints among all plants, says Smith.
“Manufacturers need to move from real-time performance KPIs to more of a business intelligence mind-set, what we term 'operational intelligence'—business intelligence thinking converging with real-time data,” Smith asserts. “There's confusion about what's needed,” she adds. “It's architecture—not an application—and the architecture must be built in layers.”
Citrosuco seeks the sweet spot
Citrosuco , headquartered in Matao, Brazil, is one of the world's biggest producers of concentrated and fresh orange juice. At its three plants in Brazil and one in Florida, juice extractors process 100,000 oranges per minute. It's enough for about 2,000 tons of finished products per day.
The company first used Wonderware InTouch in 1998 as its human-machine interface (HMI) for managing automated process equipment. It then brought on additional Wonderware solutions to make greater use of available control data, including Wonderware Historian in 2001.
Wonderware Application Server—now System Platform 3—was brought online in 2003 to improve automation-to-enterprise system integration in conjunction with implementation of SAP ERP.
“Wonderware Application Server allows us to communicate more effectively with SAP from the plant,” says Milton Bilar Montero, senior project engineer. The historian captures real-time data and trends it hourly, passing it through the Application Server/System Platform as reports and SAP information feeds.
Now Citrosuco is piloting Wonderware Information Server, a Web-portal product that will make a wide range of information available on demand to everyone from line operators to plant managers.
“The goal is to look at and compare data from all plants simultaneously,” Montero says. The system should be ready for use by start of the next heavy processing season in June.”
Hexion plants includes corporate in information initiative
Hexion Specialty Chemicals , a Columbus, Ohio-based producer of thermosetting resins and formaldehyde used in bonding, binding, and coating applications, has more than 100 plants around the world. It selected Incuity as its standard for enterprise manufacturing intelligence in 2001.
Incuity provides a common tool for gathering data from a wide mix of disparate data sources assembled by Hexion through acquisitions in recent years. Incuity enables analysis of data independent of the underlying infrastructure, which is then shared through portal or Web browsers; supports building reports and KPI dashboards used in multiple locations; and provides a path to greater enterprise use of data.
Incuity gives production managers new tools to track orders; for R&D labs to monitor product quality and test new resin formulations remotely; and for shipping and inventory to monitor materials. Process engineers can monitor OEE and drill down to resolve issues and optimize processes. The initial facility implementation netted a first-year savings of $300,000, spurring faster ramp-up and multisite rollout.
“The overriding objective for Incuity is to have one corporate-wide implementation accessible in a single portal that can interact with our global SAP system, and that provides powerful analytical tools for process use by staff at local plants,” as indicated by Stephane Lacasse, Hexion IT process systems analyst, and David Holmes, resin process technology manager, in a report.
Hexion is adding an EMI server at its Columbus headquarters so corporate staff can access multisite real-time information and do desktop analytics.
