New features of Wonderware MES 2012 with Quality include automatic data collection as well as enforcement of structured manual sampling plans. A full range of statistical process control charts are offered.
"We already have MES modules that track product transformation steps and collect real-time production data for operations and for performance (overall equipment effectiveness, or OEE)," said Maryanne Steidinger, director, advanced applications, Invensys Operations Management. "Now we've added a module for quality."
The module can collect and track quality data by work order, independently but integrated with the operations and performance modules. All are part of ArchestrA System Platform, Invensys' real-time automation and information management framework, so they use the same methodology.
Monitoring quality data in near real time allows plant operators to respond faster to non-conformance conditions, quality trends and deviations, as well as to take corrective actions that minimize variations and bring quality closer to specifications. It complements existing enterprise quality management systems with sample plan execution automation, higher accuracy in shop-floor quality sample data, integrated statistical process control (SPC) and enhanced work order and operational execution context.
"Data can be collected manually or automatically, online, at the production line, in-line or offline," Steidinger said. "You can apply any of 20 different SPC rules – bar charts, x-bar charts, etc., and integrate the package to the plant floor as well as business systems. You can track quality, consumption and inventory status, tag nonconforming suppliers, and propagate information through the system to wherever it's needed."
A workflow component can enforce procedure and process standardization for consistency and compliance, Steidinger said. "It empowers operators to do a better job – to take those samples, to understand how quality affects production, and to control it."
