Efficient production

Stringent requirements on safety, traceability and quality were important factors to take into consideration when Westinghouse Electric Sweden decided to modernize its entire manufacturing system, including the support systems. Prevas' expertise in MES (Manufacturing Execution Systems, the layer between business information systems and manufacturing) and Wonderware was decisive.

Maria Kolli, Head of IT at Westinghouse, explains.
"Prevas has a high level of expertise and experience in this area, which was a deciding factor for us. It was important to us to have a solution that complied with the ISA-95 standard, so this also influenced our choice of development partner," she says.

Quality monitoring is an important function in the new MES platform. Roger Keller, is a project manager at Prevas who has prior Wonderware experience. He says,
"The quality function alone was a comprehensive subproject. For this work, we created a framework for quality monitoring that covered everything from order processing to the operator involved in production, and back to the business information system again. Now it is possible to discover quality issues and address them much quicker than before, when production data was collected and dealt with manually afterwards," he says.
