GT Advanced Technologies Announces the Release of Acuity Performance Management Software

"Over the past several years, PV manufacturers have made significant investments in our DSS crystalline growth systems," said Vikram Singh, GT's vice president and general manager of its PV equipment group. "These manufacturers are being driven to lower their cost of manufacturing to remain competitive. Understanding how their DSS equipment assets perform is a critical step toward achieving this goal. Acuity software is an innovative and powerful application that puts real-time production data into the hands of production managers. Acuity software turns this data into information that manufacturers can use to improve production efficiency and lower the cost of their crystal growth operations."

Acuity software allows manufacturers to establish key performance indicators (KPIs) that are most critical to achieving optimal performance of their DSS assets. DSS Acuity performance software offers a wide range of features such as configurable KPI dashboards, historical trend analytics, remote monitoring of alarm data, detailed run-to-run performance data and recipe management.
