TopQuadrant © Copyright 2001 -2005 TopQuadrant Inc., “Semantic Technology and EA”, slide 32 Operations End of the Life-cycle – Semantic Command and Control Environment (SCCE) screenshots from Sherrill-Lubinski’s SL-GMS The Launch Controller (LC) looks for weather and ice conditions that can affect the checkout for launch, using a high-level summary-level dashboard, called the ICE display. A condition occurs in the fueling operations and LC asks an engineer in the firing room to look into fuelling operations. The Firing Room Engineer (FRE) has a more detailed view of the fueling operation and notices some alarm messages on the hypergolic flows. FRE asks a Hydraulics Engineer to monitor a dashboard of the Fuel Tank. The Hydraulics Engineer switches to a more detail view of the hypergolic fluids supplies and discovers a leaking valve problem.
