THE EVOLUTION OF AN ONLINE MODEL-BASED OPTIMIZATION SYSTEM - IT OFFERS A VALUABLE TOOL FOR PROCESS DESIGN

The evolution of an on-line, model-based optimization system began wit h the development of steady-state simulators for specific processes. I t proceeded through development of general purpose steady-state simula tors with data reconciliation and optimization capabilities. This syst em, with interfaces to millwide information or data highway systems, e xecutive software, displays and printers, can provide new and powerful tools for on-line optimization. Further developments to provide dynam ic simulation, dynamic data reconciliation and performance attributes are now underway to improve performance and substantially widen the ar eas of application.
