Tested and proven strategy to develop optimal automated process
fault analyzers

Process fault analyzers monitor process operations in order to
identify the underlying causes of operational problems. Several
diagnostic strategies exist for automating process fault analysis;
however, automated fault analysis is still not widely used within
the processing industries due to problems of cost and performance
as well as the difficulty of modeling process behavior at needed
levels of detail.

In response, this book presents the method of minimal evidence
(MOME), a model-based diagnostic strategy that facilitates the
development and implementation of optimal automated process fault
analyzers. MOME was created at the University of Delaware by the
researchers who developed the FALCON system, a real-time, online
process fault analyzer. The authors demonstrate how MOME is used to
diagnose single and multiple fault situations, determine the
strategic placement of process sensors, and distribute fault
analyzers within large processing systems.

Optimal Automated Process Fault Analysis begins by
exploring the need to automate process fault analysis. Next, the
book examines:

* Logic of model-based reasoning as used in MOME

* MOME logic for performing single and multiple fault
diagnoses

* Fuzzy logic algorithms for automating MOME

* Distributing process fault analyzers throughout large
processing systems

* Virtual SPC analysis and its use in FALCONEER(TM) IV

* Process state transition logic and its use in FALCONEER(TM)
IV

The book concludes with a summary of the lessons learned by
employing FALCONEER(TM) IV in actual process applications,
including the benefits of "intelligent supervision" of process
operations.

With this book as their guide, readers have a powerful new tool
for ensuring the safety and reliability of any chemical processing
system.
