CPC 7 Graduate Process ControlSurvey Results

• Some departments require many control courses

• But not many control courses are typically offered from chemical engineering departments!

CPC7 Conclusions

Gatzke Thoughts:• Simulation may not be

sufficient (PCM?)• Need online materials (Virtual

Process Control Book?)• Distance education

(WebCAST?)

• Initial meeting held at CPC concerning online materials

Conclusions

• The number of departments offering graduate control courses is slowly declining in the U.S.

• The job market for the systems area is still healthy, mostly in traditional ChE areas

• Simulation is a critical part of a graduate control course – opportunity for sharing courseware

• Web-based modules can supplement graduate courses – sharing of information to develop virtual textbook

• Distance education could enhance graduate education by sharing expertise and content on specialized topics.

Issues

• Copyright– Usually authors retain copyright, but allow distribution– Creative Commons? Allows for modification.

• Editing and Control– Some want guaranteed level of quality control– Revision and review?

• Time and Motivation– Why write a chapter or clean up notes?

Observations

• Useful resource for new graduate students• Difficult to get contributions

– High load, education on “back burner”?– Many want to “polish” their material

• Various older books available– Other books and chapters that may be useful?

Recent Vision

2007 NSF Engineering Virtual Organization– Gatzke, Hahn, and Parker

• Community driven resources (process control wiki)– Distributed contributions and editing– Reviewers: Not traditional peer review system

• Community news / research / career resource– Community moderated, community generated content– Reviewers: CACHE already exists

• Grow into larger community (CAST 10, etc.)Result: Not recommended for funding, need new vision?

Supported: CACHE effort with multiple industrial participants

Conclusions

We need more content: course notes, book chapter, challenge problems, review articles, presentations, other…

Technology may stay simple for now

Still interested in community driven resource
