A dissertation submitted to the Faculty of Engineering, University of the
Witwatersrand, in fulfilment of the requirements of the degree of Master of Science
Engineering / A framework designed to contain and manage the use of knowledge in a real-time
knowledge based system for high level control of an industrial process is
presented.
A prototype of the framework is designed and implemented on a static objectorientated
shell. Knowledge is stored in objects and in forward chaining rules.
The knowledge has a well defined structure, making it easy to create and manage.
Rules are used to recognize conditions and propose control objectives. The
framework uses the knowledge to determine variables that if altered will meet the
objectives. Control actions are then found to implement changes to these variables
The use of explicit control objectives makes it possible to determine if an action
worked as intended and if its use is suitable for the present conditions. This
enables a learning mechanism to be applied in the expert system.
The prototype operated adequately, but the knowledge required to drive the.
system was found to be very detailed and awkward to create. / Andrew Chakane 2018
