OVERVIEW

Fuzzy logic, along with artificial neural networks and genetic
algorithms constitutes a part of computational intelligence which, in
recent years, has become a focal point of research. It attempts to
model and mathematically encapsulate the approximate reasoning
processes under the influence of imprecise, incomplete and vague input
data. Fuzzy logic has strengths in modelling highly nonlinear,
complex sytems which are commonly  encountered in product design,
manufacturing and control.

One application of fuzzy logic, control systems utilizing some of its
concepts has become an important engineering tool. This tutorial
presents a comprehensive picture of fundamental issues of fuzzy logic
in order to study the structure and operation of fuzzy logic
controllers.


DETAILED PLAN

The tutorial will address these issues:

        * introduction and approaches to system modeling: comparison
	  of explicit, neural and fuzzy modeling methods,

	* crisp sets and fuzzy sets, basic concepts,

	* operations on fuzzy sets, t-norms and t-conorms,

	* fuzzy relations and composition of fuzzy relations,

	* fuzzy inference, generalized modus ponens, generalized modus 
	  tollens, fuzzy implication functions,

	* a brief look at intelligent control, 

	* fuzzy logic controllers: operation and examples.

Towards the end of the tutorial, a laboratory session is organized. In the 
laboratory session, participants will be able to test their ideas by writing 
their fuzzy rule bases for a simulated fuzzy logic controller in the  UNIX 
environment.


BIO-DATA OF THE PRESENTER

Ahmet Sekercioglu is a researcher at the Laboratory for Concurrent
Computing Systems, Swinburne University of Technology and lecturer at
the School of Electrical Engineering in the same university.  He has
obtained his B.Sc. and M.Sc. degrees from the Middle East Technical
University, Ankara, in 1982 and 1985 respectively. During the M.Sc.
studies he has worked as a research assistant at the Biomedical
Engineering laboratory of Middle East Technical University.  Later, he
has held research and development engineering positions at Aselsan and
Ericsson.  Currently he is working towards his Ph.D. degree in the
domain of Adaptive Fuzzy Systems.

Professor Gregory K. Egan is director of Laboratory for Concurrent
Computing Systems, Swinburne University of Technology and principal
lecturer at the School of Electrical Engineering. He has graduated in
Communication Engineering from RMIT in 1975. He has been awarded an
M.Sc. degree in computational methods in 1976, and, a Ph.D. in
parallel computer architectures in 1979 both at the Victoria
University of Manchester. From 1980 onwards he developed and led the
computer systems engineering groups and developed teaching programs at
RMIT and Swinburne University of Technology.


PREREQUISITES
 
This tutorial will present both introductory and in-depth material.
So, it will be suitable for both to novices, as well as to those with
some background who wish to extend their knowledge in the area of
fuzzy logic controllers. No prerequisite knowledge of the field is
necessary. However, some background in propositional logic and
classical set theory would be helpful.

Examples of structured sequence of tutorials:
--------------------------------------------------------------------------------

There are couple of structured sequence of tutorials that one could adopt.
For example, if the participant is interested in logic/theoretical basis of
AI, then he/she may want to select the following sequence:

Day 1   9.30 - 10.30: Introdution to AI
       11.00 - 12.30: NMR(t)
        2.00 -  3.30: NMR(t)

        2.00 -  3.30: CBR(t) 
        4.00 -  5.30: CBR(p)

Alternatively, if the participant is more interested in the applications of
AI, then the following sequence may be more suitable:

Day 1   9.30 - 10.30: Introdution to AI
       11.00 - 12.30: IDSS(t)
        2.00 -  3.30: IDSS(t)

       11.00 - 12.30: FLFC(t)
        2.00 -  3.30: FLFC(p) 


If the interest is in Machine Learning/Knowledge Acquisition, then the
possible sequence may be:

Day 1   9.30 - 10.30: Introdution to AI 
       11.00 - 12.30: TFML(t)
        2.00 -  3.30: TFML(t)

       11.00 - 12.30: ILDB(t)  or  KAM(t)
        2.00 -  3.30: ILDB(p)  or  KAM(d)

Another possible sequence may be:

Day 1   9.30 - 10.30: Introdution to AI
       11.00 - 12.30: EC(t)
        2.00 -  3.30: EC(t)
        4.00 -  5.30: EC(p)

Day 2   9.00 - 10.30: HS(t)    
       11.00 - 12.30: HS(t)
