l Information is the meaningful interpretation and correlation of =ily=j"hK

Justification ?gH[la  
l We choose the so called xx in our experiment because it has \pmS*Dt  
received wide acceptance and can J<) qw  
l Prolog was chosen because it offers a well known and flexible v.0qE}' |  
environment in which fuzzy reasoning may be easily implemented. g \mE  
l The rationale behind this is that it can be much easier for an nt.LiM/L  
estimator to rate a cost as high than to attempt to place a dollar oXPA<ef o  
value on the estimate. 2YD\KXDo  
l This strategy has been widely used in fuzzy control applications [KDxB>R<{  
since it is natural and easy to implement. FD=% 4#|  
l A function definition expresses the membership function of a k"wQ9=HP7  
fuzzy set in a functional form, typically a bell-shaped function, etc. Q|y }mC/  
Such functions are used in FLC because they lead themselves to d;i|s[6ds`  
manipulation through the use of fuzzy arithmetic. 7ZcF0h  
l It should be noted that in our daily life most of the information on WQ| :TLQ  
which our decisions are based is linguistic rather than numerical in $8EEtr,!  
nature. Seen in this perspective, fuzzy control rules provide a natural CH++3i2&  
framework for the characterization of human behavior and decisions ep >!jMhJa  
analysis. K_Y-N!h  
l Many experts have found that fuzzy control rules provide a #2Rz=QI  
}F08o,`?  
convenient way to express their domain knowledge. This explains C6+ 5G-Z  
why most FLCs are based on the knowledge and experience which u@a){ A(P
