Justification \@N~{72:k  
l We choose the so called xx in our experiment because it has A*81}P_  
received wide acceptance and can }HmkTk  
l Prolog was chosen because it offers a well known and flexible YZSQOLN{  
environment in which fuzzy reasoning may be easily implemented. o$+R  
l The rationale behind this is that it can be much easier for an r Dlu&  
estimator to rate a cost as high than to attempt to place a dollar UntFkoO  
value on the estimate. a7F_{Mm  
l This strategy has been widely used in fuzzy control applications Jvsy 6R  
since it is natural and easy to implement. ^" 54Q^SH  
l A function definition expresses the membership function of a r^<,f[yH  
fuzzy set in a functional form, typically a bell-shaped function, etc. V\{@c%xW  
Such functions are used in FLC because they lead themselves to ~O PBZ#  
manipulation through the use of fuzzy arithmetic. !t"/w6X1I  
l It should be noted that in our daily life most of the information on t&=bW<6  
which our decisions are based is linguistic rather than numerical in .KC V|x;QW  
nature. Seen in this perspective, fuzzy control rules provide a natural +_cigxpTc  
framework for the characterization of human behavior and decisions V:J|shRo  
analysis. Us'JMZ~  
l Many experts have found that fuzzy control rules provide a Ax;?~v4Z  
etiUt~W  
convenient way to express their domain knowledge. This explains vN],9 q  
why most FLCs are based on the knowledge and experience which 3'`&D/n  
are expressed in the language of fuzzy "if-the" rule. f77W{T4
