Justification VV?+q)  
l We choose the so called xx in our experiment because it has O<iE,PN)  
received wide acceptance and can 6peO9]Zy  
l Prolog was chosen because it offers a well known and flexible R7x4v  
environment in which fuzzy reasoning may be easily implemented. u+[ZWhKUp  
l The rationale behind this is that it can be much easier for an }3lM+]pf  
estimator to rate a cost as high than to attempt to place a dollar x~j%  
value on the estimate. Cg}cD.  
l This strategy has been widely used in fuzzy control applications l K}('7\  
since it is natural and easy to implement. D>?%p"e  
l A function definition expresses the membership function of a zJ3{!E}`v  
fuzzy set in a functional form, typically a bell-shaped function, etc. f*1.Vg0`-  
Such functions are used in FLC because they lead themselves to K$ #(\-M  
manipulation through the use of fuzzy arithmetic. ["MF-tQ5  
l It should be noted that in our daily life most of the information on yF l@ z  
which our decisions are based is linguistic rather than numerical in 3UslVj1u  
nature. Seen in this perspective, fuzzy control rules provide a natural L:XnW 1(Or  
framework for the characterization of human behavior and decisions fk#SD "iJ

l Many experts have found that fuzzy control rules provide a nI|jUD +y

convenient way to express their domain knowledge. This explains #)GL%{Oa
