Point of View %E"v@

l Information is the meaningful interpretation and correlation of Zu<S<??Jf

l The use of a hammer to insert screws, although partly effective, c%bzrYQvA;

Justification T--%UZD]W  
l We choose the so called xx in our experiment because it has HOF=qE*p  
received wide acceptance and can I!Z"X&  
l Prolog was chosen because it offers a well known and flexible ~@)s)K  
environment in which fuzzy reasoning may be easily implemented. 9e c},~(  
l The rationale behind this is that it can be much easier for an 1D3 8T  
estimator to rate a cost as high than to attempt to place a dollar 0AdxV?6z  
value on the estimate. Y9>92#aME  
l This strategy has been widely used in fuzzy control applications x(xi%?G  
since it is natural and easy to implement. Z1:%Aq xP  
l A function definition expresses the membership function of a GmaNi  
fuzzy set in a functional form, typically a bell-shaped function, etc. qTN%9!0@9  
Such functions are used in FLC because they lead themselves to F>3 o0ke}  
manipulation through the use of fuzzy arithmetic. RGs7Hc  
l It should be noted that in our daily life most of the information on |q 8N$m  
which our decisions are based is linguistic rather than numerical in 1DhC,)+D}q  
nature. Seen in this perspective, fuzzy control rules provide a natural vV*J;%MO  
framework for the characterization of human behavior and decisions 9cUa@;*1  
analysis. 5 7t.Ud  
l Many experts have found that fuzzy control rules provide a '"\'<>Be  
11YJ W-V  
convenient way to express their domain knowledge. This explains VgODv  
why most FLCs are based on the knowledge and experience which DyCzRkH  
are expressed in the language of fuzzy "if-the" rule. jx}'M$TA
