Abstract: In order to reduce time and cost in engineering design, such as
gate design, integral field knowledge must be obtained effciently.
After studying ID3 and its improved methods ,a new
algorithm (Fuzzy ID3) and its main concept are presented to
overcome some disadvantage in classical ID3 algorithms. In its
application of gate design, fuzzy knowledge gotten by the new
algorithm is more efficient than the knowledge by other ID3
algorithms, the set of fuzzy knowledge is much smaller than that
of knowledge by classical ID3 algorithms. On the other hand, fuzzy
knowledge represents field data more naturally to the way of
human thinking and more robust in tolerating
imprecise, conflicting and missing information.
Key words: Gate
