Abstract
Fuzzy set theory was developed by Dr. Zadeh in America in order to treat some fuzzy problems in human decision or thinking and so on.
In this paper, fuzzy set theory is applied on corrosion test data as follows;
(1) fuzzy IF-THEN rules is made depending on corrosion data by veteran engineer and some engineering information,
(2) membership functions of IF-part and THEN-part are specified,
(3) through fuzzy inference calculation, some predictions of corrosion data are expected.
Results of fuzzy inference method are compared with real data of corrosion, and similarity to both data may be recognized.
