If m≤keE≤m+1, m ＜ n, then obfuscation error amount ME is the k through rounding upeE；
If keE ＜-n, then obfuscation error amount ME is-n；
If keE ＞ n, then obfuscation error amount ME is n；
If m≤kecE≤m+1, m ＜ n, then obfuscation error change value MEC are the k through rounding upecE；
If kecE ＜-n, then obfuscation error change value MEC are-n；
If kecE ＞ n, then obfuscation error change value MEC are n；
Knowledge base includes data base and rule base,
Depositing the fuzzy membership vector value of input, output variable in data base, this vector value is that input, output are through correspondence The set of corresponding value after the discretizations such as domain, if corresponding domain continuous print, then can be as membership function, for defeated The fuzzy variable entered, membership function is stored in data base, provides data to inference machine in fuzzy reasoning relation.
