About Fuzzy system

Fuzzy system, server months I always consider it as a contraller which using in wash machine, vehicle, or other contral machine. but actully, fuzzy is an paradigm of computing. where computing can use, fuzzy can use too.
 
So, about computing, when we want to model an object, we will consider the object as computing which with input and output. And in fuzzy theory, zadeh and other scientists who also devote to fuzzy theory have define some operate with maths tools. such as fuzzy number, fuzzy relation, and fuzzy logic. all of them are begin with fuzzy set theory which proposed by zadeh.
 
Hereafter, we know that the fuzzy is a mothod of uncertainty in modeling. thus, I remaind a sentence saying by zadeh, that is ‘uncertainty is an attribute of information’. however, we always focus on information technology, according the previous knowledge, we should deal with information with uncertainty paradigm. and fuzzy is one of the method of uncertainty. now, to construct uncertainty, scientists have found out a lot of ways, such as Cloud, rough set and so on.
 
But I focus on fuzzy and begin with fuzzy in research unertainty modeling.
