Kacprzyk and Stanieski  and Park  were the first to introduce fuzzy mathematics
into inventory management and extend the classical Economic Order Quantity (EOQ) model to the fuzzy inventory model under the condition of ordering cost and holding cost being fuzzy variables.
Since the inception of the fuzzy set theory, Soliman and Mantawy  showed that five major strongly connected branches have been developed, including fuzzy mathematics
, fuzzy logic and artificial intelligence, fuzzy systems, uncertainty and information, and fuzzy decision-making.
The comprehensive evaluation method in fuzzy mathematics
converts qualitative evaluation into quantitative evaluation according to the theory of degree of membership in fuzzy mathematics
, namely fuzzy mathematics
is used to make an overall evaluation of things or objects which are restrained by multiple factors.

The difference between fuzzy analytic hierarchy process (FAHP) and analytic hierarchy process (AHP) is that the former simplifies complex degree of relative importance about judgment target and extends AHP method to fuzzy environment and realizes convenient and fast conversion from qualitative to quantitative about the decision with the aid of fuzzy judgment matrix combining the fuzzy mathematics
and the analytic hierarchy process (AHP).
