Construction of a fuzzy membership function based on interval number

An approach based on interval number for constructing a fuzzy membership function considering some problems existing in statistical methods was proposed.The conception of the youth using interval number was described,the interval number was transformed into a limited boundary fuzzy figure based on the knowledge of interval number and fuzzy number,and then a α-cut set of a normal fuzzy number was obtained by weighted computing extending it into a fuzzy membership function.Experimental results showed that this approach was simple and accurate with wide applicability and the fuzzy membership function was more continuous,objective and suitable to people's subjective consciousness.
