Solutions of interval type-2 fuzzy polynomials using a new ranking method

Numerical methods for solving fuzzy equations: A survey

“…In [49], a new ranking technique is proposed which overcomes the drawback of the ranking fuzzy numbers technique proposed in [48]. The ranking technique proposed in [49] has four parameters named value, ambiguity, fuzziness, and vagueness.…”

“…In [49], a new ranking technique is proposed which overcomes the drawback of the ranking fuzzy numbers technique proposed in [48]. The ranking technique proposed in [49] has four parameters named value, ambiguity, fuzziness, and vagueness. With the new parameter vagueness, the process of fuzzy polynomials in generating real roots is more effective and precise.…”

“…The proposed technique in [49] is successfully applied in the interval type-2 fuzzy polynomials, interval type-2 fuzzy polynomial equations, dual fuzzy polynomial equations as well as system of fuzzy polynomials.…”

“…3 and Y e (Y I ) into(49) the resulting equation is valid.Example 3.5.2. Suppose [A 1 ] = (1, 2, 3), [A 2 ] = (−3, −2, −1) and [A 3 ] = (3, 4, 5).…”
