RETRACTED: Approximation of fuzzy complex numbers by the form x ˜ + i y ˜
Journal of Intelligent & Fuzzy Systems, 2022It plays an important role in the calculation of fuzzy numbers using some special fuzzy numbers to approximate general fuzzy numbers in fuzzy analysis, similar to fuzzy complex analysis.

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 1998
As the number of parameters involved in an economic model is often uncertain, we propose that it be estimated using fuzzy numbers. Since we move in an environment of uncertainty, it is logical to leave room for deviation in estimating membership functions.

Trapezoidal approximation-preserving the fuzziness of a fuzzy number
2012 9th International Conference on Fuzzy Systems and Knowledge Discovery, 2012Fuzziness is an important index to capture the relevant information about the fuzzy number's ill-defined magnitude. In this paper, we propose a new trapezoidal approximation of an arbitrary fuzzy number, which preserves its fuzziness. Some properties of translation invariance, scale invariance, preservation of expected value, width and fuzziness of ...

Approximations of Fuzzy Numbers by 2-2-step Type Fuzzy Numbers
2021 2nd International Conference on Artificial Intelligence and Information Systems, 2021In this paper, an approximation method is given using step type fuzzy number to approximate a general fuzzy number. Say concretely, for any given general fuzzy number, a group of calculation formulas are obtained for the coordinates of the left end point of the left step and the right end point of the right step of the 2-2-step type fuzzy number that ...

Approximation of intuitionistic fuzzy numbers by trapezoidal intuitionistic fuzzy numbers
Journal of Intelligent & Fuzzy Systems, 2017The notation of extended intuitionistic fuzzy number is introduced and the representation of the weighted extended trapezoidal intuitionistic approximation of an intuitionistic fuzzy number is given in this paper. The problem related to aggregation is addressed about approximating the given intuitionistic fuzzy numbers or aggregating the given ...

Approximation of Parabolic Fuzzy Numbers
2017Most of the real world problems are complex that is raised from uncertainity in the form of ambiguity. To overcome the ambiguity and impreciseness, Zadeh [20] introduced fuzzy set theory in the year 1965. The underlying power of fuzzy sets is that linguistic variables can be used rather than quantitative variables to represent imprecise concepts which ...
