Transformation Linear Membership Function by Using the Modified S- Curve [PDF]
المجلة العراقية للعلوم الاحصائية, 2011 In this paper, we concentrate on two cases of fuzzy linear programming problems (FLPP): LPP with coefficient of objective function and coefficient of available resources and constraint are trapezoidal and triangular of fuzzy numbers respectively.

International Journal of Computational Intelligence Systems, 2016 In this paper, the researcher proposed a method to cardinal, median value, variance and covariance of exponential fuzzy numbers with shape function . The covariance used in this method is obtained from the exponential trapezoidal fuzzy number, first by ...

Near Fixed Point Theorems in the Space of Fuzzy Numbers
Mathematics, 2018 The fuzzy numbers are fuzzy sets owning some elegant mathematical structures. The space consisting of all fuzzy numbers cannot form a vector space because it lacks the concept of the additive inverse element.

A signed distance for (γ,δ) interval-valued fuzzy numbers to solve multi objective assignment problems with fuzzy parameters [PDF]
International Journal of Research in Industrial Engineering, 2022 In this paper, a multi-objective assignment problem with fuzzy parameters (FMOASP) is introduced. These fuzzy parameters are characterized by an interval-valued fuzzy numbers instead of fuzzy numbers.

Ranking fuzzy numbers using preference ratio: A utility function approach [PDF]
Decision Science Letters, 2013 Ranking fuzzy numbers is one of the most important phases in any decision making process in fuzzy environments. In most cases, we deal with fuzzy numbers in the field of evaluating alternatives with fuzzy information or linguistic variables.

Representation of uncertain multichannel digital signal spaces and study of pattern recognition based on metrics and difference values on fuzzy n-cell number spaces [PDF]
, 2009 In this paper, we discuss the problem of characterization for uncertain multichannel digital signal spaces, propose using fuzzy n-cell number space to represent uncertain n-channel digital signal space, and put forward a method of constructing such fuzzy

Fuzzy Semi-Numbers and Their Elementary Arithmetic With a Medical Case Study
International Journal of Computational Intelligence Systems, 2018 A new methodology for processing non-normal fuzzy sets is proposed. To break the predominant constraint on normality of fuzzy numbers the concept of fuzzy semi-numbers is introduced Then it is shown how to generalize operations defined on fuzzy numbers ...

Classification of Complex Fuzzy Numbers and Fuzzy Inner Products [PDF]
, 2020 The paper is concerned with complex fuzzy numbers and complex fuzzy inner product spaces. In the classical complex number set, a complex number can be expressed using the Cartesian form or polar form. Both expressions are needed because one expression is
