Approximation of fuzzy numbers by convolution method huan huang a congxin wu b adepartment of mathematics, jimei university, xiamen 361021, china bdepartment of mathematics, harbin institute of technology, harbin 150001, china abstract in this paper we consider how to use the convolution method to construct ap. In social network analysis, relational structures play a crucial role in the processing of complex data this paper proposes a fuzzy relational structure which consists of a non-empty universal set and a set of fuzzy relations of finite arity.
In function optimization, fitness approximation is a method for decreasing the number of fitness function evaluations to reach a target solution it belongs to the general class of evolutionary computation or artificial evolution methodologies. Fuzzy logic can be used in any decision making process such as signal processing or data analysis an example of this is a fuzzy logic system that analyzes a power system and diagnoses any harmonic disturbance issues. Fuzzy logic is an approach to computing based on degrees of truth rather than the usual true or false (1 or 0) boolean logic on which the modern computer is based. As a consequence, fuzzy system applications can be found in many fields of human activity, especially in control tasks of nonlinear and complex systems, where expert knowledge in the form of fuzzy rules is known.
The fuzzy approximation operators may be also composed by a family of crisp approximation operators, from which the definition of the pair of lower and upper fuzzy rough approximation operators defined in our previous paper is simplified in axiomatic approach, fuzzy approximation operators can be characterized by axioms. This paper presents a general framework for the study of rough fuzzy sets in which fuzzy sets are approximated in a crisp approximation space by the constructive approach, a pair of lower and upper generalized rough fuzzy approximation operators is first defined the rough fuzzy approximation. Fuzzy domains and their linear membership functions will eventually allow to achieve a rather high-resolution i/o function between crisp input and output variables. Fuzzy vogel’s approximation method algorithm 1 balance the given transshipment problem if either (total supply total demand) or (total supply total demand) 2 for each row of the fuzzy transshipment table identify the smallest and the next to.
Fuzzy approximation-based adaptive backstepping optimal control for a class of nonlinear discrete-time systems with dead-zone abstract: in this paper, an adaptive fuzzy optimal control design is addressed for a class of unknown nonlinear discrete-time systems.

Fuzzy transportation problem (ftp) is the problem of minimizing fuzzy valued  serdar korukoglu and serkan balli, an improved vogel’s approximation method for the transportation problem, mathematical and computational applications, article in press (2010. I would hesitate to use the term function approximation in this context if i follow your question correctly, the objective is map a non-linear function into another domain via fuzzy methods to do so, you first need to define your fuzzy set membership functions. Fuzzy logic examples using matlab consider a very simple example: we need to control the speed of a motor by changing the input voltage when a set point.
Theorem 213 (varma and john (a)) let ( , ) be a multi-fuzzy approximation space and let ℐ be an implicator satisfying the law of importation then for the ℐ− lower multi-fuzzy approximation operator ℐ of. Rough type-2 fuzzy approximation operators based on the equivalence relation on characterization of rough type-2 fuzzy sets in particular, there is a question of possibility of the solution of this task of the dot data displaying dependence of some output size on two independent arguments by the cut-glue approximation method. This article investigates the rough approximation of a fuzzy concept on a probabilistic approximation space over two universes we first present the definition of a lower and upper approximation of a fuzzy set with respect to a probabilistic approximation space over two universes by defining the conditional probability of a fuzzy event. In this research, three approximation methods are used in the new generalized uniform fuzzy partition to solve the system of differential equations (sodes) based on fuzzy transform (fzt) new representations of basic functions are proposed based on the new types of a uniform fuzzy partition and a.

Nearest piecewise linear approximation of fuzzy numbers lucian coroianu1, marek gagolewski2,3, przemyslaw grzegorzewski2,3, abstract the problem of the nearest approximation of fuzzy numbers by piecewise lin. Taking into account that interval-valued fuzzy numbers can provide more flexibility to represent the imprecise information and interval-valued trapezoidal fuzzy numbers are widely used in practice, this paper devotes to seek an approximation operator that produces an interval-valued trapezoidal fuzzy number which is the nearest one to the given interval-valued fuzzy number, and the.
