Similarity Measure between Exponential Trapezoidal Fuzzy Numbers with Metric Distance Method [PDF]
, 2018 In this paper, we define the metric distance between two exponential trapezoidal fuzzy numbers and we use this metric for similarity measure. The basic properties of the above-mentioned similarity measure are proved in detail.

Franklin OpenIn the real world, we are faced with many problems that cannot be easily described by crisp values, as there is always some uncertainty involved in real-life situations and in those situations, we end up receiving fuzzy values rather than crisp ones in ...

A new similarity function for generalized trapezoidal fuzzy numbers [PDF]
, 2013 Numerous authors have proposed functions to quantify the degree of similarity between two fuzzy numbers using various descriptive parameters, such as the geometric distance, the distance between the centers of gravity or the perimeter.

Advances in Fuzzy Systems, 2011 Ranking fuzzy numbers are an important aspect of decision making in a fuzzy environment. Since their inception in 1965, many authors have proposed different methods for ranking fuzzy numbers. However, there is no method which gives a satisfactory result

Quantified trapezoidal fuzzy numbers
The aim of this work is to construct quantified trapezoidal fuzzy numbers as an extension of trapezoidal fuzzy numbers, by using modal intervals and accepting the possibility that the α-cuts of a trapezoidal fuzzy number may also be improper intervals ...

Cybernetics and Information Technologies, 2015 In this paper we investigate the dynamic multi-attribute group decision making problems, in which all the attribute values are provided by multiple decision makers at different periods. In order to increase the level of overall satisfaction for the final

Representing fuzzy numbers for fuzzy calculus [PDF]
In this paper we illustrate the LU representation of fuzzy numbers and present an LU-fuzzy calculator, in order to explain the use of the LU-fuzzy model and to show the advantage of the parametrization. The model can be applied either in the level-cut or

Determination of Reorder Point in Fuzzy Sense [PDF]
Muṭāli̒āt-i Mudīriyyat-i Ṣan̒atī, 2004 One of the most important issues in inventory control is determination of the recorder point. Are usually in forms of crisp or probability. In this article the parameters are considered as fuzzy numbers because of ambiguities in the real world.

Adapted gradient algorithm for algebraic fuzzy neural networks
, 2002 : A learning algorithm based on a gradient technique is introduced for the algebraic fuzzy neural network with fuzzy weights. The fuzzy weights can be triangular fuzzy numbers (usually nonsymmetric), or trapezoidal fuzzy numbers.
