Quantified trapezoidal fuzzy numbers [PDF]
Journal of Intelligent & Fuzzy Systems, 2017 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.

Penalty method for fuzzy linear programming with trapezoidal numbers [PDF]
Yugoslav Journal of Operations Research, 2009 In this paper we shall propose an algorithm for solving fuzzy linear programming problems with trapezoidal numbers using a penalty method. We will transform the problem of maximizing a function having trapezoidal fuzzy number values under some ...

A New Distance Measure for Trapezoidal Fuzzy Numbers [PDF]
Mathematical Problems in Engineering, 2013 We propose a new distance measure for the space of all trapezoidal fuzzy numbers using centroid point and left/right spread of trapezoidal fuzzy numbers. Moreover, the metric properties of suggested distance measure are investigated. Indeed, we show that for two arbitrary trapezoidal fuzzy numbers if the distance between centroid points and also the ...

Fuzzy Regression Analysis using Trapezoidal Fuzzy Numbers
Industrial Engineering & Management Systems, 2020 © 2020 KIIE As a widely used method, regression analysis plays an increasingly important role in creating statistical models and making forecasts in the field of economics and finance. The use of traditional regression for modeling socio-economic processes is not sufficiently substantiated in some situations.

The Inverse and General Inverse of Trapezoidal Fuzzy Numbers with Modified Elementary Row Operations
MathematicsTrapezoidal positive/negative fuzzy numbers have no single definition; instead, various authors define them in relation to different concepts. This means that arithmetic operations for trapezoidal fuzzy numbers also differ. For the operations of addition,

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. However, these similarity functions have drawback for specific situations.
