Ranking of trapezoidal intuitionistic fuzzy numbers
2012 12th International Conference on Intelligent Systems Design and Applications (ISDA), 2012Techniques for ranking simple fuzzy numbers are abundant in nature. However, we lack effective methods for ranking intuitionistic fuzzy numbers(IFN). The aim of this paper is to introduce a new ranking procedure for trapezoidal intuitionistic fuzzy number(TRIFN). To serve the purpose, the value and ambiguity index of TRIFNs have been defined.

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 ...

BOUNDED LINEAR PROGRAMS WITH TRAPEZOIDAL FUZZY NUMBERS
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2010Recently Ganesan and Veeramani introduced a new approach for solving a kind of linear programming problems involving symmetric trapezoidal fuzzy numbers without converting them to the crisp linear programming problems. But their approach is not efficient for situations in which some or all variables are restricted to lie within fuzzy lower and fuzzy ...

A New Algorithm for Ranking of Trapezoidal Fuzzy Numbers
International Journal of Fuzzy Systems, 2018Fuzzy numbers are used to represent numerical quantities in a vague environment since the measurements are imprecise in nature in this environment. Ranking fuzzy numbers is then an important issue for decision-making problems in a fuzzy environment.

The median for a trapezoidal fuzzy number
Microelectronics Reliability, 1994Abstract In the case where a trapezoidal fuzzy number is adopted as fuzzy data in the fuzzy problem, the representative ordinary number has been proposed as an average and applied in various fields of problems. In this study, the median of the trapezoidal fuzzy number is proposed besides the representative ordinary number and explained by several ...
