A multi-criteria intuitionistic fuzzy group decision making for supplier selection with TOPSIS method
TL;DR: In this study, TOPSIS method combined with intuitionistic fuzzy set is proposed to select appropriate supplier in group decision making environment and Intuitionistic fuzzy weighted averaging (IFWA) operator is utilized to aggregate individual opinions of decision makers for rating the importance of criteria and alternatives.
Journal ArticleDOI
Grey prediction with rolling mechanism for electricity demand forecasting of Turkey
Diyar Akay,Mehmet Atak +1 more
TL;DR: Grey prediction with rolling mechanism (GPRM) approach is proposed to predict the Turkey's total and industrial electricity consumption and results show that proposed approach estimates more accurate results than the results of MAED, and have explicit advantages over extant studies.
Journal ArticleDOI
A biparametric similarity measure on intuitionistic fuzzy sets with applications to pattern recognition
Fatih Emre Boran,Diyar Akay +1 more
TL;DR: A new general type of similarity measure for IFS with two parameters is proposed along with its proofs and it is indicated that the proposed similarity measure does not provide any counter-intuitive cases.
Journal ArticleDOI
Comparison of direct and iterative artificial neural network forecast approaches in multi-periodic time series forecasting
TL;DR: In this study, forecasting was performed using direct and iterative methods, and results of the methods are compared using grey relational analysis to find the method which gives a better result.
Journal ArticleDOI
Interval multiplicative transitivity for consistency, missing values and priority weights of interval fuzzy preference relations
TL;DR: The concept of interval multiplicative transitivity of an interval fuzzy preference relation is introduced and it is shown that, by solving numerical examples, the test of consistency and the weights derived by the simple formulas based on the interval multiplier produce the same results as those of linear programming models proposed by Xu and Chen.
