Ranking of Bangladeshi Coals Based on Fuzzy Set Theory
نویسندگان
چکیده
This study develops a computational framework for ranking Bangladeshi coals for industrial use based on fuzzy set theory. The ranking process considers coal quality parameters (known as selection or ranking criteria) such as sulphur content (ultimate analysis), fixed carbon, volatile matter, moisture content, and ash content (proximate analysis) and calorific value. The selection criteria are fuzzified according to expert’s opinion and the ranges prescribed in literature. Fuzzy sets are employed to recognize the importance of the selection criteria. Finally, Yager’s fuzzy multi-criteria decision-making approach with min-max aggregator is employed to get the best-ranked coal. Based on the proposed methodology, a software system is developed to facilitate the decision-making process.

متن کاملA Proposed Preference Index For Ranking Fuzzy Numbers Based On $alpha$-Optimistic Values
In this paper, we propose a novel method for ranking a set of fuzzy numbers. In this method a preference index is proposed based on $alpha$-optimistic values of a fuzzy number. We propose a new ranking method by adopting a level of credit in the ordering procedure. Then, we investigate some desirable properties of the proposed ranking method.

The intuitionistic fuzzy set has been applied to game theory very rarely since it was introduced by Atanassov in 1983. The aim of this paper is to develop an effective methodology for solving matrix games with payoffs of Atanassov’s triangular intuitionistic fuzzy numbers (TIFNs). In this methodology, the concepts and ranking order relations of Atanassov’s TIFNs are defined. A pair of bi-object...
