What is Triangular Fuzzy Number (TFN)

Handbook of Research on Fuzzy and Rough Set Theory in Organizational Decision Making
A triplet ( m 1 , m 2 , m 3 ) is known as Triangular Fuzzy Number, where “ m 1 ” represents smallest likely value, “m 2 ” the most probable value, and “ m 3 ” the largest possible value of any fuzzy event.

The environmental pressure from various stakeholders, particularly in the selection of green suppliers in the industrial sector, is alarming. The companies are realizing the significance of incorporating green practices in their daily operations. This chapter proposes a framework on the criteria of GSCM practices using MCDM analysis to select green suppliers for an Indian electronics company. The authors have collected the data from a set of 10 available suppliers. The authors use fuzzy AHP and fuzzy TOPSIS approach to rank the suppliers based on the decision makers' preferences on the selection of green suppliers using GSCM practices. The three dominating criteria concluded by the results are the commitment of senior management towards GSCM; product design that incorporates three R's policy for component, materials, and energy; abidance with environmental laws and auditing programs. This chapter carries out a comparison between Fuzzy Analytical Hierarchy Process (FAHP) and Fuzzy TOPSIS method to enhance the quality of decision making and validate the rankings.
