“…(1): A TFN is denoted simply as (l/m, m/u) or (l, m, u). The parameters l, m and u (l ≤ m ≤ u), respectively, denote the smallest possible value, the most promising value, and the largest possible value that describes a fuzzy event [10,15,16]. While there are various operations on TFNs, only the important operations used in this paper are illustrated (addition and multiplication) [15,16] [15,16].…”
