“…Since then, FREs based on various compositions have been investigated. Some commonly compositions include max-min [4,5,12,18,30,32,40], max-product [3,23,25,26,31,36], max-Archimedean t-norm [22,34,37], max-t-norm [29,33] and maxarithmetic mean [16,35] compositions. Di Nola et al [8] indicated that if the solvability of max-continuous t-norm FREs is assumed, then the solution set for the FREs can be fully determined from a unique greatest solution and all minimal solutions, and the number of minimal solutions is always finite (see also [6,12]).…”
