Group decision making in medical system: An intuitionistic fuzzy soft set approach

Fault-tolerant enhanced bijective soft set with applications

“…Recently, it has been combined with theories, such as fuzzy set [2][3][4][5], rough set [6], algebras [7,8], group [9,10], ideal [11], topology [12] and intuitionistic fuzzy soft sets [13]. Moreover, soft set theory has been applied in areas, such as parameters reduction [14][15][16], decision making [17][18][19][20], risk assessment [21], medical diagnosis [22][23][24], group decision [25].…”

Uncertain linguistic fuzzy soft sets and their applications in group decision making

“…The advantage of soft set is that it is free from the inadequacy of the parameterization tools, such as the probability theory, fuzzy sets and rough sets [1,4]. Recently, with these developments of soft set theory, kinds of applications have been studied, such as decision making [4][5][6][33][34][35][36], engineering [7], economics [8] and medical science [9], and so on. The meanings of kinds of soft sets are dealing with different practical issues based on vagueness and uncertainties.…”

Comparative Study of Type-1 Fuzzy Logic and Type-2 Fuzzy Logic

“…Fuzzy determination mechanism (FDM) incorporates the fuzzy inference, fuzzy implication, and the fuzzy aggregation. Das and Kar [10] have proposed the use of fuzzy soft approaches for designing diagnosis algorithms. The algorithm involves analyzing the considerations of a group of experts who give their opinion only regarding the symptoms they have knowledge about.…”

“…Using (8), the Type-2 FL based rule aggregation values are computed for the two consequences and are later defuzzified to get the probability. f) Defuzzification: Using the centroid method as stated in (10), the final probability is calculated. Here, w (i) is the weight of aggregated fired rules for a consequence, i = [0, 1].…”
