Interval-Valued Intuitionistic Fuzzy Inference System for Supporting Corporate Financial Decisions

Abstract: Representing the inherent uncertainty in the corporate financial environment is critical for effective decisionmaking in this domain. This is attributed to the increasing complexity of such an environment. One way in which to address this issue is to represent financial attributes in terms of intervalvalued intuitionistic fuzzy sets. In this paper, a novel intervalvalued intuitionistic fuzzy inference system (IVIFIS) of the Takagi-Sugeno-Kang type is proposed. To calculate the output of the IVIFIS system, a de… Show more

“…For developing this kind of system, the Mamdani-type FIS are widely used [52,53]. Fuzzy decision support systems are used in different knowledge areas such as Medicine [53,54,55,56,57], Agriculture [58,59], Financial [60,61,62,63,64], Construction [65], Education [66], and more.…”

“…The authors only used three components of a triangular intuitionistic fuzzy number which these components are used to determine. Hajek and Olej [17] investigated an interval-valued intuitionistic fuzzy inference system that is similar to the Takagi-Sugeno-Kang type system. The authors proposed a defuzzification method to obtain a crisp output from the evaluated system.…”

“…The authors used the difference between the membership function and non-membership function as the weights of the defuzzification methods. In the aforementioned studies [8][9][10][11][12][13][14][15][16][17]21,22], scientists preferred using weighted-averaging-based defuzzification methods. In actual applications, the authors chose different weights, such as membership values, non-membership values, hesitancy values, accuracy values, the difference between sides of (α − β) cuts, and possibility values.…”

“…The fuzzification unit determines the membership degree for the numerical values of all n variables of the vector X to the corresponding input LTs of the considered fuzzy system [30]. The fuzzy inference engine, in turn, based on fuzzified signals and data received from the rule base, sequentially performs aggregation, activation and accumulation operations [31]. The rule base consists of a set of rules composed of defined antecedents and consequents.…”
