- Abstract:
- In the three-way decision-theoretic fuzzy rough set model, several scholars established the objective function based on the similarity three-way decision-theoretic fuzzy rough set model to derive the method for calculating the optimal threshold pair (α, β). However, during this research, the authors did not discuss the description of the decision costs in the similarity three-way decision-theoretic fuzzy rough set model. The new function describing the decision costs is used in the method for calculating the threshold pair (α, β) based on the fuzzy information system. First, in the fuzzy information system, the fuzzy number is associated with the decision costs of three-way decisions by establishing a function describing the decision costs. Then, the numerical description of the decision costs of three-way decisions is obtained by fitting the membership frequency. Finally, two examples are given to illustrate the feasibility and applicability of the method.
