Abstract :
In this paper, we introduce the fuzzy interval number to decision-theoretic rough sets (DTRS), and propose a novel three-way decision model of fuzzy interval decision-theoretic rough sets (FIDTRS). The fuzzy interval number is used to describe the uncertainty of loss functions in DTRS. The corresponding propositions and criteria of FIDTRS are analyzed. An illustrative example of mines management is given to illuminate the proposed model in applications.
