摘要：
In the previous decision-theoretic rough sets (DTRS), its loss function values are constant. This paper extends the constant values of loss functions to a more realistic dynamic environment. Considering the dynamic change of loss functions in DTRS with the time, an extension of DTRS, dynamic decision-theoretic rough sets (DDTRS) is proposed in this paper. An empirical study of climate policy making validates the reasonability and effectiveness of the proposed model.
