| Abstract: | The distribution function is introduced to interval-valued information systems. And the stochastic dominance-based interval-valued information system is proposed. The α-stochastic dominance relation is constructed in inter-valued information system. Theα-stochastic dominance relation is calculated by the Levy distance and some numerical examples are shown for the efficiency of the method. |
