摘要： 考虑到实际决策问题中损失函数的“多值性”特征，从贝叶斯理论出发，将区间值损失函数引入决策粗糙集，提出区间值决策粗糙集模型。首先，讨论了在贝叶斯期望风险最小的决策语义下，区间值决策粗集理论基本模型的构建过程。其次，分析了区间值决策粗集理论的相关数学性质和准则。最后，通过一个石油投资问题来阐明区间值决策粗糙集模型的应用过程。
关键词: 决策粗糙集理论，概率粗糙集理论，贝叶斯过程，区间值
Abstract: By considering the "multiple-valued" character in practical decision procedure, the interval-valued loss funcdons were induced to decision-theoretic rough set theory (DTRS) based on the 13ayesian decision theory. With respect to the minimum I3ayesian expected risk, a model of interval-valued decision-theoretic rough set theory was built The corresponding propositions and criteria of interval-valued decision-theoretic rough set theory were also analyzed. An example of oil investment was given to illuminate the proposed model in applications.
Key words: Decision-theoretic rough set theory, Probabilistic rough set theory, l3aycsian decision procedure, Interval-valued
