【摘要】 波兰科学家ZdzisilawPawlak将概率统计中的Bayesian公式与Rough集模型相结合建立基于决策理论的概率模型,给出了一系列的决策规则及相关讨论。在此基础上结合在银行信贷分析的实际例子描述了基于Rough集理论的最小风险决策规则提取方法及它的实际应用,可以看出这为非结构化风险决策问题提供了一条很好的辅助决策的途径。更多还原

【Abstract】 Z. Pawlak discussed the decision rules and relative problems via the combination of Bayesian formula with the model of rough sets, and to establish probability model based on decision theory.By the idea, This paper describes a extracting method of minimum hazard decision rules based on rough set theory. And its applications are illustrated with real examples in bank credit analysis.The method provides a better solving path for non-structure decision problems.更多还原
