中文摘要：
多粒度粗糙集理论为多源决策信息系统的规则提取提供一种有效的方法，而如何对决策规则集进行评价是利用规则进行合理准确的决策和对未知样本进行可靠预测的关键问题之一．针对已有规则性能评价指标的不足，提出整体确定性、整体协调性、整体支持度的3类整体决策性能评价指标．这些评价指标将为更多的决策问题求解提供一定的理论依据．
英文摘要：
The muhigranulation rough set theory is proved to be an effective method for extracting decision rules from the multi-source decision information systems. However, how to evaluate the decision rules is one of the key problems to find reasonable and accurate decision rules and predict an unknown sample in terms of decision rules. In this paper, according to the disadvantage of the existing evaluation measures of rule performance, the whole certainty measure, the whole consistency measure, and the whole support measure are proposed. These evaluation measures will be helpful for the solution of some decision problems.
