Abstract：The multigranulation 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.
