Abstract :
A rough membership function in the incomplete information systems is introduced. We also define the concept of a rough membership function in a incomplete decision table. It is a generalization of the classical rough membership function of Pawlak rough sets. Some basic properties of the measure are examined, and two examples are illustrated for the use of the measure.
