Abstract
In this paper, a combined decision-making model is presented for dealing with uncertain and imprecise problems, based on the difference between fuzzy sets and rough sets theories. The model is firstly to classify the uncertain examples given using fuzzy clustering analysis, to make a decision table specified,and then to simplify the decision table by means of the rough sets theory. It gives all possible minimal decision algorithms associated with the decision table. These decision algorithms have found application in larger field.
