THE TOPSIS METHOD BASED ON COVERING ROUGH SETS

摘要：

The TOPSIS (technique for order preference by similarity to ideal solution) method has been widely used to rank the preference order of alternatives and determine the optimal choice. In this paper, we firstly give the significant degree of covering in covering rough sets model, and then propose the TOPSIS method based on covering rough sets by combining the significant degree of covering. At the same time, we illustrate the proposed method with a numerical example.
