A new method of ascertaining Attribute Weight based on discernibility matrix

Attribute Weight Determining (AWD) for multi-attribute evaluation and decision-making is a hot and difficult problem. According to the existing weight method based on rough sets having some deficiencies, A new measurement attribute importance and attribute weight determining methods are proposed on the basis of the literature review, which is discernibility matrix-based methods to determine the weight matrix. The method takes into account the has considered can handle nuclear for empty decision table, and can guarantee all the weights of attributes are not for zero, an example shows that the method is effective and correct‥
