Density Weighted Averaging Middle Operator

Aiming at the condition that existing information aggregation operators neglect the density degree of attribute information distribution, the theories and a method of one-dimensional clustering are introduced in the work. On the basis of above theories, the density weighted averaging (DWA) middle operator is developed. Composite operators composed of the DWA and other five existing operators give attention to manifold operators' characteristics. A final example is used to testify some novel characteristics of the DWA and composite operators
