Abstract:

A DWAForce operator facing combined evaluation is built based on the density weighted aggregation operator. The DWAForce operator extends the idea of discriminating rewards and punishment used for combined evaluation and carries out unrestricted adjusting on discriminating rewards and punishment by the control of the parameter, which improves the flexibility of this method. Furthermore, the DWAForce operator has many good qualities.It can also deals with the point and vector arguments, and possesses the aggregation structure of combined optimization evaluation values or order values. Finally, a numerical example is given to testify the effectiveness and  some novel characteristics of the DWAForce operator.
