A new aggregation operator based on mapping and its evaluation application

A new aggregation operator is proposed in this paper, which is defined based on mapping, whose input and output variables can be assigned by several different types of score terms, such as numbers, intervals, linguistic values or symbolic values. First, the definition of the aggregation operator is introduced, followed by the definitions of the layered relationship among the evaluation items with the aggregation operators in order to establish an evaluation system, in which the database technology is involved for better feasibility. Second, the three main algorithms in the evaluation process are described in detail. Finally, the experiment with the logistics-effectiveness evaluation is carried out for validating the effective of the aggregation operator.
