Abstract: Considering multidimensional cloud can describe complex fuzzy concept, a multiple attribute evaluation method based on multidimensional cloud model was proposed. The concept of "attribute conceptualizing" was introduced and each attribute was described using on}dimension cloud. Then, the multidimensional judging clouds of comments and the multidimensional attribute cloud of system were established. The evaluation result was achieved by comparing the similarity degree between the two kinds of cloud models. The experimental results show that this method can realize multiclassification and ranking and reflect the influence of each attribute on the synthetical evaluation result clearly.

Key words: Multidimensional cloud model, Normal cloud model, Multiple attribute evaluation
