Abstract:

A decision analysis model based on prior probability dominance relation is proposed to solve multi-attribute decision making problems with preferential and incomplete information. Firstly,in order to avoid the limitations of the extended dominance relation and limited extended dominance relation,the concept of prior probability dominance relation is presented and the rough approximations of knowledge are obtained based on the limitations.Then,compared with the extended dominance relation and limited extended dominance relation,the classification based on the prior probability dominance decision analysis model is more realistic and fits intuitive feeling better. Finally,the example shows the feasibility and effectiveness of the proposed method.

Key words: multi-attribute decision, rough sets, extended dominance relation, limited extended dominance relation, prior probability dominance relation
