The process of eliciting and aggregating experts opinions becomes very important in many application fields. It plays a crucial role for getting relevant information and making decision. Usually, experts prefer to give their opinions qualitatively using natural language. For making decision, these qualitative opinions are generally transformed into quantitative beliefs, in order to combine them using evidence theory. The major drawback of this transformation process is the possibility of modification or even lost of information. Dealing with this problem, we propose in this paper, to avoid this transformation process by combining qualitatively experts preferences using qualitative conjunctive and disjunctive rules of combination.
