Abstract: Aiming at the problem that the experts prefer the different preference information in the process of selecting the scheme, a scheme selection method considering multiple preference information is proposed. The expert can choose a subset from the program set and give the preference information in the form of utility value, preference order, multiplicative preference relations and fuzzy preference relations to evaluate the subset of the program. Transformation functions are used to convert the preference information into the preference vector. According to each expert’s preference vector to aggregate program classification results to feedback and adjust the program subset of every expert. Finally, the multi-stage feedback and adjustment is adopted to improve the group consistency to obtain the optimal scheme. The method is applied to the selection of a vehicle manufacturer’s auto parts remanufacturing scheme, which illustrates the effectiveness of the proposed method.
