Abstract: For the multi-attribute decision-making problem with preference information on alternative，in which the attribute weights are known incompletely，this paper proposes a new decision method.After solving the optimal problem of minimizing the maximum deviation between the subjective and objective preference，the vector of attribute weights are reasonably determined.The method can overcome the drawback that there is no guarantee that the deviations between the subjective and objective preference for each alternative are all minimized in the existing methods.Finally，the applied example of product development proves that the approach is feasible and practicable.
