Abstract：In view of the selection of medical equipment suppliers, the evaluation index system of
medical equipment supplier selection was constructed in this paper. The improved rough set theory was
used to reduce the attributes of supplier selection, and the objective weight was obtained. Then, the
subjective weight was obtained by using the analytic hierarchy process. The organic combination of
subjective and objective weight made it more scientific to evaluate the alternative supplier. This method
could help more hospitals to make a reasonable decision.
