Objective To investigate the feasibility of grey relational analysis method in hospital material supplier selection and evaluation. Methods A hospital material supplier selection and evaluation system was established with three dimensions and indexes. Grey relational analysis method was used to construct the index array, the optimum and worst arrays as well as the evaluation function. Some examples were taken for verification. Results Six suppliers were evaluated retrospectively, and then sorted by merit. Conclosion Grey relational analysis method is feasible, simple and reliable for the selection and evaluation of hospital material supplier.
