In order to solve the prominent problems such as slowness, subjectivity and inclination of human factors in competitive procurement method selection for general equipment maintenance materials, based on five key indexes including confidentiality, security, number of qualified suppliers, fund saving rate and project time limit, this paper presented a new quantitative model for procurement method selection through fuzzy analytic hierarchy process and optimization ranking of conflicting data. Quantitative calculation can aid fast decision-making on procurement method selection, which is superior to human selection. The establishment of such quantitative model provides a powerful auxiliary tool for decision making with respect to material procurement management.
