An Application of a Preference Restraint Cone DEA Model in Vendor Selection
偏好约束锥DEA模型在供应商选择中的应用

Based on the analysis of measuring criteria for vendor selection under the background of Supply Chain Management, a preference restraint cone DEA model is developed. Comparing with exited methods, the model is more robust without demanding too much and precise information, keeps characteristics of the conventional DEA model, and reflects preference of the decision-maker. Numerical example shows the effectiveness of such model used in vendor selection.
