供应商选择的三维动态组合评价方法及应用

The Three-Dimensional Dynamic Combined Evaluation Method and Its Application to Suppliers' Selection

建立了一种供应商选择和评价的动态组合评价模型。在指标权重的确定中以G1法确定主观权重,熵值法确定客观权重。将主、客观方法得到的权重组合集成,避免了单一评价方法易产生的片面性结果;对指标评估值采用动态的分阶段线性组合,充分考虑了被评价对象在不同时期的客观状况对评价结果的影响,弥补了只考虑当前状况易产生的偶然性结果。最后用实例说明了方法的有效性。

A method of Dynamic Constitution Evaluation was suggested. Subjective weight was given based on Glmethod, and objective weight obtained from entropy method. The limitation of the single method had been avoided by combining the objective and subjective weight. Dynamic multi-stages linear constitution was used on evaluating modulus with the fully consideration of the developing condition of the evaluated object during different period. And the practicability of the model was illustrated.
