Supplier classification of the civil aircraft manufacturing industry based on grey comprehensive cluster of the center triangle winterization weight function

The evaluation on suppliers classification of the large civil aircraft is a complex uncertain decision making problem containing a variety of uncertainties such as randomness, fuzziness, and greyness, etc. This kind of problems is needed to be analyzed and solved effectively, while soft computing tools such as grey system can be useful. In view of this, we construct the CIR model from three-dimension including the competitiveness, increased value rate and relation degree of the suppliers on the manufacture. Then as empirical study the classification on the suppliers of the large aircraft manufacturer based on grey comprehensive cluster of the center triangle whitenization weight function is conducted. Finally, some suggestions and conclusions are given to help implementation of supplier management.
