Application of GC-TOPSIS Method in the Process of Supplier Evaluation

The job of supplier evaluation becomes the key of the manufacturing enterprises to improve competitiveness in networked manufacturing. A method of weight calculation for the supplier evaluation criteria is introduced in this article entropy method. The paper combines Gray Correlation method and TOPSIS method and forms GC-TOPSIS method. The method reflects the closeness between ideal program and actual program about Euclidean distance and gray correlation degree separately from the distance and shape similarity, so the method has a characteristic of dual-baseline. Finally through an example, this evaluation method is shown feasible.
