Selecting Supplier of Cluster Supply Chain Based on Fuzzy Measurement

Uncertainty in operation process of cluster supply chain raises the issue of flexibility, where the supply lead-time and demand quantity are the two most common changes occurring in cluster supply chain. Focusing on the flexibility of cluster supply chain, the fuzzy set theory was applied to give the representation for the variables, and model the cluster supply chain flexibility. Besides it, a supplier selection method was developed. Finally, an illustrative example was given for demonstration.
