Multi-level fuzzy synthesis evaluation on construction supply chain risk

Due to the fuzziness of construction supply chain risk, a two-level fuzzy synthesis evaluation model, based on the object of construction supply chain of raw materials in cascade hydropower plants along Yalong River, has been developed using related fuzzy mathematics theories in this paper. Furthermore, the application of entropy method in determining the weight minimizes artificial errors, leading to a fairer way to compute the weight. Finally such a model is employed in real applications to demonstrate its feasibility in the evaluation of construction supply chain risk.
