Elasticity Evaluation of Modern construction supply chain Based on Interval Intuitionistic Fuzzy Numbers

In order to improve the operation efficiency of modern building supply chain, this paper combines interval intuitionistic fuzzy numbers to evaluate the flexibility of modern building supply chain. In order to accurately express the precise preference information of decision-makers for decision-making schemes, this paper uses interval form to better reflect the essential characteristics of the problem, and describes the essential attributes of the construction supply chain (CSC) in detail. Moreover, this paper constructs the general dynamic network model of CSC and the index system of robustness factors of CSC, and takes a construction company project as an example, organizes an expert evaluation team to evaluate the safety of CSC risks. The results show that the improved method proposed in this paper is feasible, and the evaluation results are in line with the actual situation, which solves the uncertainty problem of construction project SC risk evaluation well, broadens the application fields of interval intuitionistic fuzzy number, and provides a theoretical basis for the safety prevention of construction project supply chain.
