The gray clustering decision of technical risk of large-scale complex construction engineering design

摘要

The large-scale complex construction engineering design is a complicated system engineering. It is difficult to determine or quantitate the evaluation index and the attribute value of the project technical risk, making the technology risk analysis and evaluation become the bottleneck of engineering risk management. In view of the grayness and hard-quantitation of the technical risk, this paper proposes a comprehensive evaluation method of construction engineering design technical risk, combined with analytic hierarchy process (AHP) and gray clustering decision. By using this new method, the paper analyses and assesses the technical risk of three general construction scheme of a large-scale complex construction project.
