Research on Risk Assessment of Construction Project Construction Phase Based on Interval Numbers and DEMATEL Method

At present, the control of construction project risks is increasingly becoming the key to whether projects can proceed normally. Based on the current research status of risk assessment, this article constructs a risk assessment model for the construction phase of construction projects based on interval numbers and DEMATEL method. This model studies the impact relationship between various risk factors in construction projects, draws a causal relationship diagram, and obtains the key elements of construction project risks. Finally, based on the risk assessment results, feasible suggestions are proposed for better implementation of construction projects.
