A System Dynamics Approach for Sensitivity Analysis of BIM Technology Application Risk

The application scope of BIM technology in the engineering field is gradually expanding, but the risk of BIM technology cannot be ignored. Based on the literature review, this paper analyzes the risk factors of BIM technology and constructs a system dynamics model of BIM technology application risk including the aspects of BIM operation environment, organizational cognition, technology investment, and application environment. Through the sensitivity analysis of exogenous variables, which are regarded as the decisive role in the system as a whole, it is determined that BIM operational environment risk and organizational cognitive risk are easily affected by the change of risk value of risk factors, and the risk factors of the accuracy of data, the complexity of BIM software operation, the unclear ownership of data and the imperfect contract system have a significant impact on BIM application risk.
