Simulation Research on Success Factors of Megaprojects Based on SD Model
To achieve safe operation and sustainable development of megaprojects,the success factors of megaprojects are simulated and studied using system dynamics.Firstly,the success factors of megaprojects was identified and their index system was constructed.Secondly,the interactions among the success factors and construct the SD model of the success factors of mega-projects were analyzed.Finally,taking the Hong Kong-Zhuhai-Macao Bridge as an example,the simulation was conducted u-sing Vensim software and sensitivity analysis was performed on 12 constant-type success factors.The results show that increased investment and control in cognitive-emotional,executive leadership,behavioral relationships,resource integration,and organi-zational learning promote megaproject success and the factors that have a significant impact on megaproject success are mega-project management experience,financial redundancy,application of digital technology,and behavioral inertia.This expands the study of the success factors of megaprojects and provides a theoretical basis for promoting the success of megaprojects.
