Objective: One of the major challenges in the management of construction projects is the lack of understanding of the mechanisms that cause delays in construction. In the meantime, government infrastructure construction projects have a more complex situation, so that the success in the timely implementation of a construction project within the framework of government laws is one of the biggest goals and concerns of managers and agents involved in these types of projects.
Methodology: It can be the present study identifies the mechanisms of project time delay risks based on system dynamics in order to identify and evaluate policies for the timely implementation of construction projects. For this purpose, first the literature and background were examined and during the semi-structured interview with the participants of the research, the effective factors on the timely implementation of the Iranian government construction project were identified. In the continuation of the dynamic model of the timely implementation of the Anrani project, the simulation was carried out using the data of the infrastructure operation project of the first section of Mobarakeh railway, Sefidasht, Shahrekord.
Conclusion: After validation; According to the results of the sensitivity analysis of the system dynamics model, the exploitation policies during the construction project were identified in three strategies of providing project financial resources, project planning and control, and accountability of the project beneficiaries. In the following, it was also designed and applied to the model with selected combined policies. comparing the behavior of key model
