Abstract:
One of the main goals in large projects with multiple contractors is to reduce costs in various processes. The complexity of a large project, which is mainly due to the complexity of activities and the existence of interference between different phases and the lack of transparency of activities, can be added to the multiplicity of contractors and the difficulty of proper interface management.As regards that large projects with a large scope of work, have to use several contractors and this issue has a direct impact on increasing project costs, large project management becomes a major challenge that the application of appropriate knowledge, improving processes and skills and tools can play a significant role in its success.In this research, a dynamic model for project management using the system dynamics approach is presented. Also, simulation and testing of model and scenario design and policy including contractor improvement policy selection plan and interface management plan in order to remove the ambiguity of hidden activities to reduce costs and improve project performance have been examined
