In the dynamic and complex field of construction management, the ability to accurately predict and manage the impacts of various types of delays on construction schedules is crucial. This paper presents an innovative, user-interactive simulation model developed using the advanced simulation software, AnyLogic. The model is designed to provide a comprehensive framework for understanding and analyzing the dynamics of construction projects, with a particular focus on the impacts of different types of delays. The model incorporates diverse patterns of construction schedules, reflecting the complex nature of real-world construction projects. These delays will act as stress factors that are divided into three categories, which are Site-wide, Activity-type and Specific-activity delays. Each of these delay types has a unique impact on the construction schedule, adding a layer of complexity to the simulation and providing a more accurate understanding of project dynamics. A significant feature of this model is its user-friendly interface. This interface allows users to input the types of delays they anticipate in their projects, along with their probable impacts. By incorporating this user input, the model can predict the impact of these delays on any given project. This interactive feature not only enhances the versatility of the model but also makes it a practical tool for project management. Through the development and application of this model, this paper aims to provide valuable insights into how different delay types can affect the overall construction schedule. Furthermore, this paper proposes strategies to mitigate the impacts of these delays, thereby enhancing project efficiency and resilience.
