Tóm tắt

Construction project delay has been reported as a significant cause of the project’s failure, which results in cost overrun, thereby decreasing the effectiveness of the project. Therefore, project management has placed much effort in construction works’ scheduling to enhance project performance. However, construction schedule has been commonly addressed within traditional methods that rely on project managers’ subjective experiences and manually-performed approaches, resulting in time-consuming and inaccurate decision-making. This study is thus aimed to handle these limitations. Using analyses of the Grey Wolf Optimizer (GWO) model, inspired by the leadership hierarchy and hunting mechanism of grey wolves in nature, this study supports reducing the construction time and minimizing the additional construction cost. Furthermore, another computational tool, namely Solver-addins, is also used to verify the reliability of the result. The findings of this study will provide a valuable tool for supporting construction management to deliver projects on time, improving construction project performance
