Abstract

The study proposes a schedule optimization management framework for warehouse construction project clusters, driven by the goal of enhancing the efficiency and quality of the engineering delivery process. With the rapid expansion trend in modern enterprises' business activities, warehouse construction projects not only grow rapidly in scale but also increase in complexity, raising the requirements for accurate project management, especially in time planning precision. The cutting-edge project management tool, Critical Chain Method, has demonstrated significant advantages in managing uncertainty factors and resolving resource allocation conflicts in multi-project parallel processing. By implementing the Critical Chain Method in a warehouse construction project of an enterprise in Shandong Province, this study observed a significant reduction in the actual completion cycle compared to the scheduled plan. This not only improved the likelihood of completing the project on schedule but also effectively reduced both total time limit and cost. The results validate that the proposed schedule optimization strategy is scientifically sound and effective in practical project management.
