Özet:
The challenges in project management are to deliver projects faster, better, and cheaper. One of the major problems in construction that affects the success of the project is the delays. Unprecise project schedule and inefficient resource management can lead to project delays and cost overruns very easy. Another problem in construction is an excessive amount of waste. The Line of Balance (LOB) method is advantageous over other scheduling techniques in repetitive projects because it maintains work continuity and minimizes working team idle time. Value Stream Mapping (VSM) is a lean construction tool, which visualizes and optimizes the processes in the projects by eliminating waste and producing continuous flow. Although both tools LOB and VSM are proved to be powerful tools, limited research was focused on combining the features of the tools. The objective of this study is to create a model to optimize the project duration scheduled with the LOB technique with the help of VSM. The model is tested in a high-rise building project built-in Ankara. VSM future state was used to optimize the occurred delay in the project and to eliminate the non-value-adding activities in the concrete operations. The future state of the schedule was proposed by utilizing the data provided by the experts and showed faster delivery times. Since LOB is a resource-driven technique, the remaining activities were optimized using resource optimization method. A resource optimization model for resource-leveling and allocation that guarantees the optimal solution was presented. The model used in this study could help construction professionals in reducing waste by implementing lean concepts for a better sustainable future.
