The initial reason for this thesis is the desire of Sansera to reach their target production with this production line. They already invest on conveyors to carry part with more reliability between workstations which has led to an under than expected production increase. To achieve the target production this thesis does a simulation study by developing a virtual model of the production line which is a powerful tool to identify weak point and potential areas for improvement.Through an iterative process of model improvement and analysis, various weaknesses in the production line are identified and addressed, leading to the proposal of different solutions. The study focuses on two key approaches for improving production efficiency, which can be valuable for decision-making purposes. However, the conclusions drawn from these improvements are subject to scrutiny due to the quality and accuracy of the underlying data. The validity of the results depends on the data collected and the assumptions made during the modeling process.In conclusion, this study demonstrates the effectiveness of simulation modeling in optimizing production processes and identifying potential areas for improvement. It highlights the importance of data quality and methodology in drawing reliable conclusions.
