In the automotive industry and other manufacturing sectors, a final assembly line is responsible for assembling different components of a product in the production system. The productivity of a manufacturing process is determined by its duration, the quantity of workstations employed, and the proficiency of its operators. Therefore, in order to effectively oversee or rival several industrial sectors, or to enhance efficiency in a certain assembly line to uphold productivity. This study details the enhancement process of a four-circuit pressure valve assembly line through the utilization of simulation approaches. This study proposes the utilization of data structure as a means to enhance the efficiency of assembly line operations. The main objectives of this program are to reduce workstation operations and enhance product output, as well as to offer recommendations for optimizing the manufacturing process to attain superior outcomes. The study utilized qualitative methodologies, whereby the procedural sequence was observed and data was gathered in accordance with the data framework specifications. The data structure was built using the collected data, followed by analysis of the results. Subsequently, new simulations were developed, incorporating improvements, to finalize the outputs.
