Description
Summary:Nowadays, external factors such as increasing levels of competition and having a permanent place in the market are directing companies to use their systems more efficiently, to reduce their costs, and to produce higher quality products. Process improvement steps are important in studies of these companies. In this study, the vacuum test station that created a bottleneck was determined by analyzing the production process in an exploratory way. Through exploratory data analysis, it was possible to perform an initial data investigation to discover patterns, spot anomalies, test hypothesis, and check assumptions with the help of summary statistics and graphic representations. By determining the value-added test time of the vacuum test station, the process time was reduced. Using the new test period, production capacity increased and a more efficient operation of the line was achieved. The number of daily production increased from 136 to 188, line efficiency increased from 55% to 77%, and the stations waiting for each other decreased from 35% to 10%. At the same time, the annual production capacity of the line increased by 27%, reaching from 58K to 79K.
