In the thesis, we have examined three options for manufacturing a light module. The first option is manual production, which leads to a higher number of complaints due to a greater risk of not meeting quality requirements. To avoid this, we can hire an additional worker to check the quality or automate the process, ensuring a high level of quality assurance. The product under investigation consists of 6 parts, so an investment in 6 machines would represent a high initial cost. The company is interested in determining which of these manufacturing options is the most cost-effective and at what production volume the investment in automation pays off. We have demonstrated the investment justification using static and dynamic methods, cost comparisons, and the breakeven point.
We have proven that the investment does not pay off in the case of producing 130,000 units per year within the given time frame. However, if additional projects are accepted and the production volume increases to 250,000 units annually, the investment in automation becomes justified, as the costs of manual labour with an additional worker are too high. The company would need to receive a higher number of orders for an extended period to compare the costs of automation with those of manual production with an additional worker, which is the most efficient method of manufacturing.
