This bachelor’s thesis focuses on the optimization of buffer stocks on the final assembly line at Toyota Motor Manufacturing Czech Republic s. r. o. (TMMCZ). This work transforms the existing intuitive approach to buffer management into a precise methodology based on the analysis of real process data. The theoretical section defines the principles of lean manufacturing, Little’s Law, and the role of variability in the production flow. The analytical section utilizes a statistical evaluation of historical downtime data, with the 90th percentile of variability set as the key parameter for capacity sizing. Based on these calculations, an optimal vehicle fill level is proposed for all monitored buffers. The proposal also includes a process standard for production ramp ups and shift changes, which utilizes the asymmetric run-out of lines to achieve the target state.
