Optimizing Vehicle Assembly Line Achievement via Lean Manufacturing: An Evaluation of the Bishoftu Automotive Manufacturing Industry

Vehicle manufacturers nowadays must contend with rising consumer demand and fierce competition for timely delivery of high-quality goods at affordable costs. But the assembly line was not productive at the required rate and capacity due to assembly line delay constraints. However, some workstations in the production line would be delayed. In the assembly line process, from the first to the last workstation, it became starving and blocking at some workstations in the assembly line due to unbalanced assembly workstation. The study aims to Optimizing Vehicle Assembly Line Achievement via Lean Manufacturing: An Evaluation of The Bishoftu Automotive Manufacturing Industry. The study was employed both qualitative and quantitative research approaches. By using those data, the current assembly line was developed with the help of lean manufacturing principles and technique among them methods, value stream map was the most important and the researcher used VSM. The most important wastes were found when the current assembly process then output was examined. Finally, optimized workstation and splitting suggested to the example company after a variety of alternative scenarios, including the current one, were performed to increase the company's production. The findings demonstrated that the first and second scenario increased the case company's bus assembly line output rate. There has been increased line efficiency by 44.65% from 19.25% to 63.9% and also production rate also increased by 0.125 unites.
