Research of Lean Improvement on Oil Pump Production Line in Company D by VSM

Applying the analysis method of VSM, we take the oil pump production line of Company D as the object of study and conduct a detailed analysis of the whole production process to find out the waste generated in the production process, including the problems in transportation, work practices, and production line balance. Using the improvement methods of lean manufacturing and industrial engineering, we proposed improvement plans for value-added time, process flow, and production line balance, and optimized production methods and production layout. After implementing the optimization plan, waste in the production process was effectively reduced, production efficiency was greatly improved, and the overall efficiency of the product line was significantly increased.
