Optimization of motorcycle assembly processes based on lean manufacturing tools
(Springer, 2020) Quezada Cazorla, Jonnathan David; Sigüenza Guzmán, Lorena Catalina; Llivisaca Villazhañay, Juan Carlos
Global competition and economic dynamism force the assembly industry to look for productive philosophies of improvement, optimizing processes, and resources. The challenge in the optimization process involves finding tools that will grant an optimal process. This article proposes a process optimization through the application of Lean Manufacturing tools, with the necessary guidelines analyzed and verified by computational simulation in a motorcycle assembler. Firstly, applying a plant distribution, together with the change of productive system, allowed the reduction of distances, elimination of unnecessary movements, and reprocessing. Then, Pull System reduced the stock of both the product in process and the final product in the warehouse, avoiding the generation of future waste and expenses due to overproduction. Finally, the use of the 5S tool entailed maintaining order and cleanliness inside the plant to facilitate the management of internal resources. In the study reported, an average reduction of 40% in assembly time and an average increase in production of 30% of all motorcycle models that were part of the study are achieved.

Competition and economic dynamism force the assembly industries to look for productive philosophies of improvement, optimizing processes, and resources. The challenge in the optimization involves which tools to be applied will grant an optimal process. The present work proposes the optimization of processes, taking as a case study a motorcycle assembly company, through the application of Lean Manufacturing (LM) tools and additional concepts such as: 1.- Plant distribution, which together with the change of the productive system of work cells to assembly line, allows the reduction of distances traveled, elimination of unnecessary movements and reprocessing; 2.- Pull System, which achieves a reduction in stock of both product in process and final product in the warehouse, avoiding the generation of future waste (silent in LM) and expenses for overproduction; and 3.- 5S tool, which entails maintaining order and cleanliness inside the plant to facilitate the management of internal resources. The main results of this study are an average reduction of 40% in assembly time and an average increase in production of 30% of all motorcycle models.
