Lean Manufacturing tools applied to the metalworking industry in Perú

Small and medium-sized enterprises often rely heavily on their production process to position themselves in the market. However, there are few situations where companies have the knowledge and financial resources to improve their operational performance. This study proposes the use of the tools of the Lean Manufacturing philosophy to reduce most activities that do not add value within the production process. First, the diagnosis of the current situation of the company under study was carried out, as well as the determination of the impact caused by the problems encountered. Secondly, the design of the solution proposal was proposed using 5S, SMED and SLP to mitigate the causes of the previously diagnosed problems. Finally, in the simulation, the production system and the changes proposed obtained a reduction in the lead time, due to the reduction of the unproductive times identified, of 6.79%.
