Implementation of a Lean Manufacturing and SLP based system for a footwear companyAbstract
La presente investigación se basa en el trabajo realizado por los autores Munive Silvestre Sergio; y Páucar Chaicha Victor denominada: “Implementación de un Sistema basado en Lean Manufacturing y SLP para una empresa de calzado”. Es importante mencionar que el artículo se encuentra debidamente citado e insertado en las referencias del documento. El siguiente artículo abarca uno de los principales problemas en el sector de calzado que es el incumplimiento de pedidos. El incremento de productos defectuosos está vinculado a la falta de capacitación del personal, lo que genera productos no aptos para la venta. El excesivo consumo de tiempo en movimiento de personal y material sugiere que existe una deficiente distribución de planta, por lo tanto, disminuye su productividad de producción. Finalmente, los retrasos en el proceso de producción se relacionan con que los procesos no están optimizados, por lo que se incurre a una cantidad de tiempo obsoleto durante las actividades de los procesos de fabricación. Para enfrentar este problema, se desarrolló una propuesta enfocada en el uso del Lean Manufacturing como SLP (Systematic Layout Planning) y Andon, a fin de aumentar la productividad de la empresa, optimizar y agilizar los procesos de producción. Para validar la efectividad de la propuesta, se utilizó un sistema de simulación que permitió determinar un nuevo escenario donde se obtuvo una disminución del indicador de productos defectuosos en 3.13% y una mejora de la productividad en 38%, esto corrobora un incremento en la cantidad de pedidos atendidos.This research is based on the investigation developed by the authors Munive Silvestre Sergio Enrique; and Paucar Chaicha Victor David called: “Implementation of a Lean Manufacturing and SLP based system for a footwear company” that allowed increase in the number of orders enhances company sales and profits and to meet the customer demand at the right time. The present study is based on the research, conducted by authors Sergio Munive and Victor Paucar, called "Implementation of a Lean Manufacturing and SLP based system for a footwear Company in Peru" which consisted of addressing one of the main problems of the footwear industry, namely the high rate of order non-compliance. The main causes of this problem are the increased rate of defective products, delays in the production process, and excessive time consumption in the movement of personnel and materials. The increase in defective products is associated with a lack of adequate training, resulting in goods unsuitable for sale. Excessive time consumption in the movement of staff and materials suggests poor plant distribution, which affects productivity. Finally, delays in the production process imply that processes are sub-optimal, resulting in inefficient time use over the manufacturing process. To face this issue, a proposal is focused on the use of Lean Manufacturing, such as Systematic Design Planning (SLP) and Andon, was developed to increase productivity, as well as optimize and streamline production processes, considering Covid-19-related safety protocols. To validate the effectiveness of the proposal, an ARENA simulation system was used to establish a new scenario where the defective product indicator is decreased by 3.13% and productivity is improved by about 38%. In turn, the resulting increase in the number of orders enhances company sales and profits also to meet the customer demand at the right time
