Optimización de la productividad mediante la aplicación de herramientas LEAN Manufacturing en la línea de producción de pantalones deportivos en la Empresa Casa YOLY Multifabritex.

Abstract

The objective of this research was to optimize the production process in the production line of sports trousers through the implementation of Lean Manufacturing tools in the CASA YOLY Multifabritex Company. The methodology focused on the study of the production cycle of the sports trousers, by identifying the current production process, initializing with the socialization, collection and reception of the company´s information. Later, the design of tools with a Lean approach was developed. Manufacturing for the optimization of productive processes, according to the diagnosis and assessment of the initial state in the production line, both the VSM, process analysis diagram, route diagram complied with the 5’S parameters, and the percentage of the productivity. Finally, the feasibility was evaluated through a pilot test in the company, as par of the application process, with the comparison between the initial state of the company and the current state according to the indicators: productivity, 5’S methodology, material transportation distance, in addition to the application distance, in addition to the application of the paired T test, which allowed the analysis of the variable comparing the initial state and the implemented methodology. As a result, distances were reduced, improving the route with 109 meters during the process, where distances in transferring the raw material are short and the movements of the workers are necessary, improving productivity by 0,4329 trousers/hour, that is, an increase of 6 units to the current workday, validating the alternative hypothesis to improve the company’s productivity. It is concluded that the implementation of VSM and 5’S increased the optimization percentages with an average of 74% defined as very good. Periodic audits of the Lean Manufacturing tools implemented are recommended.
