Herramientas de manufactura esbelta para el mejoramiento de la productividad en la fábrica de peluches Lily Toy´s

Abstract

This research work proposes the improvement of productivity through lean manufacturing tools application proposal, for which a current situation of company analysis is carried out through methods study use, time study and VSM, determining that existing production plant waste are unnecessary movements, material transport, waiting, defective products and unnecessary processes, which generates low productivity at company. A study was carried out based on bibliographic and field research through which a descriptive matrix was established in which the possible causes of waste and lean manufacturing tools that can reduce or eliminate them in each area are placed, also the weighted factors method was used for tools selection and it was found that the 5'S, Kaizen, Jidoka and TPM are the best option. After tools identification, a productivity improvement plan was proposed and the procedure to be followed for each tool was described in manuals. In the case of the 5'S, resources in production plant were classified and ordered, in the case of Kaizen the work methods were improved and activities that do not add value to the product were eliminated, in the case of Jidoka and TPM manuals were established to help in the correct implementation. Through the simulation of the current and proposed situation, it was possible to present the improvement of the weekly production capacity of the medium sized piglet by 27.84% and the improvement of the delivery time of a batch of the final product by 37.07%, therefore, the improvement of productivity.
