Mejora de los procesos productivos en la línea de cocinas y hornos mediante Lean Manufacturing en la Empresa “Lincoln” de la ciudad de Riobamba

Abstract

The objective of this project was to improve manufacturing processes in the production line of kitchens and ovens through lean manufacturing in the company “Lincoln” in the city of Riobamba. For this purpose, lean manufacturing tools such as VSM (process analysis), 5'S (order and cleanliness of work areas), Kanban (production control), time recording and diagrams were used to learn about the process of obtaining industrial ovens and stoves. To do this, it began with the collection of data through interviews and visits to the company, with this information was developed the data needed for the study and the solution in the areas studied, through this information was designed a system of cards (the red card in the production areas of ovens and kitchens, to improve control in production, the yellow card allowed to establish a verification process to avoid losses or downtime, the green card helped with inventory control), this system of cards when are placed on the Kanban board, allowed the production manager and employees developed a better plan process, so that everyone knew which processes were being performed or which process was about to be performed and to take action on them. This allowed us to reduce production costs with a saving of $27.13/ oven and 27.14/kitchen; according the time production we have an improvement in ovens of 0.45 days/oven and 0.44 days/kitchen in kitchens. The lean manufacturing tools allowed the optimization of time and eliminated certain wastes that were generated in human resources, as well as in production time. It is recommended that annually the company Lincoln performs a diagnosis of its production processes.
