Mejora de la productividad mediante la aplicación de la teoría de restricciones en la manufactura de puertas de garaje forjadas, caso de estudio: Microempresa Industrias Metálicas Vilema (IMEV)

Abstract

This reseacch was intended to apply The Restricction Theory to improve the forge garaje door manufactury productivity in the Metal Industry Vilema. In this study aim, data colleting was carried out at first trough the manufacturing process timekeeping and the direct observation technique for the process diagram plotting as well as the aplication of the Aggregate Value Analysis methodology in order to determine no profit activities into the forge garage door manufacturing process. The initial information, showed not only the average time required for the forge garege door prodution, which accounts for 4,91 days but also the cause of this production system restriction determining that it takes place in the painting process therefore it was necessary to purpose the use of a drying oven to face this restriction, thus, it was tested showing 1 hour reduction in painting process time. On the other hand, a further manufacturing procees exploration showed that another cause of this production system restriction was in the pieces shaping, though the Layouth system it was determined that the production plant had only one baroladora therefore to face this restriction it was necesary to implement and additional one, wich allows to diminish the pieces shaping process time by half in regarding the time required initially. The study results revealed that the enterprise incomes were increased after this study proposal implementation since its productivity increased 13 – 27 forge garage doors a month which was reflected in the TIR incomes projection accounting for 272,98% as well as in 14,51 cost – benefit
