Mejora de la productividad mediante la aplicación de la teoría de restricciones en la fabricación de sillas de la Empresa Muebles de acero Viteri.

Abstract

More and more companies are using continuous improvement tools in order to satisfy the requirements of their customers and to stay in a competitive market. The general objective of this research was to improve the productivity in the manufacturing process of chairs of the company "Muebles de Acero Viteri", applying the theory of restrictions. Through the use of scientific techniques for the study of work, such as timing, direct observation of procedures and diagrams of processes and routes, data was obtained from the current method with which the factory worked. Subsequently, based on the methodology of value added analysis, it was identified that the main restriction of the process was in the waiting time for the cooling of the chair structures, which is part of the curing and baking stage. In order to exploit the restriction, in the technical phase of this investigation, standardization of the process times was carried out and in the technological phase an axial fan was implemented under design that allowed a 32% reduction in the waiting time and an increase in the index of production in a 35.44% with a maximum capacity of 215 monthly chairs. The improved method also showed that it financially generates a cost benefit index of $ 41.05 and an increase in throughput for the organization. That is, the theory of restrictions is an effective tool in the mitigation of bottlenecks, for this reason, the factory must work permanently supported by improvement methodologies that contribute to the achievement of its goals.
