Estudo da viabilidade da implantação de um sistema de produção puxado em uma empresa de embalagens flexíveis: um estudo de caso

Abstract

In today's global business scenario, as companies incessantly seek to increase their competitiveness, cost reduction, product improvement, adding more value to the customer and differentiating from the competition or by specialization in any segment or niche market. Improvements in production systems are a focus of long-term studies, and various formulas, methods and tools have already been created in different locations around the globe to increase productivity and reduce costs. Two major philosophies of improvement are the Toyota Production System (STP) or lean production and the Theory of Constraints (TOC).These two philosophies, mainly lean production, are venerated by the great majority of companies, and regarded as the universal salvation for all productive models in the world. In order to study this assertion, this work aims to analyze the implementation of a production line drawn through kanban cards in a flexible packaging industry. Based on the bibliographical review, there were several concepts of lean production as well as the Theory of Constraints, as well as analyzes about the layout of the factory and elaboration of time series for the knowledge of the behavior of the sector's demand. In conclusion, the system pulled by kanban cards was not convincing due to the particularities presented by the sector, the viability of a productive system depends not only on the company's will, but also on external and internal factors such as income distribution, the political environment. Which involves the company, the relationship with the worker, other aspects. Some of the tools found in both philosophies can be applied in future works, such as calculations of statistical fluctuations in processes and kaizen continuous improvement events.
