Proposta de melhorias através da padronização de processo: um estudo de caso na montagem de componentes em uma linha de produção automotiva

Abstract

In search of improving its competitiveness in the market, an organization must establish the operational excellence of its processes, through the concept of lean competence, an organization that adheres to its fundamentals is in constant search for excellence. In the case study under study, some work cells were identified that present destandardization in relation to the design of the established process. We will focus our attention on the cells that demonstrate the greatest criticality, as challenges related to quality, standardization of procedures and time are concentrated there. These issues are interconnected with indicators that measure operational efficiency, productivity, flexibility, organizational climate, and quality. The present work aims to study and apply Lean tools to improve the efficiency of a work cell, through mapping its entire production process. The methodologies adopted were based on qualitative and quantitative bibliographical research which involved mapping work cell processes, carrying out time studies using the chrono analysis tool, presenting improvements in cells after balancing operations and standardizing the process, Lean Thinking and Lean Manufacturing. In this way, it was possible to implement improvements in the studied work cell, which contributed to a reduction of 14.47% in the indicator that measures quality performance in the production process and 0.9% in the indicator that measures the number of vehicles that they break the production flow to carry out rework. In addition to quality gains, it was also possible to obtain gains in relation to the fairness of the operator’s workload.
