Proposta de implementação da metodologia SMED: redução de paradas planejadas na troca de formato da linha de sachê

Abstract

Driven by the need to reduce waste and increase operational efficiency, this study applies the Single Minute Exchange of Die (SMED) methodology to a powdered milk sachet packaging line in the food industry. The study aimed to identify opportunities for improvement in the format changeover process in order to reduce setup time and, consequently, planned downtime on the production line. To achieve this objective, an applied research approach was adopted, using a qualitative-quantitative methodology with exploratory and descriptive objectives and action research procedures. The methodology followed the stages of definition, measurement, analysis, and control, supported by improvement analysis and prioritization tools. Through the assessment and categorization of setup activities, opportunities related to operation standardization, process parameter review, and waste elimination were identified. Based on the analyses performed, an action plan was developed, and a simulation of the expected results was conducted, indicating the potential for setup time reduction, increased operational stability, and improved production line performance. The findings demonstrate that the SMED methodology is an effective tool for identifying and implementing improvements in format changeover processes.
