Increasing Operational Efficiency in a Personal Care SME Through SMED, TPM, and IoT Within an Industry 4.0 Environment
摘要
This study develops and validates an integrated improvement model aimed at increasing operational efficiency in the liquid production line of a Peruvian personal care SME. The model combines SMED, TPM (Pillars 1 and 2), and IoT technologies within an Industry 4.0 framework. SMED reduced changeover times by 26.2% through task classification and standardization. TPM Pillar 1 improved technical availability by 21.6% via autonomous maintenance, while Pillar 2, supported by IoT-based dashboards and sensor alerts, minimized unplanned downtime by 35.2%. The combined implementation was validated through in-plant pilot tests and discrete-event simulation using Arena. Results showed a projected increase in OEE of over 15% and an IRR of 122.56%, confirming both technical and economic feasibility. The model presents a replicable path for digital transformation and continuous improvement in resource-constrained MTO environments.
