Resumen

The central problem of this study was the inefficiency in the printing process of a plastic bag manufacturing company in Lima, Peru. This was evidenced by an Overall Equipment Effectiveness (OEE) of 51.64% and an availability of 56.53%, values far below international reference standards (85% and 90%, respectively). The main objective was to increase the availability of the printing machine to 85.46% in order to improve the OEE by addressing root causes such as critical component failures and excessive changeover and setup times. To address this problem, industrial engineering tools were applied, specifically Single Minute Exchange of Die (SMED) and Planned Maintenance. Improvement actions were defined based on real operational data from the company, and their impact was evaluated through a discrete-event simulation model of the printing process developed in Arena software, allowing a comparison between the current and proposed states. The simulation results showed an increase of 3.92% in machine availability, which led to a 3.58% improvement in OEE. These results indicate that the joint application of SMED and Planned Maintenance contributes to a more stable and efficient production process and may be transferable to other manufacturing contexts.
