Small and medium-sized companies in the textile sector have deficiencies in the production area. It happened because they do not have a standardized process and adequate machine maintenance management. For this reason, analyzing the initial diagnosis of an SME company dedicated to textile printing presented problems in design and printing. Based on this, this research developed a proposed model to reduce the return rate, improve work areas' organization, and optimize delivery times. The production model is developed based on the Lean BPM (Business Process Management) and TPM (Total Productive Management) tools through a 5s continuous improvement approach. The improvement proposal is validated in the Arena 14 software, reducing the failure rate of the machines and the rate of returns from 7.95% to 5.97%

The foam furniture paint industry, belonging to the manufacturing sector, has experienced a decline in recent years due to the COVID-19 pandemic. This situation has negatively impacted production capacity and has generated significant challenges. Among them, reprocessing has occurred due to undesired tones in the paints, the presence of residues in the machines, as well as errors in machinery programming and delays in the start of production. These factors have hindered the manufacturing sector from reaching its pre-crisis economic level. Consequently, delays in the delivery of the final product arise, leading to economic losses for the companies, which hinder their development. To address these issues and thereby reduce product delivery times, the production improvement model based on Lean Manufacturing tools is proposed. The model consists of tools such as 5S, Poka-Yoke, and standardiz...
