The textile sector is one of the most competitive markets globally and nationally, so companies are increasingly aware that they must constantly innovate and eliminate waste such as preparation times for product change, adjustment and unscheduled stoppages. This waste in the machines causes an increase in the percentage of defective products and efficiency of the line is poor, which generates that companies are forced to reject orders and as a consequence fail to meet the market demand. This research aims to propose a maintenance management model to increase the efficiency of garment manufacturing in textile companies that are affected by unplanned shutdowns and very long set up times that reduce processing times. Likewise, the objective of this research is to increase the production efficiency of medium-sized companies in the textile sector, through a model based on TPM and SMED, which belong to the Lean Manufacturing philosophy and will be developed jointly to reduce unplanned stops due to failures and breakdowns in the machines and reduce high preparation times through standardization.
