Currently, in the textile sector there are different opportunities to improve productivity and reduce production costs originating from various factors such as excess waste and waste of materials, delay in manufacturing and delivery of orders with negative effects on income. of the company. The objective of the research is to develop a production management model to reduce production costs in the curtain making process of a textile mype in the city of Lima, Peru, using an empirical research design, from a quantitative approach to explanatory level in the case study modality, presenting an engineering solution model validated through simulation techniques. A diagnosis of the situation found was made by applying the Value Stream Mapping (VSM) technique; accompanied by an analysis of the root causes of the identified problems and the analysis of research background on the subject, the System Layout Planning (SLP) technique was selected as a solution tool. The solution model was validated through the simulation technique using the Arena software, finding that production costs decreased by 3.74% compared to the initial situation.
