In 2018, Peru held 5% of the textile apparel market since China reduced its baby clothing exports to the US market by 12.3%. However, many textile companies around the world were not able to meet customer demands due to poor supply chain planning and ineffective production systems. Similarly, companies in the local textile SME industry are often not able to comply with order deadlines. Within this context, this paper presents a case study of a medium-sized textile company in Peru, which reports similar problems to other companies due to non-fulfilled orders. For these purposes, the Standardization and Systematic Layout Planning (SLP) tools are proposed under a Plan-Do-Check-Act (PDCA) environment with the objective of improving takt-times and the percentage of Non-Value-Adding (NVA) activities, which will lead to a 25% reduction in Production Lead Times, thus fulfilling and delivering all orders to the required market. On the other hand, 3 scenarios will be proposed and, to validate each of the proposed results, the Arena Simulator was used, which allows for a 95% confidence level.
