The main objective of this research is to increase productivity in a metalworking company in Peru, through the implementation of plant layout tools such as SLP and Lean tools, such as 5S and SMED. It is important to highlight that, in 2023, the metalworking industry represented 1.5% of the national Gross Domestic Product (GDP), contributing a value of 567,390 million soles, or 151,860 million of U.S. Dollars.

The issue identified in the workshop area, where cable trays are manufactured, is that productivity is 0.1831 finished products per man-hour. This corresponds to a manufacturing order of 200 linear meters of finished product. For the validation of the model, Lean methodology was used, applying the 5S and SMED tools to reduce non-productive activity times, such as area cleaning, tool and material selection, and equipment setup. Additionally, the SLP tool was used for plant redistribution, aiming to propose a new layout for the workshop area that included a raw material warehouse and a finished product warehouse.

The results obtained from the simulation of the proposed model with Arena software showed that, by implementing a plant redistribution with two warehouses (one for raw material and one for finished product), and reducing activity times, productivity increased to 0.2168 trays produced per man-hour, with a simulated production time of 12.14 days.
