Design and Layout of Warehouses to Increase Productivity Using ABC and SLP Techniques in a Mining Company

This research addresses the design and optimized distribution of a mining spare parts warehouse to increase productivity using the ABC and Systematic Layout Planning (SLP) techniques. The current problem of the company under study is centered on poor manual inventory management, characterized by disorganization, lack of a strategic classification of materials and inefficient routes, which negatively impacts response times and the accuracy of records, directly affecting productivity and profitability. To address these challenges, a design is proposed that integrates the ABC technique for prioritizing products according to their value and rotation, together with SLP, to optimize the layout of the areas and internal flows of the warehouse. The initial diagnosis revealed critical deficiencies, including an inventory accuracy of 88.19%, an OTIF delivery efficiency of 87.41% and an overall productivity of 76.83%. The study is based on existing literature, highlighting the positive impact of tools such as 5S, Lean Warehousing and ABC-SLP analysis in optimizing operational productivity. The design proposal includes a "U"-shaped layout to minimize travel times and optimize the location of high-turnover products, validated through simulations to assess its impact on key performance indicators. After implementation and reduced time and distance travelled factors, 94.97% for FILL RATE and 93.12% for OTIF were obtained, an improvement of 7.05% and 5.71%, respectively.
