Resumen

In small and medium-sized construction enterprises (SMEs), particularly those operating in geographically dispersed regions, inefficiencies in material management represent a critical operational challenge. Inadequate material planning, limited inventory visibility, and inefficient warehouse layouts frequently result in stockouts, incomplete deliveries, and project execution delays. These issues directly affect the On-Time In-Full (OTIF) indicator, generating financial losses due to penalties, rework, and idle labor hours, as observed in construction companies in the Amazonas region of Peru. Although previous studies have demonstrated the individual benefits of Material Requirements Planning (MRP), Internet of Things (IoT) technologies, and warehouse layout optimization techniques, their isolated implementation often produces fragmented improvements. This research addresses this gap by proposing an integrated model that combines MRP for structured material planning, IoT for real-time inventory monitoring, and Systematic Layout Planning (SLP) for warehouse redesign. The projected results indicate an increase in OTIF performance from 66.67% to a range between 78% and 80%, a reduction in stockouts to below 5%, and an improvement in inventory accuracy to above 93%. These projections are grounded in structured benchmarking and expert validation.
