Resumen

Improving On-Time Delivery (OTD) in manufacturing SMEs requires addressing variability and material availability simultaneously. This paper proposes a low-cost Lean-Digital Kanban approach for a Peruvian metalworking SME producing gas stoves. Using a 2024 order trace (N = 148), baseline OTD is 73.65% and the critical two-burner family reaches 70%, with annual delay losses of USD 18,776. The model combines variability reduction (5S/SMED/standardized work/TPM) with BOM-driven Digital Kanban replenishment. Hybrid validation - benchmark bounds plus DES - shows OTD exceeding 90% and penalty reduction of approximately 86%, feasible with minimal digital investment.
