APPLICATION OF LEAN LOGISTICS TO IMPROVE ON-TIME DELIVERY OF TRANSPORTATION SERVICES IN A LOGISTICS COMPANY

Resumen

This project aims to improve the On-Time Delivery (OTD) of the transport service in a logistics company to boost operational efficiency and competitiveness. The problem stems from a current OTD of 58.81%, well below the sector benchmark of 90.2%, creating a technical gap of 31.39% and annual overcosts of S/ 214,140.00. To address these deficiencies, we apply Lean Logistics, combining a KPI analysis, a Systematic Literature Review (SLR), and root-cause analysis using Ishikawa diagrams to identify critical factors such as mechanical failures, misallocation of resources, and inefficient planning. Building on this diagnosis, we propose an improvement package based on Total Productive Maintenance (TPM), Work Standardization (WS), and a Transportation Management System (TMS), assessing its effectiveness through discrete-event simulation. Results from the pilot and validation with 30 simulation replicas (error less than or equal to 3.32%) demonstrated significant improvements: OTD increased from 58.81% to 82.52%, fleet utilization rose from 60.80% to 80.80%, Route Time Efficiency (RTE) reached 92.60%, and First Attempt Delivery Rate (FADR) improved to 84.96%. Economically, the project projects a benefit of S/ 656,618.62 over six months, confirming the scalability and viability of the proposed model.
