Storage management model based on Lean Warehouse Management and Systematic Layout Planning

Abstract

The logistics and storage sector in Peru has experienced significant growth due to increased imports and the trend among companies to outsource their storage processes. This article addresses the challenge of enhancing warehouse efficiency, particularly in the picking and location processes, through a warehouse management model. The methodology employed includes a company diagnosis, Value Stream Mapping, the 5S methodology (a Lean Warehouse Management tool), and Systematic Layout Planning. These approaches aim to improve inventory management and human resource utilization to reduce late order rates. This research demonstrates the application of Lean tools in warehouse management, an innovative concept in Peru, with positive outcomes: reducing the late order rate from 14.69% to 3.71%. Moreover, it proves economically viable with a positive net present value (NPV) of S/. 12,659 and an internal rate of return (IRR) of 45.03%. This study contributes to promoting research for enhancing warehouse processes in Peru, addressing a gap in scientific literature on this topic.
