Abstract

The increase in occupational accidents and ergonomic risks in intralogistics operations represents a recurring problem in warehouses, especially during loading, unloading, and material handling activities, where traditional layout and optimization tools are insufficient to simultaneously integrate operational and human criteria. In response to this issue, this study developed and validated an integrated warehouse design framework aimed at reducing ergonomic risks and improving operational performance. The proposed approach combines the Supplier-to-Warehouse model, ABC inventory analysis, and a user-centered hybrid Variable Neighborhood Search–Genetic Algorithm (VNS-GA). A mixed-methods, quasi-experimental approach was applied in two SMEs located in Hidalgo, Mexico. Results showed significant improvements in operational times, travel distances, productivity, incident reduction, and ergonomic risk, demonstrating that integrating ergonomic and operational criteria enhances efficiency, safety, and worker well-being.

Reducción de riesgos ergonómicos en intralogística: combinación de Supplier-to-Warehouse, análisis ABC y un algoritmo híbrido VNS-GA centrado en el usuario

Resumen:
El aumento de los accidentes laborales y de los riesgos ergonómicos en las operaciones intralogísticas representa un problema recurrente en los almacenes, especialmente durante las actividades de carga, descarga y manipulación de materiales, en las que las herramientas tradicionales de distribución de planta y optimización resultan insuficientes para integrar simultáneamente criterios operativos y humanos. En respuesta a esta problemática, este estudio desarrolló y validó un marco integrado de diseño de almacenes orientado a reducir los riesgos ergonómicos y mejorar el desempeño operativo.

El enfoque propuesto combina el modelo Supplier-to-Warehouse, el análisis ABC de inventarios y un algoritmo híbrido de Búsqueda de Vecindad Variable–Algoritmo Genético (VNS-GA) centrado en el usuario. Se aplicó un enfoque de métodos mixtos con diseño cuasiexperimental en dos pequeñas y medianas empresas (PYMES) ubicadas en Hidalgo, México.

Los resultados mostraron mejoras significativas en los tiempos operativos, las distancias recorridas, la productividad, la reducción de incidentes y el riesgo ergonómico, lo que demuestra que la integración de criterios ergonómicos y operativos mejora la eficiencia, la seguridad y el bienestar de los trabajadores.
