Abstract
Este documento presenta un estudio exhaustivo sobre la optimización de la gestión de inventarios en Serviall S.A., una empresa en la industria minera. El objetivo principal es desarrollar un modelo de gestión de inventarios mas eficiente y adaptado a las particularidades de esta industria, mejorando así la eficiencia operativa y reduciendo costos, comparativamente respecto de la Política de Inventarios aplicada actualmente.
La industria minera enfrenta desafíos únicos en la gestión de inventarios, incluyendo alta variabilidad en la demanda, particularidades en los productos, y complejidades en la cadena de suministro. Estos desafíos exigen un modelo de gestión que sea flexible, robusto y capaz de adaptarse a cambios rápidos en el mercado y en las condiciones de suministro.
Se analizaron diversos modelos, incluyendo clasificación ABC, revisión continua, revisión periódica, Modelo Lote por Lote, Cantidad Económica de Pedido y Modelo de Punto de Reorden. Cada modelo fue evaluado por sus ventajas y desventajas en el contexto de la industria minera. Se concluyó que un enfoque hibrido, el cual combine elementos de estos modelos, sería el más efectivo para Serviall S.A., al ser fundamental la factibilidad de la aplicación del modelo de definir. Para validar el modelo propuesto, se realizaron pruebas retrospectivas con datos históricos de la empresa y simulaciones en diversos escenarios. Estas pruebas demostraron la capacidad del modelo para mejorar la eficiencia y reducir costos, al tiempo que destacaron la importancia de tener datos precisos y mecanismos de adaptabilidad a cambios inesperados en la demanda y la cadena de suministro.
Se recomienda que Serviall S.A. adopte un modelo hibrido de gestión de inventarios, complementado con un sistema de información robusto y un plan de contingencia para la cadena de suministro. Este enfoque no solo mejorara la gestión de inventarios, sino que también aumentara la eficiencia operativa y la competitividad en el mercado. El rediseño de la política de gestión de inventarios en Serviall S.A. es un paso crucial hacia la mejora de la eficiencia operativa y la reducción de costos. El enfoque hibrido propuesto ofrece la simpleza, flexibilidad y robustez necesarias para enfrentar los desafíos únicos de esta industria, posicionando a Serviall S.A. para un éxito sostenido en un entorno de mercado volátil y competitivo.
Serviall S.A., a Company in the mining industry. The main goal is to develop a more efficient inventory management model tailored to the specifics of this industry, thereby improving operational efficiency and reducing costs. The mining industry faces unique challenges in inventory management, including high demand variability, particularities of products, and complexities in the supply chain. These challenges demand a management model that is flexible, robust, and capable of adapting to rapid market and supply condition changes. Various models were analyzed, including ABC Clasification, continuous review, periodic review, batch model, Economic Order Quantity and reorder point model. Each model was evaluated for its advantages and disadvantages in the context of the mining industry. It was concluded that a hybrid approach, combining elements of these models, would be the most effective for Serviall S.A. To validate the proposed model, retrospective tests with historical company data and simulations in various scenarios were conducted. These tests demonstrated the model’s ability to improve efficiency and reduce costs, while highlighting the importance of having accurate data and mechanisms to adapt to unexpected changes in demand and the supply chain. It is recommended that Serviall S.A. adopt a hybrid inventory management model, complemented by a robust information system and a contingency plan for the supply chain. This approach will not only improve inventory management but also increase operational efficiency and market competitiveness. Redesigning the inventory management policy in Serviall S.A. is a crucial step towards improving operational efficiency and reducing costs in the mining industry. The proposed hybrid approach offers the simplicity, flexibility and robustness needed to meet the unique challenges of this industry, positioning Serviall S.A. for sustained success in a volatile and competitive market environment.
