Resumen
La presente investigación se realizó en la empresa Khanax SAC, una droguería que presentó
pérdidas de ingresos ocasionadas por la falta de disponibilidad de productos, atribuida tanto a
quiebres de stock como al extravío de artículos dentro de su almacén. La finalidad de este
estudio fue proponer la mejora de la gestión de inventarios para reducir los ingresos no
percibidos en la droguería Khanax SAC. Siendo en un estudio de tipo cuantitativa, de tipo
descriptiva y aplicativa, diseño transversal. Por ello, se aplicó la clasificación ABC y el modelo
P de gestión de inventarios con el propósito de establecer las cantidades óptimas a solicitar para
cada producto. Además, se introdujo una política de inventarios y así mismo, se optimizaron
los procesos logísticos de adquisición y almacenamiento. Obteniendo como resultado que la
rotura de stock se reduciría hasta el 3%, incrementando simultáneamente el nivel de servicio al
97%. En cuanto a los ingresos no percibidos, la oportunidad de venta no generada disminuiría
al 6.18%, mientras que por productos extraviados se reducirían al 1%. Estas modificaciones
implican una reducción del 11.6% en la rotura de stock, un aumento del 11.6% en el nivel de
servicio y descensos del 8.92% en la combinación de ingresos no percibidos, distribuidos en
una caída del 6.18% para oportunidades de venta y del 2.74% para productos extraviados. En
conjunto, los cambios propuestos reflejan una mejora sustancial en la disponibilidad de
inventarios, el cumplimiento de la demanda y la minimización de ingresos no percibidos no
generados por faltantes y extravíos. Finalmente, se obtuvo un costo/beneficio de 1.28 soles, un
VAN positivo y un TIR de 85.2% consiguiendo demostrar que es un proyecto rentable.
Concluyendo que la propuesta de mejora planteada, estima reducir los ingresos no percibidos
en un 50 % en la empresa.
This research was conducted at Khanax SAC, a drugstore that experienced revenue losses due to product unavailability, attributed to both stockouts and lost items within its warehouse. The purpose of this study was to propose improved inventory management to reduce lost revenue at Khanax SAC. This was a quantitative, descriptive, and applicative study with a cross-sectional design. Therefore, the ABC classification and the P inventory management model were applied to establish the optimal quantities to order for each product. Additionally, an inventory policy was introduced, and the logistics processes for procurement and storage were optimized. The result was a reduction in stockouts to 3%, while simultaneously increasing the service level to 97%. Regarding lost revenue, the lost sales opportunity decreased to 6.18%, while losses due to lost products decreased to 1%. These modifications imply an 11.6% reduction in out-of-stocks, an 11.6% increase in service levels, and an 8.92% decrease in the combined lost revenue, distributed as a 6.18% drop in sales opportunities and a 2.74% drop in lost products. Overall, the proposed changes reflect a substantial improvement in inventory availability, demand fulfillment, and the minimization of lost revenue generated by shortages and losses. Ultimately, a cost/benefit ratio of 1.28 soles, a positive NPV, and an IRR of 85.2% were obtained, demonstrating that this is a profitable project. The proposed improvement project is estimated to reduce lost revenue by 50% for the company.
