Análisis y Mejora del Procesamiento de Órdenes de Compras en el Canal de Ventas de Distribución de La Española Beauty Supply
(Universidad Politécnica de Puerto Rico, 2026-05) Guzmán, Sofía I.; Burtell Lugo, Carlos A.; Santiago Miranda, Eliel C.; González Miranda, Carlos J.; Universidad Politécnica de Puerto Rico, San Juan Campus, Industrial and Systems Engineering Department, Industrial Engineering Program
Este proyecto sintetiza los hallazgos principales del proyecto titulado “Análisis y Mejora del Procesamiento de Órdenes de Compra en el Canal de Ventas en el Centro de Distribución La Española Beauty Supply” desarrollado como parte del curso de Capstone (IE 4990, IE 4995) en el departamento de Ingeniería Industrial de la Universidad Politécnica de Puerto Rico. Este proyecto tiene como propósito principal evaluar y optimizar el proceso de preparación y despacho de órdenes mediante la aplicación de la metodología DMAIC, con el fin de mejorar la eficiencia operativa y la calidad del servicio al cliente.
Optimización de la Operación de Almacenamiento y Tiempo de Despacho en RC Imports
(Universidad Politécnica de Puerto Rico, 2026-05) Díaz Sánchez, Kevin A.; Bermúdez Abreu, Carlos A.; Cruz Figueroa, Víctor R.; González Miranda, Carlos J.; Universidad Politécnica de Puerto Rico, San Juan Campus, Industrial and Systems Engineering Department, Industrial Engineering Program
El presente proyecto Capstone fue desarrollado en RC Imports LLC, empresa puertorriqueña dedicada a la importación y distribución mayorista de productos de consumo con instalaciones en Carolina y Mayagüez, Puerto Rico, aplicando la metodología Lean Six Sigma bajo el ciclo DMAIC con el objetivo de mejorar el control de inventario y la eficiencia operativa del almacén. Los dos problemas principales identificados fueron la acumulación de productos obsoletos y la ineficiencia en el proceso de despacho de órdenes, ambos generando pérdidas económicas, atrasos y baja satisfacción del cliente. En la fase Define se identificó que la empresa recibía entre una y dos quejas diarias por errores de inventario, que aproximadamente el 25% de las órdenes se retrasaban o cancelaban por falta de disponibilidad real del producto y que la comunicación interna entre almacén y ventas era evaluada con apenas un 2 sobre 10 por la propia empresa, confirmando la necesidad urgente de intervenir en los procesos de inventario y despacho. La fase Measure cuantificó el impacto de estos problemas mediante el ABC Analysis, que reveló que la Categoría A concentraba 730,852 unidades vendidas lideradas por el producto XXL Platinum Zero con 255,522 unidades, y el análisis de tiempos del proceso, que confirmó que el Paso 5 de despacho al cliente representaba el cuello de botella más crítico con un promedio de 96 horas frente a apenas 4.8 horas acumuladas en los cuatro pasos anteriores. En la fase Analyze se validaron las causas raíz mediante el Diagrama de Fishbone, el análisis de los 5 Whys, el Box Plot comparativo, los Scatter Plots y el análisis de tiempo promedio de picking por día. Los datos recopilados demostraron que el Picker 1 operaba con un promedio de 35.9 minutos por orden mientras que el Picker 2 promediaba 86.4 minutos, con una variabilidad del 86% en el proceso. Con una demanda promedio de 49 órdenes diarias y una capacidad combinada de apenas 19 órdenes, el sistema solo cubría el 38.8% de la demanda real, generando un atraso acumulado de dos días o más. Se determinó que la causa raíz fundamental era la ausencia de un layout organizado, procedimientos operativos estandarizados y un sistema formal de gestión del almacén.
Reducing Visual Defect Rates (%) in Concerta Tablets for Fuji Japan Inspection
(Polytechnic University of Puerto Rico, 2026-05) Baella Anzalota, Ignacio; Avilés Reymundí, Gloriangely; López Irizarry, Ana; González Miranda, Carlos J.; Universidad Politécnica de Puerto Rico, San Juan Campus, Industrial and Systems Engineering Department, Industrial Engineering Program
This Capstone project applies the DMAIC methodology to reduce the visual defect rate of Concerta tablets manufactured at the Johnson & Johnson Innovative Medicine Gurabo site for the Japan market. The project focuses on the 18 mg, 27 mg, and 36 mg dosage strengths and includes the manufacturing process from granulation through tablet counting. The customer-detected defect signal occurs during Fuji, Japan AQL inspection prior to packaging. During the Define phase, the team established the business context, project scope, customer requirements, process boundaries, stakeholder map, high-level process flow, SIPOC, and CTQ requirements. The Voice of the Customer was developed using three sources: Fuji Japan AQL inspection data, operator survey results across manufacturing shifts, and interviews with OROS manufacturing leadership and supervision. These inputs consistently point to visual defects primarily related to printing and coating integrity. During the Measure phase, the team quantified the current problem using both historical Fuji defect data and an NC Investigation Defect Catalog covering December 2024 through December 2025. Historical AQL sampling across 93 bulk lots identified 20,415 visual defects, with printing defects representing 51.7% and coating-related defects representing 24.4% of the total defect count. Together, these two categories account for 76.1% of all defects identified in the historical Fuji data. More recent customer data confirmed that Concerta defect rates exceeded target levels for all three dosage strengths reviewed. The 18 mg strength had an average defect rate of 2.28% compared to a target of ≤1.80%, the 27 mg strength had an average defect rate of 5.68% compared to a target of ≤4.00%, and the 36 mg strength had an average defect rate of 0.89% compared to a target of ≤0.80%. The measurement baseline indicates that the defect pattern is not random. Printing-related issues and coating failures dominate the investigation data, with Concerta 18 mg and 27 mg representing the highest concentration of investigations. Several lots also recur across multiple investigations, indicating potential process stability concerns. These findings support a focused Analyze phase centered on process stability, defect detection capability, setup variation, and the process conditions associated with printing and coating defect occurrence.
Strategic Management of Electrical Distribution Infrastructure for the Valley Village Affordable Housing Development
(Polytechnic University of Puerto Rico, 2026) De La Cruz Corujo, Ricardo Jr.; Cruzado Vélez, Héctor J.
This project developed a strategic electrical distribution infrastructure solution to support the interconnection to the Valley Village affordable housing development in Santa Isabel, Puerto Rico, consisting of approximately 300 residential units with a projected demand of 2,150 kVA. Operational studies confirmed that the existing 4.16 kV feeder operated at approximately 90% of its loading capacity, resulting in thermal loading and voltage regulation limitations that restricted additional load integration. Engineering analyses, including load flow simulations, voltage drop evaluations, and distribution design validation, were conducted to identify feasible interconnection alternatives. The methodology followed the PMBOK framework and incorporated a structured decision matrix based on technical feasibility, reliability, cost efficiency, and operational risk. The selected 13.2 kV feeder extension was developed to an execution-ready level within the established $800,000 project budget. The resulting solution is expected to improve system capacity, enhance voltage performance, and suppotrt long-term reliability and future load growth.
Improving Integration of External Contractor Activities into the Lead Maintenance Activity Integrated Production Schedule
(Polytechnic University of Puerto Rico, 2026) Montes La Santa, Wilfredo; Cruzado Vélez, Héctor J.
This project evaluated the integration of external contractor activities into the Lead Maintenance Activity Integrated Production Schedule at FDRMC Rota to improve compliance with NAVSEA Standard Item 009-060, using the DMAIC methodology. Baseline analysis showed contractor integration performance was approximately 60%, significantly below the 95% target. Pareto and Fishbone analyses identified late submissions, deficient data quality, missing logical relationships, and lack of a centralized Work Integration Manager role as the primary contributors to integration deficiencies. A structured improvement framework was developed to improve schedule visibility, coordination, and long-term compliance.
