Optimization of the Accounts Payable Process in a Mid-Sized Credit Union
(Polytechnic University of Puerto Rico, 2025) Príncipe Morales, Kelvin; Cruzado Vélez, Héctor J.
Automation alternatives were evaluated to improve the accounts payable process of a mid-sized credit union operating in a regulated financial environment. The existing process relied on manual document handling, informal approval practices, and repetitive data entry, resulting in processing delays and operational risk. A structured methodology was applied, including workflow mapping, bottleneck identification, process metrics analysis, and a weighted evaluation of automation alternatives. The results showed that workflow-based automation offered the most feasible improvement option by enhancing document control, approval routing, and process visibility without requiring direct core system integration. Robotic process automation was identified as a potential future enhancement to further reduce manual data entry. Key Terms ⎯ accounts payable automation, credit unions, process automation, workflow automation.
Procedimiento para la Toma de Decisiones en Proyectos Típicos de Estabilización de Taludes en Infraestructura Vial en Puerto Rico
(Polytechnic University of Puerto Rico, 2025) Munet Arizmendi, Jorge L.; Cruzado Vélez, Héctor J.
Este proyecto desarrolló un procedimiento gerencial estructurado para apoyar la toma de decisiones en proyectos típicos de estabilización de taludes en infraestructura vial en Puerto Rico. El estudio se enfocó en la etapa de planificación del proyecto, donde la selección de alternativas de estabilización se vio
influenciada por restricciones de costo, tiempo, riesgo e impacto operacional. La metodología se basó en la identificación de escenarios recurrentes en proyectos viales, la definición de criterios gerenciales de evaluación y el desarrollo de un método estructurado para la comparación consistente de alternativas. Como resultado, el procedimiento permitió evaluar opciones técnicamente viables desde una perspectiva gerencial, facilitando decisiones más transparentes y fundamentadas. Se concluyó que el uso de un procedimiento estructurado contribuye a mejorar la consistencia del proceso de selección de alternativas y apoya la
gestión efectiva de proyectos de estabilización de taludes en infraestructura vial.
Improving Indoor Air Quality and HVAC Performance Using the PDCA Methodology
(Polytechnic University of Puerto Rico, 2025) Muñoz Quinones, Jhonnathan; Cruzado Vélez, Héctor J.
Improving indoor air quality (IAQ) is essential for enhancing occupant health, productivity, and building performance. This project applied the PDCA (Plan-Do-Check-Act) methodology to optimize HVAC systems and reduce harmful air pollutants. Key improvements included lowering CO₂ levels, reducing PM2.5 and VOC concentrations, optimizing relative humidity, and refining temperature control. These changes align with ASHRAE 62.1 standards and contribute to
energy efficiency and sustainability. The methodology ensures continuous improvement through iterative evaluation and adjustment. The results demonstrate measurable benefits in health outcomes, cognitive performance, and operational efficiency, making this approach a practical framework for IAQ enhancement in commercial and institutional buildings. Key Terms ⎯ Air Quality, HVAC Optimization, PDCA Cycle, Sustainability.
Enhancing Field Issue Resolution Workflow for Compressor Components
(Polytechnic University of Puerto Rico, 2025) Lopez Rosas, Irving J.; Cruzado Vélez, Héctor J.
Field investigations of compressor components are essential to maintaining aircraft engine reliability and fleet availability, but investigation closure times are often extended due to incomplete intake data and sequential engineering coordination. This study evaluates compressor component investigation workflows
within a centralized aerospace engineering support organization and develops process improvements using Agile engineering management principles. A
baseline review of four representative investigation cases, supported by stakeholder interviews and workflow mapping, identified primary delay drivers and coordination challenges. Improvement initiatives were implemented through two Agile sprints focusing on intake data standardization and workflow execution efficiency. The improvements were integrated into a future-state workflow model incorporating mandatory intake checklists, parallel multidisciplinary engineering assessments, early quality and safety engagement, and centralized investigation tracking. The proposed workflow is expected to reduce investigation closure time by approximately 25 to 35% while improving communication efficiency and technical consistency. The results demonstrate the
effectiveness of Agile methodologies in improving multidisciplinary aerospace investigation workflows. Key Terms ⎯ Agile engineering management;
Aerospace field investigations; Maintenance, repair, and overhaul (MRO); Process standardization.
