Dr. Melvin Hoyer Laboratory of Physical and Satellite Geodesy: 28 years of legacy and commitment to Geodesy in Venezuela

Ileanis Arenas, Victor Cioce, Hermógenes Suárez, Melvin Hoyer — Tue, 14 Jan 2025 00:00:00 +0000

En esta entrega del volumen 48 de nuestra Revista Técnica, rendimos homenaje al Laboratorio de Geodesia Física y Satelital Dr. Melvin Hoyer (LGFS-MH), una institución emblemática que ha desempeñado un papel fundamental en el desarrollo de la Geodesia en Venezuela durante 28 años. Desde su fundación en 1997, este laboratorio, adscrito al Departamento de Geodesia Superior de la Escuela de Ingeniería Geodésica, ha sido un pilar en la docencia, investigación y extensión, consolidando su prestigio a nivel nacional e internacional.

Hoy, el LGFS-MH celebra 28 años de trayectoria, consolidándose como referente en la investigación y formación geodésica en Venezuela. A pesar de los desafíos, su labor ha fortalecido el desarrollo científico y tecnológico del país. Su compromiso con la precisión y la innovación sigue siendo clave para el avance de la geodesia en la región.

Sequencing of tasks by algorithms through the theory of lean manufacturing in the cardboard sector

This study on the cardboard sector addressed various processes, such as printing, die-cutting, discarding, folding, and strapping, in a company with previously identified operational issues. Solutions were implemented using Lean Manufacturing tools and task sequencing algorithms. The analysis was structured in four stages: first, operational data was collected; next, Lean Manufacturing techniques were applied to optimize processes. The methodology was empirical-inductive, with data analysis and the implementation of sequencing algorithms. The justification focused on prioritizing a specific printer, achieving a 35% reduction in setup times, which led to a significant decrease in work hours. Sequencing algorithms were used to optimize task organization, leveraging collaborative tools like Google Collaborative. The results demonstrated that these algorithms improved processing times, reducing work hours by 57.6%, suggesting they are a viable alternative for optimizing the printing process in cardboard companies.

Systems dynamics model for the management of an undergraduate university academic program

The objective of this study is to design a system dynamics model that addresses the evolution of the population of an undergraduate program through a systemic and causal approach. The problem statement lies in the lack of comprehensive tools that allow for effective analysis and projection of this dynamics. The objective of this study is to develop a system dynamics model that tackles this issue through a systemic and causal approach. It proposes an approach that integrates key variables such as current student population, tuition costs and program economic outcomes, to provide a comprehensive view of the situation. The methodology is based on the utilization of a Forrester diagram for model construction, which allows for simulating the identified variables up to the year 2043. Additionally, an exhaustive literature review is conducted using databases such as Scopus and Google Academics to contextualize the proposed model. The main results of this research include the model's ability to project different scenarios, such as the lack of governmental economic assistance policies towards universities. Furthermore, it highlights the identification of relevant themes and variables through the literature review conducted. In conclusion, this study provides a comprehensive and robust model that enables the projection of student population evolution in an engineering program, thus offering a valuable tool for decision-making and long-term strategic planning in the academic field.
