Item type:Publication, IoT-Based Smart Gas Meter With LTE Connectivity and Cloud Analytics for Stationary Tanks(Institute of Electrical and Electronics Engineers (IEEE), 2026); ; Millions of homes in developing countries rely on stationary LPG tanks, yet the methods for monitoring fuel levels remain manual, unsafe, and highly inefficient. This paper addresses this issue by presenting the design, development, and implementation of an IoT-based smart gas meter that uses a noninvasive Hall-effect sensor to digitally read existing level gauges. Data is transmitted via LTE, eliminating the need for Wi-Fi and optimizing connectivity. The system is designed for low power consumption, achieving a battery life of more than eight years. Additionally, a cloud architecture is implemented in AWS to process the collected data, allowing real-time analysis, predictive maintenance, and logistics optimization. A field test was also conducted with 15 prototypes, demonstrating accurate gas level monitoring, reliable refill detection, and gas theft prevention. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Implementation of a Challenge-Based Learning Model for Higher Education Under a Modular Education System: A Case Study(IEEE, 2024); Chong, MarioAs student profiles and industry expectations modify, universities must advance learning methodologies to deliver more suitable graduates to the labor market. The Universidad Privada Boliviana (UPB) has developed experiential learning practices by implementing challenge-based learning (CBL) to enrich undergraduate curricula. One example of the CBL experiences was developed by the Taquiña Brewery, one of the five breweries of the Cervecería Boliviana Nacional (CBN), for the Industrial and Systems Engineering Department of the UPB between 2018 and 2019. As a result, students widely accepted the methodology, and academics from all disciplines in the university were trained to replicate CBL experiences in their classrooms. Moreover, the CBN found the opportunity to hire new talent, receive a fresh perspective on recurrent operational issues, and find new ideas based on theoretical concepts. This work exemplifies innovative approaches to enhance teaching and learning in supply chain management and logistics education. ©The authors ©IEEE.6 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Situational Awareness Errors in Forklift Logistics Operations: A Multiphase Eye-Tracking and Think-Aloud Approach(MDPI, 2024); Background: This study explores forklift operators’ situational awareness (SA) and human errors in logistic operations using a multiphase approach as an innovative methodology. Methods: Ethnography, eye tracking, error taxonomy, and retrospective think-aloud (RTA) were used to study the diverse cognitive, behavioral, and operational aspects affecting SA. After analyzing 566 events across 18 tasks, this research highlighted eye tracking’s potential by offering real-time insights into operator behavior and RTA’s potential as a method for cross-checking the causal factors underlying errors. Results: Critical tasks, like positioning forklifts and lowering pallets, significantly impact incident occurrence, while high-cognitive demand tasks, such as hoisting and identifying pedestrians/obstacles, reduce SA and increase errors. Driving tasks are particularly vulnerable to errors and are the most affected by operator risk generators (ORGs), representing 42% of incident risk events. This study identifies driving, hoisting, and lowering loads as the tasks most influenced by system factors. Limitations include the task difficulty levels, managing physical risk, and training. Future research is suggested in autonomous industrial vehicles and advanced driver assistance systems (ADASs). Conclusions: This study provides valuable insights into how we may improve safety in logistics operations by proposing a multiphase methodology to uncover the patterns of attention, perception, and cognitive errors and their impact on decision-making. ©The authors ©MDPI15 1 - Some of the metrics are blocked by yourconsent settings
