Reflecting on an Inspiring Presence at GITEX GLOBAL 2024

GITEX GLOBAL 2024 was an unforgettable experience for our team, filled with insightful discussions, exciting innovations, and invaluable connections. We are deeply grateful to the organizers for hosting such a remarkable event, bringing together tech leaders, innovators, and industry experts from around the world.

A highlight of our participation was the visit of Mr. Demetris Skourides, Chief Scientist of Research, Innovation, and Technology of the Republic of Cyprus. As NAVARCHOS is proudly funded by the Research & Innovation Foundation (RIF), it was an honor to present our progress and showcase how predictive maintenance is transforming fleet management through AI-driven solutions. By forecasting maintenance needs before issues arise, we enhance operational efficiency, reduce downtime, and extend asset lifespan—helping businesses stay ahead in a demanding market.

Beyond showcasing our technology, GITEX was an opportunity to engage with brilliant minds and exchange ideas that will shape the future of AI and innovation. The enthusiasm and insights shared by visitors at our booth were truly inspiring, reinforcing our commitment to pushing the boundaries of technology.

As we look ahead, we remain excited about the opportunities that lie ahead in the evolving world of AI and fleet management. Thank you to everyone who visited, engaged with us, and contributed to this incredible journey—we look forward to continuing the conversations and building lasting partnerships.



We are pleased to share that our team recently presented at the 18th Hellenic Database Management Symposium, which took place on July 1-2, 2024, in Athens, Greece.

Our presentation focused on "Exploring Unsupervised Anomaly Detection for Vehicle Predictive Maintenance with Partial Information," a study by Apostolos Giannoulidis, Anastasios Gounaris, and Ioannis Constantinou.

Presentation Highlights:

The talk focused on predicting maintenance needs in vehicle fleets to enhance safety and minimize downtime. While built-in alert systems from vehicle manufacturers often fail to notify drivers of potential issues, we explored how data analytics and real-time signals could address this problem. In a challenging real-world setting with limited and partial failure data, we proposed a non-supervised approach that detects behavioral changes related to failures without relying directly on raw signals, thereby handling variability in driving behavior and weather conditions.

Our solution calculates differences in the correlations of collected signals across two periods and dynamically creates reference profiles of normal operational conditions, effectively tolerating noise. Initial experiments showed promising results, achieving 78% precision in detecting nearly half of the failures, outperforming a state-of-the-art deep learning technique. Furthermore, we presented our approach as an instance of a broader framework, evaluating a wide range of alternatives.

Key Takeaways:

  • Non-supervised anomaly detection approach for predictive maintenance
  • Effective handling of driving behavior and weather volatility
  • Dynamic creation of reference profiles for operational conditions
  • Promising results with 78% precision, outperforming existing techniques

The symposium provided a fantastic platform to share our findings and exchange ideas with experts in the field. We are excited about the potential impact of our approach and look forward to further developments.


We are pleased to announce that our team recently participated in the 36th International Conference on Advanced Information Systems Engineering (CAiSE 2024) held in Limassol, Cyprus, from June 3-7.

Our presentation showcased our paper, "Predictive Maintenance in a Fleet Management System: The Navarchos Case," authored by Apostolos Giannoulidis, Anna-Valentini Michailidou, Theodoros Toliopoulos, Ioannis Constantinou, and Anastasios Gounaris.

This study addresses the critical challenge of vehicle fleet maintenance through the lens of predictive maintenance, examining the Navarchos fleet management system. In complex scenarios where traditional maintenance approaches often fall short, our research highlights the advantages of predictive techniques in enhancing vehicle safety and minimizing downtime. By detecting potential issues early, predictive maintenance can prevent costly repairs, maintain operational efficiency, and ensure the safety of the workforce.

Whether you specialize in fleet management, automotive safety, AI, or predictive analytics, our findings offer groundbreaking insights into innovative maintenance strategies that could transform your operations.

The conference was an incredible opportunity to engage with leading experts and gain valuable insights into the latest advancements in modeling, business process management, and process discovery. The talks, panels, and tutorials were particularly enriching, providing new perspectives and ideas for further enhancing our solutions.

A big thank you to the organizers and participants for a memorable and productive event!
